updates for GCC 12 (relatively tiny).

- gcov-iov.h is now called version.h and we build it directly.
- need to explicitly ask for bversion.h gtyp-input.list to be built.

don't rename codecvt.cc here, do it in a Makefile when consumed.

since the Makefiles already need updates for these, it's easier
if all of the changes are there.

fetch experimental_headers, experimental_bits_headers, and ext_host_headers
to install install experimental/* and ext/opt_random.h.

fetch omp-device-properties.h and don't try to fetch sanitizer

make mknative-gcc.old for GCC 9. begin to update mknative-gcc for GCC 10.

more consolidation and properly condition all variables like previously.

consolidate a bunch of libstdc++ variable collection.

oops, pull out the value of pstl_headers.

pass down earm* not earmv5* to mknative-gcc.

disable fetching stuff from libsanitizer for now. it needs libstdc++
to build in mknative using gcc makefiles, and our locale changes break
the "normal" build of this.

make sure MKNATIVE_TARGET is always set. since mknative-gcc doesn't
care about the version any more (we keep two versions for gcc/gcc.old)
simply set it to "gcc".

pull out a few more things for GCC 9.

port to GCC 9.3.

set _OUTDIRBASE depending on $0, and then set _OUTDIR based on this.
now you can copy mknative-gcc to mknative-gcc.old without edit.

mknative-gcc is for GCC 8.4.
mknative-gcc.old is supposed to be for GCC 7, but is the GCC 6
version. update it and mark it for GCC 7.5.

arm needs more files

copy arm-cpu.h and arm-isa.h for arm platforms.

branches: 1.101.2;
pull out libstdc++ config.h as-is, for gnu.ver processing.
pull out the cxx11_sources and cxx98_sources values to avoid hard coding.

- build the gthr*.h files to be installed on the fly, instead of
having dozens of copies of the same thing in the tree.
- don't fetch any gthr*.h files.
- delete ancient gthr-tpf.h that was removed in GCC 4.8 or so.

this should fix the call_once tests for real now.

common-target source list is MD. make it so.

- don't getlinks here, they're no longer used.
- pullout the libcommon, libcommon-target and libgomp source list so they
don't have to be hard coded in the reachover makefile

- use --with-default-libstdcxx-abi=new for GCC, otherwise we get the
old ABI with --disable-libstdcxx-dual-abi
- fix libbacktrace mknative
- find gthr-default.h for libstdc++ mknative
- fetch FILESYSTEM_SOURCES

make includes works now.

pull out more data needed for headers and fix gthr-defaults.h.

libgcc_s has multiple symbols.

also pull out these variables:
enable_execute_stack
unwind_header
md_unwind_header
sfp_machine_header
thread_header

also pullout INTERNAL_CFLAGS for the libgcc build, where it may have
-DHAVE_CC_TLS defined on the command line. (we already collect all
the other components.)

in configargs.h, as well as normalising to /usr/src, normalise the
--build to the same as the --host, so that it never changes based
upon the host you ran mknative on. (some recent changes are only
because i updated a system from netbsd-7 to netbsd-8. this will
avoid that in the future.)

pullout port_specific_symbol_files from libstdc++.

use the variable for the source dir instead of duplicating it.

- rename the c98 and c11 subdir codecvt.cc files while extracting
them with mknative
- grab GGC_H as well, and use it in dependency lists

update for GCC 5.3 libgcov and libstdc++

very first baby steps towards GCC 5.3 mknative.

add a comment saying this is for GCC 4.8

kill the -fPIC that m68000 ends up with, fixing it in the specs
is not trivial..

canonicalise the src dir to /usr/src, so it doesn't matter
where we run mknative.

Don't grab libstdc++-v3/config.h it's not used.

branches: 1.78.2;
don't collect gthr-default.h anymore.

don't collect c++allocator.h. we copy it via G_ALLOCATOR_H we've
already pulled out, and the extra copy can confuse make when it
has an older timestamp than the copy in dist/libstdc++-v3/.

prepare for moving GCC 4.5 into gcc.old:

- convert to using ${EXTERNAL_GCC_SUBDIR}
- define base-external-gpl3-gcc* subdir as GCC_SUBDIR
- use <bsd.init.mk> over <bsd.own.mk> for a bunch of places; mostly
because it arranges for ../Makefile.inc to be included earlier, and
don't bother including the latter if the former is already included.
- move all .PATH: settings after <bsd.{own,lib}.mk> so that all
valid variables are set before it is evaluated
- rename mknative-gcc* to match their subdir name.

XXX the relationship between the Makefile.inc/Makefile.gcc_path files
is kind of sketchy, it would be great if this was fixed.

The mpfr sources moved down into a src directory - deal with this in
mknative.

some more updates for GCC 4.5.

Handle cases where database text files don't exist.

Call "template sources" as "tmplsrcs", not "tmpsrcs". Requested by mrg@.

Prefix per-library *.mk files with libs.*.

Now that we know what sources are needed to build a given library, we need
the rules how to build those sources. Generate makefiles defining ${COPTS},
${CPPFLAGS}, and ${SRCS} (== template).

Note that ${CPPFLAGS} is actually dfined as _CPPFLAGS like
_CPPFLAGS.tmp___gcc_bcmp.c=-DL__gcc_bcmp
and used to generate wrapper files (e.g. tmp___gcc_bcmp.c). Otherwise it's
automagically passed to ${CC} by bsd.*.mk.

For each library, generate a makefile of the list of template sources too.

For each library, generate a list of sources (*.[cS]).

We create wrapper sources (tmp_*.[cS]) on-the-fly and compile them. For
example, __gcc_bcmp() is compiled using tmp___gcc_bcmp.c, which #define's
L__gcc_bcmp and #include's libgcc2.c.

Move these analyzing functions into one place, get_libgcc_new_analyze().

Typo.

Generate lists of template sources ("tmpsrcs") for each libraries. We'll
need these to create wrappers of tmpsrcs and define correct dependencies.

Generate *.o -> template *.[cS] ("tmpsrc") mapping.

Functions are built from a template (tmpsrc). We create wrapper sources
(src) and define necessary defines and #include tmpsrc.

- Generate a list of CPP flags used to build *.o. Some files are build
repeatedly with different -DXXX to generate similar objects (e.g. different
type size).

- Generate a list of other CC options to build *.o.

(See my sed-fu using hold space in get_libgcc_list_objs_xflags().)

- Generate a list of *.o -> lib*.{a,so} mapping. This is also known by
parsing dependency lines in libgcc.mk.

- Generate a list of *.o -> *.{c,S} mapping. *.S files are known as
${LIB1ASMFUNCS}. Assume other *.o files are built from *.c. This information
is needed to generated wrapper sources later.

Generate lists of functions built in libgcc libraries. This is known by
pattern matching dependency lines in libgcc.mk.

Generate a list of functions provided as *.S.

Define paths of newly generated files.

Start implementing the new style libgcc "mknative" converter which generates
BSD makefiles to build libgcc. The goal is to build all functions rather
than managing the set of functions in gnu/lib/libgcc/Makefile.in by hand.

Because of the complexity of the build procedure, I leave not only generated
makefiles but also intermediate, analyzed data so that people can verify that
the conversion is done correctly.

- add a i386/t-netbsd64 makefile fragment to build 32/64 bit
libgcc/multilib on amd64
- enable the 32/64 bit libgcc/multilib support on sparc64
- adapt mknative-gcc to grab multilib.h

set _OUTDIRBASE depending on $0, and then set _OUTDIR based on this.
now you can copy mknative-gcc to mknative-gcc.old without edit.

mknative-gcc is for GCC 8.4.
mknative-gcc.old is supposed to be for GCC 7, but is the GCC 6
version. update it and mark it for GCC 7.5.

arm needs more files

copy arm-cpu.h and arm-isa.h for arm platforms.

branches: 1.101.2;
pull out libstdc++ config.h as-is, for gnu.ver processing.
pull out the cxx11_sources and cxx98_sources values to avoid hard coding.

- build the gthr*.h files to be installed on the fly, instead of
having dozens of copies of the same thing in the tree.
- don't fetch any gthr*.h files.
- delete ancient gthr-tpf.h that was removed in GCC 4.8 or so.

this should fix the call_once tests for real now.

common-target source list is MD. make it so.

- don't getlinks here, they're no longer used.
- pullout the libcommon, libcommon-target and libgomp source list so they
don't have to be hard coded in the reachover makefile

- use --with-default-libstdcxx-abi=new for GCC, otherwise we get the
old ABI with --disable-libstdcxx-dual-abi
- fix libbacktrace mknative
- find gthr-default.h for libstdc++ mknative
- fetch FILESYSTEM_SOURCES

make includes works now.

pull out more data needed for headers and fix gthr-defaults.h.

libgcc_s has multiple symbols.

also pull out these variables:
enable_execute_stack
unwind_header
md_unwind_header
sfp_machine_header
thread_header

also pullout INTERNAL_CFLAGS for the libgcc build, where it may have
-DHAVE_CC_TLS defined on the command line. (we already collect all
the other components.)

in configargs.h, as well as normalising to /usr/src, normalise the
--build to the same as the --host, so that it never changes based
upon the host you ran mknative on. (some recent changes are only
because i updated a system from netbsd-7 to netbsd-8. this will
avoid that in the future.)

branches: 1.92.2; 1.92.4;
also fetch GCOV_DUMP_OBJS.

pullout port_specific_symbol_files from libstdc++.

use the variable for the source dir instead of duplicating it.

branches: 1.89.6;
revert our changes; softfloat removal is now done in libgcc/config.host

We provide our own soft-float implementation in libc, so elide the libgcc
sources for it.

branches: 1.87.2;
set NETBSD_GCC_VERSION for GCC 5.3 separately.
don't collect crtstuff anymore.

grab insn-modes.h, and do the libgcc bootstrap from gcc as well.

- pull i386-builtin-types.inc automatically on x86
- reenable cxx rt support
- don't grab insn-modes.h, we build it
- rename the c98 and c11 subdir codecvt.cc files while extracting
them with mknative
- grab GGC_H as well, and use it in dependency lists

update for GCC 5.3 libgcov and libstdc++

very first baby steps towards GCC 5.3 mknative.

add a comment saying this is for GCC 4.8

kill the -fPIC that m68000 ends up with, fixing it in the specs
is not trivial..

canonicalise the src dir to /usr/src, so it doesn't matter
where we run mknative.

Don't grab libstdc++-v3/config.h it's not used.

branches: 1.78.2;
don't collect gthr-default.h anymore.

don't collect c++allocator.h. we copy it via G_ALLOCATOR_H we've
already pulled out, and the extra copy can confuse make when it
has an older timestamp than the copy in dist/libstdc++-v3/.

prepare for moving GCC 4.5 into gcc.old:

- convert to using ${EXTERNAL_GCC_SUBDIR}
- define base-external-gpl3-gcc* subdir as GCC_SUBDIR
- use <bsd.init.mk> over <bsd.own.mk> for a bunch of places; mostly
because it arranges for ../Makefile.inc to be included earlier, and
don't bother including the latter if the former is already included.
- move all .PATH: settings after <bsd.{own,lib}.mk> so that all
valid variables are set before it is evaluated
- rename mknative-gcc* to match their subdir name.

XXX the relationship between the Makefile.inc/Makefile.gcc_path files
is kind of sketchy, it would be great if this was fixed.

The mpfr sources moved down into a src directory - deal with this in
mknative.

update to MPC 1.0.1.

Deleted 1 line too many in previous commit.

g/c gcc3 goop

pass both NEWCONFIGDIR and NETBSDSRCDIR to mknative-gcc.

Create a sanitise_includes function and use it everywhere it's needed.

Avoid populating mknative output with gmp,mpfr, and mpc source
directories

More tweaks. I didn't manage to complete a mknative from scratch run, but
this is a step in the right direction.

branches: 1.67.2;
Grab CRTSTUFF_T_CFLAGS_S.

Gentlement start your mknative runs.

Fix bootstrap-libgcc for gcc 4.5

branches: 1.65.2;
Fix PPC _SOFT_FLOAT

since omp.h is part of libgomp, put it in the libgomp files not the
libstdc++ files.

add libgomp support. needed by "cc -fopenmp", that koffice 2.3 wants to use.

Add an inline ex script to modify configargs.h for powerpc to auto-enable
-msoft-float.

fix the previous

-I$DESTDIR/usr/include is escaping into the generated files from
the native-gcc run. add some sed commands to remove them.

copy sysroot-suffix.h as well, for sh3.

also pull out LIB2ADD_ST for libgcc.

avoid creating an unused directory.

- call each ${MKNATIVE_CONFIG_TARGET_LIBS} target separately
- comment out maybe-all-target-libgcc
- cope with the special transformation needed for gtyp-input.list

fix previous; they belong in _headers1

also pull tr1_impl_headers parallel_headers and decimal_headers for libstdc++

fix all-tree.def, and add gtyp-input.list

fix the path for libdecnumber.

get libdecnumber info out of GCC.

also need bversion.h

some more updates for GCC 4.5.

output stuff to the right libiberty dir for gcc 4.5.

get this some what working with GCC 4.5. i at least have managed to
get crtstuff and libgcc to build for amd64, and have linked and tested
/bin/sh with all these GCC 4.5 compiled part.

initial port to HAVE_GCC = 45. mknative-gcc parts are from me
and are largely untested, most of the rest is from chuq.

branches: 1.45.4;
get_libgcc_new: Make previous work for digit only ABI names.

get_libgcc_new: Teach multilib.

Skip parameters for multilib build for now.

Handle cases where *.asm is listed in LIB2FUNCS_EXTRA (gcc/config/rs6000).

Handle cases where database text files don't exist.

Call "template sources" as "tmplsrcs", not "tmpsrcs". Requested by mrg@.

Prefix per-library *.mk files with libs.*.

Now that we know what sources are needed to build a given library, we need
the rules how to build those sources. Generate makefiles defining ${COPTS},
${CPPFLAGS}, and ${SRCS} (== template).

Note that ${CPPFLAGS} is actually dfined as _CPPFLAGS like
_CPPFLAGS.tmp___gcc_bcmp.c=-DL__gcc_bcmp
and used to generate wrapper files (e.g. tmp___gcc_bcmp.c). Otherwise it's
automagically passed to ${CC} by bsd.*.mk.

For each library, generate a makefile of the list of template sources too.

For each library, generate a list of sources (*.[cS]).

We create wrapper sources (tmp_*.[cS]) on-the-fly and compile them. For
example, __gcc_bcmp() is compiled using tmp___gcc_bcmp.c, which #define's
L__gcc_bcmp and #include's libgcc2.c.

Move these analyzing functions into one place, get_libgcc_new_analyze().

Typo.

Generate lists of template sources ("tmpsrcs") for each libraries. We'll
need these to create wrappers of tmpsrcs and define correct dependencies.

Generate *.o -> template *.[cS] ("tmpsrc") mapping.

Functions are built from a template (tmpsrc). We create wrapper sources
(src) and define necessary defines and #include tmpsrc.

- Generate a list of CPP flags used to build *.o. Some files are build
repeatedly with different -DXXX to generate similar objects (e.g. different
type size).

- Generate a list of other CC options to build *.o.

(See my sed-fu using hold space in get_libgcc_list_objs_xflags().)

- Generate a list of *.o -> lib*.{a,so} mapping. This is also known by
parsing dependency lines in libgcc.mk.

- Generate a list of *.o -> *.{c,S} mapping. *.S files are known as
${LIB1ASMFUNCS}. Assume other *.o files are built from *.c. This information
is needed to generated wrapper sources later.

Generate lists of functions built in libgcc libraries. This is known by
pattern matching dependency lines in libgcc.mk.

Generate a list of functions provided as *.S.

Define paths of newly generated files.

Start implementing the new style libgcc "mknative" converter which generates
BSD makefiles to build libgcc. The goal is to build all functions rather
than managing the set of functions in gnu/lib/libgcc/Makefile.in by hand.

Because of the complexity of the build procedure, I leave not only generated
makefiles but also intermediate, analyzed data so that people can verify that
the conversion is done correctly.

- add a i386/t-netbsd64 makefile fragment to build 32/64 bit
libgcc/multilib on amd64
- enable the 32/64 bit libgcc/multilib support on sparc64
- adapt mknative-gcc to grab multilib.h
- use --enable-multilib on amd64 and sparc64

none of this affects the installed tools yet, just the src/tools one.

Grab libgcov stuff.

Collect the libobjc config.h

branches: 1.22.4; 1.22.10;
convert build/ggc-none.o to build-ggc-none.lo.

also grab ${_extravars} for GCC4 in the get_gcc() function.

Fixes for mknative runs on gcc3.

- get the information from a gcc3 .native
- don't get gcc4 variables
- put back the getvars for SHLIB_LINK SHLIB_MULTILIB as they work
on gcc3 and leave as XXX'd on gcc4.

I've re-arranged some of the variables to minimise the differences, but
didn't do them all.

make this work for GCC3 one again.

also grab ALL_OPT_FILES from gcc/Makefile for libobjc4.

make sure that c++ headers work again.

support GCC4:
- look in gnu/dist/gcc4
- don't build fortran
- use /usr/bin/env -i so that gmake works (XXX - breaks from MAKEFLAGS
in the build.sh generated makewrapper.)
- use gmake and Makefile.gmakehost
- update .native/.configure_done target

mirror a fix from mknative-binutils:
>fix the sed expression that pulls VPATH out of the makefile to work

Add code to extract make vars for GCC crtstuff.

Add some more variables used to build libgcc_s.

Part of the fix for PR 22452.

branches: 1.12.2;
Updates so that mknative gets the right things.

- Disable symbol versioning (for now)
- Make sure that libiberty knows its being configured with a

- The CXX_* variables are no longer needed/used.
- LIB2FUNCS_EXTRA gets pulled in via LIB2ADD
- Get LIB1ASMFUNCS and LIB2ASMSRC
- MAYBE_USE_COLLECT2 got renamed to USE_COLLECT2 (but might not
be used)
- Get EXTRA_HEADERS so that we get generate the right paths for
CPPFLAGS
- Get some variables related to shared libgcc

Move libgcc3/*.mk to libgcc3/arch.

Update mknative-gcc.

also grab LIB2FUNCS_EXTRA for libgcc3 (old fix for m68000).

don't want auto-build.h anymore

we need config.h an another version of gthr-default.h

fix a typo in previous

libiberty/config.h needs to become per-arch.

fix a bug in previous - two $'s are bad

add another transform for libobjc3

- build "binutils" and "gcc" separately if USE_TOOLS_TOOLCHAIN is not set
to "yes".
- adjust dbsym/mdsetimage to look in the correct place for libbfd.
- new mknative-gcc based in toolchain/mknative

fetch experimental_headers, experimental_bits_headers, and ext_host_headers
to install install experimental/* and ext/opt_random.h.

fetch omp-device-properties.h and don't try to fetch sanitizer

make mknative-gcc.old for GCC 9. begin to update mknative-gcc for GCC 10.

more consolidation and properly condition all variables like previously.

consolidate a bunch of libstdc++ variable collection.

oops, pull out the value of pstl_headers.

pass down earm* not earmv5* to mknative-gcc.

disable fetching stuff from libsanitizer for now. it needs libstdc++
to build in mknative using gcc makefiles, and our locale changes break
the "normal" build of this.

make sure MKNATIVE_TARGET is always set. since mknative-gcc doesn't
care about the version any more (we keep two versions for gcc/gcc.old)
simply set it to "gcc".
