* | Fixes for libstdcxx-verbose option tristateNorbert Lange2022-07-111-1/+0
| | | | | | | | | | | | | | | | Make it proper "tristate" by not specifying the option. The config GCC_4_8_or_later was removed with cc6b7fad46f5cb3d84, so dont use it.
* | Allow libsanitizer on architectures that support itChris Packham2022-07-119-2/+20
| | | | | | | | | | | | | | | | | | | | | | | | libsanitizer is only supported on selected architectures. Add ARCH_SUPPORTS_LIBSANITIZER and have architectures select this option based on the list of supported configurations from GCC's libsanitizer/configure.tgt. Support for mips64 was added in GCC12 so this is an additional condition for the mips architecture. Fixes #1733 Signed-off-by: Chris Packham <judge.packham@gmail.com>
* | newlib: fix conflicting configure optionsChen Tao2022-06-281-0/+24
| | | | | | | | | | | | | | | | | | | | Configuring the newlib with "--enable-newlib-nano-formatted-io" and "--enable-newlib-io-pos-args" would cause built GCC cannot compile some IO functions like "std::cout". And I added additional notes at Nano Formatted I/O config. Signed-off-by: Chen Tao <t.clydechen@gmail.com>
* | kconfig: modify rules for multilibs configurationChen Tao2022-06-282-6/+10
| | | | | | | | | | | | | | | | | | fix conflict options when compiling multilibs on ARM based architecture. "--with-arch", "--with-cpu", "--with-fpu", "--with-float", and "--with-mode" should not be configured with "--with-multilib-list=list" when configuring multilibs.

* | glibc: configure adding debug symbols in glibc buildGuillermo E. Martinez2022-06-211-0/+7
|/ | | | | | | | | | After building the cross toolchain and compile a simple C program, objdump reports debug information even though -g modifier was not used. These debug segments are in glibc library and CRT files. So a new config entry: CT_GLIBC_ENABLE_DEBUG was added to control when we want to add debug information to glibc, by default is enabled.

* gcc: Disable zstd for canadian buildsChris Packham2022-05-311-2/+1
| | | | | | | | | | We don't currently bundle zstd so when performing a canadian build we need to tell GCC not to enable zstd support for lto otherwise it might decide to enable it based on the package being installed on the build machine. Fixes #1718 Signed-off-by: Chris Packham <judge.packham@gmail.com>
* glibc: rework GLIBC_ENABLE_WERRORChris Packham2022-05-311-5/+6
| | | | | | | | | | Use `depends on` conditions to enable/disable building glibc with -Werror. Using `depends on` instead of `default if` means that when the GCC/GLIBC selection changes GLIBC_ENABLE_WERROR will automatically become n.

* glibc: Reinstate support for the bundled portsChris Packham2022-05-181-0/+9
| | | | | | | | | | | Commit 6d5227b6 ("Remove obsolete glibc 2.12.1") removed supports for the separate glibc-ports but also removed GLIBC_USE_PORTS_ADDON. Glibc versions up to 2.20 bundled support from some architectures in the ports directory so GLIBC_USE_PORTS_ADDON is required to support these older glibc versions.

* Remove obsolete bionic/android supportChris Packham2022-05-105-132/+0

* glibc: Enable -Werror for more combinations of GCC/GLIBCChris Packham2022-05-011-2/+8
| | | | | | | | | | | Newer GCC versions trigger warnings on older GLIBC versions. GLIBC 2.29 is warning free with GCC9. GLIBC 2.31 is warning free with GCC10. GLIBC 2.34 is warning free with GCC11. Add milestones for 2.31 and 2.34 and use those to set the default value for GLIBC_ENABLE_WERROR based on the GCC version. Signed-off-by: Chris Packham <judge.packham@gmail.com>

* bionic: mark bionic/android-ndk as obsoleteChris Packham2022-02-231-0/+1
| | | | | | | | | | Support for bionic was dropped by GCC some time ago. There are patches for older GCC versions but those are difficult to maintain and the version of the android-ndk they support is of little use. Mark all of the existing bionic support as obsolete so it can be removed after the next release. Signed-off-by: Chris Packham <judge.packham@gmail.com>

| * sparc-leon: restrict to GDB9Alexey Neyman2022-02-111-0/+7
| | | | | | | | | | | | | | | | | | | | Starting with GDB10, it requires support for std::future<> in the compiler. Such support has not been available on some architectures until GCC9 (see PR 64735). I haven't determined the exact list of affected architectures, so decided to make it a broad dependency: for GDB10+, you need GCC9+. Signed-off-by: Alexey Neyman <stilor@att.net>

This concludes the glorious history of the original uClibc (non-NG) with lots of kludges removed. There was a choice here, whether to call the resulting libc "uClibc" or "uClibc-ng". I opted in favor of giving uClibc-ng the recognition it deserves, although it had some ripple effect in the ct-ng code. Signed-off-by: Alexey Neyman <stilor@att.net>

| | | | | | | | | | | | Now that we have a 2-pass build it is no longer necessary to disable -Werror in glibc. This partially reverts commits 6ca5f91f ("Disable -Werror for GLIBC for all ARCH for GCC11."), 215432d3 ("config/libc: Extend glibc 2.32 workaround to include sparc") and 645ee124 ("glibc: Don't build with -Werror for powerpc64+glibc-2.32").

* gcc: Build static libgcc in core_pass1Chris Packham2022-01-126-12/+5
| | | | | | | | | | | | | | | | | | Per https://github.com/crosstool-ng/crosstool-ng/issues/808 build static libgcc in the first pass which lets us skip the second one. Building mingw-w64 requires header files in order to build C++ support so mingw builds core pass 2. This could probably be cleaned up by splitting libc_start_files into a separate libc_header step. But for now having core 2 for mingw-w64 and core 1 for the other libcs will have to do. Anything that previously selected CC_CORE_PASSES_NEEDED now selects CC_CORE_PASS_1_NEEDED. The same goes for CC_CORE_PASS_2_NEEDED with the exception of mingw-w64. Fixes #808 Fixes #217 Signed-off-by: Chris Packham <judge.packham@gmail.com>

* cc/gcc: Add options for zstd usageChris Packham2021-08-291-0/+19
| | | | | | | | | | | | GCC can support using zstd compression for LTO object files. By default GCC's configure will enable this if libzstd is installed on the machine building the toolchain.

| | | | | | | | | | | | | | | | | In GDB 10.x gdbserver was promoted to the top-level folder, see https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=919adfe8409211c726c1d05b47ca59890ee648f1 Which means it is no longer a subfolder in "gdb" and so we have to build gdbserver now exactly in the same way as normal native GDB. One interesting detail is gdbserver doesn't need to deal with target description in .xml so it doesn't depend on libexpat on target, thus we need to move libexpat explicit selection from do_gdb_backend() to its callers when building native [full] gdb as well as cross-gdb for the host.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC11 somehow has different set of multilibs on SH arch than what GCC10 had. In particular: $ gcc10 -print-multi-lib | sed -r -e 's/@/ -/g;' .; mb; -mb m2; -m2 m2e; -m2e m4; -m4 m4-single; -m4-single m4-single-only; -m4-single-only mb/m2; -mb -m2 mb/m2e; -mb -m2e mb/m4; -mb -m4 mb/m4-single; -mb -m4-single mb/m4-single-only; -mb -m4-single-only mb/m2a; -mb -m2a mb/m2a-single; -mb -m2a-single $ gcc11 -print-multi-lib | sed -r -e 's/@/ -/g;' .; mb; -mb m2; -m2 m2e; -m2e m4; -m4 m4-single; -m4-single m4-single-only; -m4-single-only mb/m1; -mb -m1 mb/m2; -mb -m2 mb/m2e; -mb -m2e mb/m4; -mb -m4 mb/m4-single; -mb -m4-single mb/m4-single-only; -mb -m4-single-only mb/m2a; -mb -m2a mb/m2a-single; -mb -m2a-single mb/m1 fails to build libgcc as libgcc uses opcodes that were not available in SH-1: libgcc/config/sh/lib1funcs.S uses 'bt/s' and 'dt' instructions that, according to https://antime.kapsi.fi/sega/files/h12p0.pdf become available in the SH-2 only. So I removed mb/m1 from the multilibs fog GCC11 and SH arch. Another option would be to try not to build libgcc for this combination of the gcc version and archichecture, but I thought this fix would be more robust.
