2021-06-07gcc: Add CT_CC_GCC_TM_CLONE_REGISTRY configStephanos Ioannidis1-0/+7
This commit adds a new gcc config `CT_CC_GCC_TM_CLONE_REGISTRY` that enables the GCC transactional memory clone registry feature for libgcc. Note that the gcc option to control this feature is only available in gcc 10 and above. (see gcc commit 5a4602805eb3ebddbc935b102481e63bffc7c5e6) Signed-off-by: Stephanos Ioannidis <root@stephanos.io>
2021-05-11glibc: --enable-obsolete-rpc has been removed as of 2.32Chris Packham1-1/+1
Make --enable-obsolete-rpc conditional on !GLIBC_2_32_or_later as it's been removed from that version on. Fixes: #1505 Fixes: commit 1ee44ab5 ("glibc: --enable-obsolete-rpc has been removed as of 2.32") Signed-off-by: Chris Packham <judge.packham@gmail.com>
2021-05-11alpha: Support 64-bit onlyChris Packham1-2/+2
Alpha is a 64-bit only arch. The menu options only allowed 32 bitness to be selected. This was harmless but confusing, update the config to specify 64-bit only. Fixes: #1506 Signed-off-by: Chris Packham <judge.packham@gmail.com>
2021-05-05Remove m1 from multilibs for GCC11 on SH arch.spaun20021-0/+1
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.

2021-05-05Disable -Werror for GLIBC for all ARCH for GCC11.spaun20021-2/+3
This change replicates what GLIBC 2.23 has in the string/rawmemchr.c: // #if __GNUC_PREREQ (11, 0) // /* Likewise GCC 11, with a different warning option. */ // DIAG_IGNORE_NEEDS_COMMENT (11, "-Wstringop-overread"); // #endif With -Werror multiple platforms failing on the string/rawmemchr.c:40 line.

2021-04-15newlib-nano: Add option to copy libs into targetKumar Gala1-0/+11
Add an option that will install a copy of newlib-nano lib*.a file in the target dir but renamed with a nano.a suffix (eg: libc_nano.a) as some default nano.spec files from newlib expect this setup. Additionally the newlib-nano version of newlib.h will get copied to include/newlib-nano/newlib.h. Signed-off-by: Kumar Gala <kumar.gala@linaro.org>

2021-02-02config/cc/gcc.in: Fix typo CC_GCC_DEC_FLOAT -> CC_GCC_DEC_FLOATSChris Packham1-3/+3
This has gone unnoticed for a while, it looks like all configurations have probably been using the default floats behaviour. Newer kconfig tells us the default value is not in the choice so lets fix this in preparation. Signed-off-by: Chris Packham <judge.packham@gmail.com>

Use LIBC_PICOLIBC_CXA_ATEXIT to keep this name in the same 'namespace' as the other picolibc config names. Enable retargetable locking by default. This allows the few locks in picolibc to be implemented by the execution environment, rather than disabling the locking code. Signed-off-by: Keith Packard <keithp@keithp.com>

2020-10-13Clarify tree layout of local patches directoryBagas Sanjaya1-2/+4
Currently the help for LOCAL_PATCH_DIR did not specify the tree layout of custom patches directory. This commit adds such explanation. For example, the bundled patches for GCC are placed under packages/gcc/<gcc-version>, thus custom (local) GCC patches should be placed under $LOCAL_PATCH_DIR/gcc/<gcc-version>.
