Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol (i.e. the definition of the symbol is in a different DSO), the computation of the static TLS offset used the wrong DSO. This would effectively mean the wrong address was computed (PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining the symbol).
This code uses __UNCONST to avoid the vast interface changes for this special case.
(2) If symbols from a DSO loaded via dlopen are used with both global-dynamic/local-dynamic and initial-exec relocations AND a initial-exec relocation was resolved first in a thread, a split brain situation could exist where the dynamic relocations would use one memory block (separate allocation) and the initial-exec relocations the static per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has already used a GD/LD allocation, bail out. Since IE relocations are used only in the GOT, this will prevent the dlopen. This is a bit more aggressive than necessary, but a full blown reference counting doesn't seem to be justified.

Hidden ifunc is now supported on all ifunc platforms, even when using -fno-plt. The combination of -fno-plt and relro is broken due to incorrect GNU ld output though.

Move the complex logic for dynamically writing branches from ld.elf_so into a header for reuse in crt0.o for static ifunc support. Change the existing logic for sparc64 to use the Bicc variant of ba,a as it allows +-8MB displacement compared to the BPcc variant's +-1MB. Teach the sparc variant the same trick for using ba,a and not sethi+jmp when possible.

Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and breaks the use of shared locks for the common symbol lookup case. It is unlikely to provide any benefit for lazy binding or PLT lookups, so provide equivalent functionality in the non-PLT relocation handling loop by checking if the symbol used by the current relocation is the same as the one used during the last lookup. No inter-object cachine is done as it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by the new method.

branches: 1.48.8; Add basic support for indirect functions. It allows providing a public function symbol with an implementation choosen at run time. Refactor calls to functions by address in ld.elf_so to create temporary function descriptors on the stack, if the address is not leaked outside.
Limitations: - no support for initialising static storage with function pointers - no support for unnamed resolver functions

Split _rtld_relocate_plt_object() into two MD functions: * _rtld_relocate_plt_lazy() fixes up all the relocs pointing to the PLT. (On most platforms it just does a simple base-relative fixup; on SPARC it does nothing.) * _rtld_relocate_plt_object() does immediate binding for a PLT entry. The basic gist is that this saves a bit of time on SPARC (where the iteration through the pltrela table was gratuitous), and a little less time on all other platforms. A whole lot of #ifdef'ed crap is moved out of reloc.c, too.

Split _rtld_relocate_plt_object() into two MD functions: * _rtld_relocate_plt_lazy() fixes up all the relocs pointing to the PLT. (On most platforms it just does a simple base-relative fixup; on SPARC it does nothing.) * _rtld_relocate_plt_object() does immediate binding for a PLT entry. The basic gist is that this saves a bit of time on SPARC (where the iteration through the pltrela table was gratuitous), and a little less time on all other platforms. A whole lot of #ifdef'ed crap is moved out of reloc.c, too.
NOT tested on: hppa sh x86_64

Rework ifunc support to address a number of short comings: - Move to a shared _rtld_call_ifunc for rel and rela architectures - Architectures using rel format must patch IRELATIVE non-PLT relocations like RELATIVE in additition to the later ifunc handling - Consistently record the delta to the end of the relocation group for non-PLT IRELATIVE relocations
Hidden ifunc is now supported on all ifunc platforms, even when using -fno-plt. The combination of -fno-plt and relro is broken due to incorrect GNU ld output though.

Move the complex logic for dynamically writing branches from ld.elf_so into a header for reuse in crt0.o for static ifunc support. Change the existing logic for sparc64 to use the Bicc variant of ba,a as it allows +-8MB displacement compared to the BPcc variant's +-1MB. Teach the sparc variant the same trick for using ba,a and not sethi+jmp when possible.

Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and breaks the use of shared locks for the common symbol lookup case. It is unlikely to provide any benefit for lazy binding or PLT lookups, so provide equivalent functionality in the non-PLT relocation handling loop by checking if the symbol used by the current relocation is the same as the one used during the last lookup. No inter-object cachine is done as it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by the new method.

Split _rtld_relocate_plt_object() into two MD functions: * _rtld_relocate_plt_lazy() fixes up all the relocs pointing to the PLT. (On most platforms it just does a simple base-relative fixup; on SPARC it does nothing.) * _rtld_relocate_plt_object() does immediate binding for a PLT entry. The basic gist is that this saves a bit of time on SPARC (where the iteration through the pltrela table was gratuitous), and a little less time on all other platforms. A whole lot of #ifdef'ed crap is moved out of reloc.c, too.

Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and breaks the use of shared locks for the common symbol lookup case. It is unlikely to provide any benefit for lazy binding or PLT lookups, so provide equivalent functionality in the non-PLT relocation handling loop by checking if the symbol used by the current relocation is the same as the one used during the last lookup. No inter-object cachine is done as it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by the new method.

Limitations: - no support for initialising static storage with function pointers - no support for unnamed resolver functions

Initialize _rtld_sym_zero.st_value to -_rtld_objself.maprelocbase.

Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and breaks the use of shared locks for the common symbol lookup case. It is unlikely to provide any benefit for lazy binding or PLT lookups, so provide equivalent functionality in the non-PLT relocation handling loop by checking if the symbol used by the current relocation is the same as the one used during the last lookup. No inter-object cachine is done as it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by the new method.

Split _rtld_relocate_plt_object() into two MD functions: * _rtld_relocate_plt_lazy() fixes up all the relocs pointing to the PLT. (On most platforms it just does a simple base-relative fixup; on SPARC it does nothing.) * _rtld_relocate_plt_object() does immediate binding for a PLT entry. The basic gist is that this saves a bit of time on SPARC (where the iteration through the pltrela table was gratuitous), and a little less time on all other platforms. A whole lot of #ifdef'ed crap is moved out of reloc.c, too.

Split _rtld_relocate_plt_object() into two MD functions: * _rtld_relocate_plt_lazy() fixes up all the relocs pointing to the PLT. (On most platforms it just does a simple base-relative fixup; on SPARC it does nothing.) * _rtld_relocate_plt_object() does immediate binding for a PLT entry. The basic gist is that this saves a bit of time on SPARC (where the iteration through the pltrela table was gratuitous), and a little less time on all other platforms. A whole lot of #ifdef'ed crap is moved out of reloc.c, too.

Add basic support for indirect functions. It allows providing a public function symbol with an implementation choosen at run time. Refactor calls to functions by address in ld.elf_so to create temporary function descriptors on the stack, if the address is not leaked outside.
Limitations: - no support for initialising static storage with function pointers - no support for unnamed resolver functions
