toolchain: gcc: backport inline subword atomic support for riscv

2023-06-11T15:09:06Z

RISC-V has no support for subword atomic operations; code currently generates libatomic library calls. This patch changes the default behavior to fast inline subword atomic calls that do not require libatomic. Signed-off-by: Tianling Shen

toolchain: gcc: backport patch for gcc 13 fixing access path analysis

2023-05-05T13:46:38Z

While improving access path analysis a typo happened. Now it can happen that gcc misscompiles. The patch is fixing the issue. However, also other gcc versions 10.2+ are affected. They also should be bumped or the fix should be backported. For more bug information have a look at: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=109585 Signed-off-by: Nick Hainke

toolchain/gcc: enable zstd support

2023-03-17T01:08:25Z

LTO object files will now be compressed using zstd. Compressing debug sections with zstd will have to wait for GCC 13, which adds support for -gz=zstd. NOTE: wiping the ccache is strongly recommended, not doing so might yield build error later on: "lto1: internal compiler error: original not compressed with zstd" Signed-off-by: Andre Heider

toolchain: remove installing twice in the "initial" subdir

2023-02-19T18:44:39Z

This was apparently introduced to recreate the toolchain (wipe staging_dir/toolchain*, but keep build_dir/toolchain*, followed by a `make toolchain/compile`). But it leaves leftovers and causes re-links to happen at src_install phase, because of the changed paths, possibly adding yet another source of issues. With the prior commits removing various hacks related to the "initial" folder we can remove installing it twice altogether. The recreated toolchain is exactly the same as before.

toolchain/musl: remove libgcc_initial hack

2023-02-19T18:44:39Z

This reverts r15599 [0]. This was added to fix an uclibc rebuild issue, but since uclibc isn't supported anymore [Fixes:] this can be removed.

toolchain/gcc: remove glibc libgcc_eh hack

2023-02-19T18:44:39Z

A modern glibc only links against libgcc_eh for its tests or when building it static, which doesn't happen here. Reverts a hunk of: a3edea1b "add support for alternative C libraries..." Signed-off-by: Andre Heider

toolchain/gcc: clean up CFLAGS

2023-02-09T01:53:35Z

Instead of having two different ways to pass flags to the gcc build process, add them as configure args, which is a reliable way to let gcc pass them around to its various pieces. Also add CXXFLAGS, since gcc started to use c++ for itself recently (~10 years ago now). Signed-off-by: Andre Heider
