[PowerPC] Only use PLT annotations if using PIC relocation model

Summary:
The default static (non-PIC, non-PIE) model for 32-bit powerpc does
not use @PLT annotations and relocations in GCC. LLVM shouldn't use
@PLT annotations either, because it breaks secure-PLT linking with
(some versions of?) GNU LD.

Update the available-externally.ll test to reflect that default mode
should be the same as the static relocation, by using the same check
prefix.

[PowerPC] enable atomic.c in compiler_rt and do not check and forces
lock/lock_free decisions in compiled time

Summary:
Enables atomic.c in compiler_rt and forces clang to not emit a call for runtime
decision about lock/lock_free. At compiling time, if clang can't decide if
atomic operation can be lock free, it emits calls to external functions like
`__atomic_is_lock_free`, `__c11_atomic_is_lock_free` and
`__atomic_always_lock_free`, postponing decision to a runtime check. According
to LLVM code documentation, the mechanism exists due to differences between
x86_64 processors that can't be decided at runtime.

On PowerPC and PowerPCSPE (32 bits), we already know in advance it can't be lock
free, so we force the decision at compile time and avoid having to implement it
in an external library.

This patch was made after 32 bit users testing the PowePC32 bit ISO reported
llvm could not be compiled with in-base llvm due to `__atomic_load8` not
implemented.

addi a1, a0, %pcrel_lo(.Lpcrel_label1)

exposes an odd behaviour in which only the %pcrel_hi relocation is

0000000000000008 other_function:

The reason seems to be that in RISCVAsmBackend::shouldForceRelocation
we only consider the fragment but in RISCVMCExpr::evaluatePCRelLo we
consider the section. This usually works but there are cases where
the section may still be the same but the fragment may be another
one. In that case we end forcing a %pcrel_lo relocation without any
%pcrel_hi.

This patch makes RISCVAsmBackend::shouldForceRelocation use the
section, if any, to determine if the relocation must be forced or
not.

Merge commit da7b129b1 from llvm git (by James Clarke):

[RISCV] Don't force Local Exec TLS for non-PIC

Summary:

Forcing Local Exec TLS requires the use of copy relocations. Copy
relocations need special handling in the runtime linker when being
used against TLS symbols, which is present in glibc, but not in
FreeBSD nor musl, and so cannot be relied upon. Moreover, copy
relocations are a hack that embed the size of an object in the ABI
when it otherwise wouldn't be, and break protected symbols (which are
expected to be DSO local), whilst also wasting space, thus they
should be avoided whenever possible. As discussed in D70398, RISC-V
should move away from forcing Local Exec, and instead use Initial
Exec like other targets, with possible linker relaxation to follow.
The RISC-V GCC maintainers also intend to adopt this
more-conventional behaviour (see
https://github.com/riscv/riscv-elf-psabi-doc/issues/122).

[mips] Fix 64-bit address loading in case of applying 32-bit mask to
the result

If result of 64-bit address loading combines with 32-bit mask, LLVM
tries to optimize the code and remove "redundant" loading of upper
32-bits of the address. It leads to incorrect code on MIPS64 targets.

MIPS backend creates the following chain of commands to load 64-bit
address in the `MipsTargetLowering::getAddrNonPICSym64` method:
```
(add (shl (add (shl (add %highest(sym), %higher(sym)),
16),
%hi(sym)),
16),
%lo(%sym))
```

If the mask presents, LLVM decides to optimize the chain of commands.
It really does not make sense to load upper 32-bits because the
0x0fffffff mask anyway clears them. After removing redundant commands
we get this chain:
```
(add (shl (%hi(sym), 16), %lo(%sym))
```

There is no patterns matched `(MipsHi (i64 symbol))`. Due a bug in
`SYM_32` predicate definition, backend incorrectly selects a pattern
for a 32-bit symbols and uses the `lui` instruction for loading
`%hi(sym)`.

As a result we get incorrect set of instructions with unnecessary
16-bit left shifting:
```
lui at,0x0
R_MIPS_HI16 foo
dsll at,at,0x10
daddiu at,at,0
R_MIPS_LO16 foo
```

This patch resolves two problems:
- Fix `SYM_32/SYM_64` predicates to prevent selection of patterns
dedicated to 32-bit symbols in case of using N64 ABI.
- Add missed patterns for 64-bit symbols for `%hi/%lo`.

Fix PR42736.

[MIPS][ELF] Use PC-relative relocations in .eh_frame when possible

When compiling position-independent executables, we now use
DW_EH_PE_pcrel | DW_EH_PE_sdata4. However, the MIPS ABI does not define a
64-bit PC-relative ELF relocation so we cannot use sdata8 for the large
code model case. When using the large code model, we fall back to the
previous behaviour of generating absolute relocations.

With this change clang-generated .o files can be linked by LLD without
having to pass -Wl,-z,notext (which creates text relocations).
This is simpler than the approach used by ld.bfd, which rewrites the
.eh_frame section to convert absolute relocations into relative references.

I saw in D13104 that apparently ld.bfd did not accept pc-relative relocations
for MIPS ouput at some point. However, I also checked that recent ld.bfd
can process the clang-generated .o files so this no longer seems true.

[MIPS] Don't emit R_(MICRO)MIPS_JALR relocations against data symbols

The R_(MICRO)MIPS_JALR optimization only works when used against functions.
Using the relocation against a data symbol (e.g. function pointer) will
cause some linkers that don't ignore the hint in this case (e.g. LLD prior
to commit 5bab291) to generate a relative branch to the data symbol
which crashes at run time. Before this patch, LLVM was erroneously emitting
these relocations against local-dynamic TLS function pointers and global
function pointers with internal visibility.

Summary:

Merge commit da7b129b1 from llvm git (by James Clarke):

[RISCV] Don't force Local Exec TLS for non-PIC

Summary:

Forcing Local Exec TLS requires the use of copy relocations. Copy
relocations need special handling in the runtime linker when being
used against TLS symbols, which is present in glibc, but not in
FreeBSD nor musl, and so cannot be relied upon. Moreover, copy
relocations are a hack that embed the size of an object in the ABI
when it otherwise wouldn't be, and break protected symbols (which are
expected to be DSO local), whilst also wasting space, thus they
should be avoided whenever possible. As discussed in D70398, RISC-V
should move away from forcing Local Exec, and instead use Initial
Exec like other targets, with possible linker relaxation to follow.
The RISC-V GCC maintainers also intend to adopt this
more-conventional behaviour (see
https://github.com/riscv/riscv-elf-psabi-doc/issues/122).

[mips] Fix 64-bit address loading in case of applying 32-bit mask to
the result

If result of 64-bit address loading combines with 32-bit mask, LLVM
tries to optimize the code and remove "redundant" loading of upper
32-bits of the address. It leads to incorrect code on MIPS64 targets.

MIPS backend creates the following chain of commands to load 64-bit
address in the `MipsTargetLowering::getAddrNonPICSym64` method:
```
(add (shl (add (shl (add %highest(sym), %higher(sym)),
16),
%hi(sym)),
16),
%lo(%sym))
```

If the mask presents, LLVM decides to optimize the chain of commands.
It really does not make sense to load upper 32-bits because the
0x0fffffff mask anyway clears them. After removing redundant commands
we get this chain:
```
(add (shl (%hi(sym), 16), %lo(%sym))
```

There is no patterns matched `(MipsHi (i64 symbol))`. Due a bug in
`SYM_32` predicate definition, backend incorrectly selects a pattern
for a 32-bit symbols and uses the `lui` instruction for loading
`%hi(sym)`.

As a result we get incorrect set of instructions with unnecessary
16-bit left shifting:
```
lui at,0x0
R_MIPS_HI16 foo
dsll at,at,0x10
daddiu at,at,0
R_MIPS_LO16 foo
```

This patch resolves two problems:
- Fix `SYM_32/SYM_64` predicates to prevent selection of patterns
dedicated to 32-bit symbols in case of using N64 ABI.
- Add missed patterns for 64-bit symbols for `%hi/%lo`.

Fix PR42736.

[MIPS][ELF] Use PC-relative relocations in .eh_frame when possible

When compiling position-independent executables, we now use
DW_EH_PE_pcrel | DW_EH_PE_sdata4. However, the MIPS ABI does not define a
64-bit PC-relative ELF relocation so we cannot use sdata8 for the large
code model case. When using the large code model, we fall back to the
previous behaviour of generating absolute relocations.

With this change clang-generated .o files can be linked by LLD without
having to pass -Wl,-z,notext (which creates text relocations).
This is simpler than the approach used by ld.bfd, which rewrites the
.eh_frame section to convert absolute relocations into relative references.

I saw in D13104 that apparently ld.bfd did not accept pc-relative relocations
for MIPS ouput at some point. However, I also checked that recent ld.bfd
can process the clang-generated .o files so this no longer seems true.

Using the relocation against a data symbol (e.g. function pointer) will
cause some linkers that don't ignore the hint in this case (e.g. LLD prior
to commit 5bab291) to generate a relative branch to the data symbol
which crashes at run time. Before this patch, LLVM was erroneously emitting
these relocations against local-dynamic TLS function pointers and global
function pointers with internal visibility.

[RISCV] Don't force Local Exec TLS for non-PIC

Summary:

Forcing Local Exec TLS requires the use of copy relocations. Copy
relocations need special handling in the runtime linker when being
used against TLS symbols, which is present in glibc, but not in
FreeBSD nor musl, and so cannot be relied upon. Moreover, copy
relocations are a hack that embed the size of an object in the ABI
when it otherwise wouldn't be, and break protected symbols (which are
expected to be DSO local), whilst also wasting space, thus they
should be avoided whenever possible. As discussed in D70398, RISC-V
should move away from forcing Local Exec, and instead use Initial
Exec like other targets, with possible linker relaxation to follow.
The RISC-V GCC maintainers also intend to adopt this
more-conventional behaviour (see
https://github.com/riscv/riscv-elf-psabi-doc/issues/122).

[mips] Fix 64-bit address loading in case of applying 32-bit mask to
the result

If result of 64-bit address loading combines with 32-bit mask, LLVM
tries to optimize the code and remove "redundant" loading of upper
32-bits of the address. It leads to incorrect code on MIPS64 targets.

MIPS backend creates the following chain of commands to load 64-bit
address in the `MipsTargetLowering::getAddrNonPICSym64` method:
```
(add (shl (add (shl (add %highest(sym), %higher(sym)),
16),
%hi(sym)),
16),
%lo(%sym))
```

If the mask presents, LLVM decides to optimize the chain of commands.
It really does not make sense to load upper 32-bits because the
0x0fffffff mask anyway clears them. After removing redundant commands
we get this chain:
```
(add (shl (%hi(sym), 16), %lo(%sym))
```

There is no patterns matched `(MipsHi (i64 symbol))`. Due a bug in
`SYM_32` predicate definition, backend incorrectly selects a pattern
for a 32-bit symbols and uses the `lui` instruction for loading
`%hi(sym)`.

As a result we get incorrect set of instructions with unnecessary
16-bit left shifting:
```
lui at,0x0
R_MIPS_HI16 foo
dsll at,at,0x10
daddiu at,at,0
R_MIPS_LO16 foo
```

This patch resolves two problems:
- Fix `SYM_32/SYM_64` predicates to prevent selection of patterns
dedicated to 32-bit symbols in case of using N64 ABI.
- Add missed patterns for 64-bit symbols for `%hi/%lo`.

Fix PR42736.

[MIPS][ELF] Use PC-relative relocations in .eh_frame when possible

When compiling position-independent executables, we now use
DW_EH_PE_pcrel | DW_EH_PE_sdata4. However, the MIPS ABI does not define a
64-bit PC-relative ELF relocation so we cannot use sdata8 for the large
code model case. When using the large code model, we fall back to the
previous behaviour of generating absolute relocations.

With this change clang-generated .o files can be linked by LLD without
having to pass -Wl,-z,notext (which creates text relocations).
This is simpler than the approach used by ld.bfd, which rewrites the
.eh_frame section to convert absolute relocations into relative references.

I saw in D13104 that apparently ld.bfd did not accept pc-relative relocations
for MIPS ouput at some point. However, I also checked that recent ld.bfd
can process the clang-generated .o files so this no longer seems true.

Summary:
Enables atomic.c in compiler_rt and forces clang to not emit a call for runtime
decision about lock/lock_free. At compiling time, if clang can't decide if
atomic operation can be lock free, it emits calls to external functions like
`__atomic_is_lock_free`, `__c11_atomic_is_lock_free` and
`__atomic_always_lock_free`, postponing decision to a runtime check. According
to LLVM code documentation, the mechanism exists due to differences between
x86_64 processors that can't be decided at runtime.

On PowerPC and PowerPCSPE (32 bits), we already know in advance it can't be lock
free, so we force the decision at compile time and avoid having to implement it
in an external library.

This patch was made after 32 bit users testing the PowePC32 bit ISO reported
llvm could not be compiled with in-base llvm due to `__atomic_load8` not

64-bit PC-relative ELF relocation so we cannot use sdata8 for the large
code model case. When using the large code model, we fall back to the
previous behaviour of generating absolute relocations.

With this change clang-generated .o files can be linked by LLD without
having to pass -Wl,-z,notext (which creates text relocations).
This is simpler than the approach used by ld.bfd, which rewrites the
.eh_frame section to convert absolute relocations into relative references.

I saw in D13104 that apparently ld.bfd did not accept pc-relative relocations
for MIPS ouput at some point. However, I also checked that recent ld.bfd
can process the clang-generated .o files so this no longer seems true.

[MIPS] Don't emit R_(MICRO)MIPS_JALR relocations against data symbols

The R_(MICRO)MIPS_JALR optimization only works when used against functions.
Using the relocation against a data symbol (e.g. function pointer) will
cause some linkers that don't ignore the hint in this case (e.g. LLD prior
to commit 5bab291) to generate a relative branch to the data symbol
which crashes at run time. Before this patch, LLVM was erroneously emitting
these relocations against local-dynamic TLS function pointers and global
function pointers with internal visibility.

we only consider the fragment but in RISCVMCExpr::evaluatePCRelLo we

one. In that case we end forcing a %pcrel_lo relocation without any

[RISCV] Don't force Local Exec TLS for non-PIC

Summary:

Forcing Local Exec TLS requires the use of copy relocations. Copy
relocations need special handling in the runtime linker when being
used against TLS symbols, which is present in glibc, but not in
FreeBSD nor musl, and so cannot be relied upon. Moreover, copy
relocations are a hack that embed the size of an object in the ABI
when it otherwise wouldn't be, and break protected symbols (which are
expected to be DSO local), whilst also wasting space, thus they
should be avoided whenever possible. As discussed in D70398, RISC-V
should move away from forcing Local Exec, and instead use Initial
Exec like other targets, with possible linker relaxation to follow.
The RISC-V GCC maintainers also intend to adopt this
more-conventional behaviour (see
https://github.com/riscv/riscv-elf-psabi-doc/issues/122).

[mips] Fix 64-bit address loading in case of applying 32-bit mask to
the result

If result of 64-bit address loading combines with 32-bit mask, LLVM
tries to optimize the code and remove "redundant" loading of upper
32-bits of the address. It leads to incorrect code on MIPS64 targets.

MIPS backend creates the following chain of commands to load 64-bit
address in the `MipsTargetLowering::getAddrNonPICSym64` method:
```
(add (shl (add (shl (add %highest(sym), %higher(sym)),
16),
%hi(sym)),
16),
%lo(%sym))
```

If the mask presents, LLVM decides to optimize the chain of commands.
It really does not make sense to load upper 32-bits because the
0x0fffffff mask anyway clears them. After removing redundant commands
we get this chain:
```
(add (shl (%hi(sym), 16), %lo(%sym))
```

There is no patterns matched `(MipsHi (i64 symbol))`. Due a bug in
`SYM_32` predicate definition, backend incorrectly selects a pattern
for a 32-bit symbols and uses the `lui` instruction for loading
`%hi(sym)`.

As a result we get incorrect set of instructions with unnecessary
16-bit left shifting:
```
lui at,0x0
R_MIPS_HI16 foo
dsll at,at,0x10
daddiu at,at,0
R_MIPS_LO16 foo
```

This patch resolves two problems:
- Fix `SYM_32/SYM_64` predicates to prevent selection of patterns
dedicated to 32-bit symbols in case of using N64 ABI.
- Add missed patterns for 64-bit symbols for `%hi/%lo`.

Fix PR42736.

On PowerPC and PowerPCSPE (32 bits), we already know in advance it can't be lock
free, so we force the decision at compile time and avoid having to implement it
in an external library.

This patch was made after 32 bit users testing the PowePC32 bit ISO reported
llvm could not be compiled with in-base llvm due to `__atomic_load8` not
implemented.

[RISCV] Fix evaluation of %pcrel_lo

addi a1, a0, %pcrel_lo(.Lpcrel_label1)
.p2align 2 # Causes a new fragment to be emitted

.type other_function,@function
other_function:

exposes an odd behaviour in which only the %pcrel_hi relocation is
evaluated but not the %pcrel_lo.

$ llvm-mc -triple riscv64 -filetype obj t.s | llvm-objdump -d -r -

0000000000000008 other_function:

The reason seems to be that in RISCVAsmBackend::shouldForceRelocation
we only consider the fragment but in RISCVMCExpr::evaluatePCRelLo we
consider the section. This usually works but there are cases where
the section may still be the same but the fragment may be another
one. In that case we end forcing a %pcrel_lo relocation without any
%pcrel_hi.

This patch makes RISCVAsmBackend::shouldForceRelocation use the
section, if any, to determine if the relocation must be forced or
not.

Merge commit da7b129b1 from llvm git (by James Clarke):

[RISCV] Don't force Local Exec TLS for non-PIC

Summary:

Forcing Local Exec TLS requires the use of copy relocations. Copy
relocations need special handling in the runtime linker when being
used against TLS symbols, which is present in glibc, but not in
FreeBSD nor musl, and so cannot be relied upon. Moreover, copy
relocations are a hack that embed the size of an object in the ABI
when it otherwise wouldn't be, and break protected symbols (which are
expected to be DSO local), whilst also wasting space, thus they
should be avoided whenever possible. As discussed in D70398, RISC-V
should move away from forcing Local Exec, and instead use Initial
Exec like other targets, with possible linker relaxation to follow.
The RISC-V GCC maintainers also intend to adopt this
more-conventional behaviour (see
https://github.com/riscv/riscv-elf-psabi-doc/issues/122).

[mips] Fix 64-bit address loading in case of applying 32-bit mask to
the result

If result of 64-bit address loading combines with 32-bit mask, LLVM
tries to optimize the code and remove "redundant" loading of upper
32-bits of the address. It leads to incorrect code on MIPS64 targets.

MIPS backend creates the following chain of commands to load 64-bit
address in the `MipsTargetLowering::getAddrNonPICSym64` method:
```
(add (shl (add (shl (add %highest(sym), %higher(sym)),
16),
%hi(sym)),
16),
%lo(%sym))
```

If the mask presents, LLVM decides to optimize the chain of commands.
It really does not make sense to load upper 32-bits because the
0x0fffffff mask anyway clears them. After removing redundant commands
we get this chain:
```
(add (shl (%hi(sym), 16), %lo(%sym))
```

There is no patterns matched `(MipsHi (i64 symbol))`. Due a bug in
`SYM_32` predicate definition, backend incorrectly selects a pattern
for a 32-bit symbols and uses the `lui` instruction for loading
`%hi(sym)`.

As a result we get incorrect set of instructions with unnecessary
16-bit left shifting:
```
lui at,0x0
R_MIPS_HI16 foo
dsll at,at,0x10
daddiu at,at,0
R_MIPS_LO16 foo
```

This patch resolves two problems:
- Fix `SYM_32/SYM_64` predicates to prevent selection of patterns
dedicated to 32-bit symbols in case of using N64 ABI.
- Add missed patterns for 64-bit symbols for `%hi/%lo`.

Fix PR42736.

[MIPS][ELF] Use PC-relative relocations in .eh_frame when possible

When compiling position-independent executables, we now use
DW_EH_PE_pcrel | DW_EH_PE_sdata4. However, the MIPS ABI does not define a
64-bit PC-relative ELF relocation so we cannot use sdata8 for the large
code model case. When using the large code model, we fall back to the
previous behaviour of generating absolute relocations.

With this change clang-generated .o files can be linked by LLD without
having to pass -Wl,-z,notext (which creates text relocations).
This is simpler than the approach used by ld.bfd, which rewrites the
.eh_frame section to convert absolute relocations into relative references.

I saw in D13104 that apparently ld.bfd did not accept pc-relative relocations
for MIPS ouput at some point. However, I also checked that recent ld.bfd
can process the clang-generated .o files so this no longer seems true.

[MIPS] Don't emit R_(MICRO)MIPS_JALR relocations against data symbols

The R_(MICRO)MIPS_JALR optimization only works when used against functions.
Using the relocation against a data symbol (e.g. function pointer) will
cause some linkers that don't ignore the hint in this case (e.g. LLD prior
to commit 5bab291) to generate a relative branch to the data symbol
which crashes at run time. Before this patch, LLVM was erroneously emitting
these relocations against local-dynamic TLS function pointers and global
function pointers with internal visibility.

The second commit is not strictly necessary for clang+lld since LLD9 will
not perform the R_MIPS_JALR optimization (it was only added for 10) but it
is probably required in order to use recent ld.bfd.

H A Dswap_pager.hdiff 67082 Fri Oct 13 14:44:34 MDT 2000 dillon The swap bitmap allocator was not calculating the bitmap size properly
in the face of non-stripe-aligned swap areas. The bug could cause a
panic during boot.

Refuse to configure a swap area that is too large (67 GB or so)

Properly document the power-of-2 requirement for SWB_NPAGES.

The patch is slightly different then the one Tor enclosed in the P.R.,
but accomplishes the same thing.
