* Fixes for libstdcxx-verbose option tristateNorbert Lange2022-07-111-0/+2
| | | | | | | | 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 Packham2022-07-111-5/+5
| | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | Add GCC 12.1 https://gcc.gnu.org/gcc-12/ The following patches from GCC 11.3.0 are no longer needed: - 0005-arc-Update-ZOL-pattern.patch - 0006-arc-Update-u-maddhisi4-patterns.patch - 0007-arc-Fix-maddhisi-patterns.patch - 0008-Darwin-aarch64-Initial-support-for-the-self-host-dri.patch - 0009-libstdc-Check-for-TLS-support-on-mingw-cross-compile.patch One new patch is needed to avoid issues building sh-unknown-elf: - 0006-sh-Avoid-mb-m1-multilib-combination.patch It is also necessary to build all-build-libcpp. This target exists as far back as GCC 6 so has been done unconditionally.

* cc/gcc: Create liblto_plugin symbolic link with correct extensionJoel Holdsworth2022-05-111-4/+12
| | | | | | | | | | | | Previously, cc/gcc.sh assumed that liblto_plugin would always be installed with the ".so" file extension. However, this assumption is incorrect when the host machine is Windows (".dll") or MacOS (".dylib"). This patch corrects this issue by probing the file extension in similar fashion to the way adjacent code determines the file extension of executable binaries.

* cc/gcc: Remove -lstdc++ and -lm from gcc LDFLAGSJoel Holdsworth2022-05-111-24/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In Bryan Hundven's patch 1ad439907 from 2010, the author added -lstdc++ and -lm to the host gcc build's LDFLAGS, because at the time the linker did not correctly include these libraries causing the build to fail. In modern builds, this causes a problem for canadian gcc builds where the host machine is mingw32-w64 Windows. Within the gcc build there is the liblto_plugin module. On Windows this must be built as the "liblto_plugin.dll" dynamic library. However, libtool cannot produce a dynamic library unless every library dependency is also a dynamic library, and falls back to producing a libstdc++.a static library. liblto_plugin does not require libstdc++ - it does not contain any C++ code, and the dependency would usually be elided by the linker. Unfortunately, in this case, crosstool-ng will never build a libstdc++.dll dynamic library - only a libstdc++.a static library. Therefore, there will never be a dynamic library version of stdc++ for libtool to load and then discard. This patch corrects the issue by removing "-lstdc++" from LDFLAGS, because modern versions of gcc are able to correctly include libstdc++ where necessary. It also remove "-lm" for similar reasons.

* gcc: Build static libgcc in core_pass1Chris Packham2022-01-121-0/+2
| | | | | | | | | | | | | | | | | | 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>

| * gcc: Fix canadian cross building on older hostsAlexey Brodkin2021-09-061-13/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC 11+ requires compiler being used to support C++11 standard [1]. And while GCC starting from 6.x has C++11 support enabled by default [2], older versions need to be forced to implement it with "-std=gnu++11" and luckily GCC's build-system takes care of that: 1. For ${host} compiler - [1] 2. For ${build} compiler - [3, 4] In a nutshell the configure script tries a couple of options and the one which helps to build a test source gets appended to CXX (not CXXFLAGS!), so on say CentOS 7.x with GCC 4.8.5 during cross-compilation of GCC CXX="x86_64-build_pc-linux-gnu-g++ -std=gnu++11". And all is good. But in case of canadian cross due to [5] we for some reason* force set CXX_FOR_BUILD with just a compiler name, effectively overriding all the magic done by GCC's internals described above. This leads to a compilation failures like that: ------------------------------------->8---------------------------------- [ALL ] In file included from /usr/include/c++/4.8.2/type_traits:35:0, [ALL ] from .../HOST-x86_64-apple-darwin14/arc-gcc11-elf/src/gcc/gcc/system.h:244, [ALL ] from .../HOST-x86_64-apple-darwin14/arc-gcc11-elf/src/gcc/gcc/gengtype.c:26: [ERROR] /usr/include/c++/4.8.2/bits/c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support is currently experimental, and must be enabled with the -std=c++11 or -std=gnu++11 compiler options. [ALL ] #error This file requires compiler and library support for the ^ ------------------------------------->8---------------------------------- * my guess that [5] was done because back in the day indeed we used to have "--build=${CT_BUILD} --host=${CT_HOST}" in do_cc_core(). But now after [6] this is no longer necessary as we use "--build=${CT_BUILD} --host=${CT_BUILD}" and all is safe and clean. So yet another old quirk goes away - hooray!

* | gcc: Don't mess with --with-host-libstdcxx if recent GCC (6+) is usedAlexey Brodkin2021-09-071-8/+12
|/ | | | | | | | | | | | | | | | | | | | | "--with-host-libstdcxx" option was removed in GCC 6.x, see [1] because of [2]. So it makes no sense to use it with later GCC versions. Frankly I don't like that implementation with yet another set of "if XXX", but since we still support GCC down to 4.8.5 what else we may do? Well, technically we may keep using things as they are now, because surprisingly GCC's configure script doesn't mind accepting meaningless options, but as a person who's looking at differences between various builds and drill-down to peculiarities of various config options, I'd prefer to not pollute configure with garbage. But for all the rest... well, it works now and maybe nodody else cares.

* cc/gcc: Add options for zstd usageChris Packham2021-08-291-0/+5
| | | | | | | | | | | | 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. This may be undesirable if the toolchain is to be used on a different machine. Add an option to control zstd usage and set the default to the same as the current behaviour (i.e. auto).

| * gcc: Allow setting custom target CXXFLAGSStephanos Ioannidis2021-06-071-3/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds two additional arguments (`cxxflags_for_target` and `extra_cxxflags_for_target`) for the gcc backend build function that can be used to specify custom target CXXFLAGS. By default, the target CXXFLAGS is set to the target CFLAGS. When `cxxflags_for_target` is specified however, it overrides that behaviour and allows setting different target CXXFLAGS from the target CFLAGS. The `extra_cxxflags_for_target` argument can be used to specify the extra target CXXFLAGS to be appended to the target CXXFLAGS. This is useful when it is necessary to append CXX-specific flags to the existing CFLAGS to be used as the target CXXFLAGS. A useful application of this is building full and nano versions of libstdc++ with different target CXXFLAGS as necessitated by `nano.specs`. Signed-off-by: Stephanos Ioannidis <root@stephanos.io>
| * gcc: Assume '-O2' by default for building gcc target librariesStephanos Ioannidis2021-06-071-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The gcc target libraries (e.g. libstdc++) are currently built without any optimisation flag when `CT_CC_GCC_ENABLE_TARGET_OPTSPACE` is not enabled and default to `-O0` unless user explicitly specifies an optimisation flag. This commit updates the gcc build script to assume `-O2` for building target libraries unless user provides a different optimisation flag. Note also that this is the default behaviour for gcc when C[XX]FLAGS_FOR_TARGET is not overridden. Signed-off-by: Stephanos Ioannidis <root@stephanos.io>
