toolchain-wrapper: use -ffp-contract=off on MIPS Xburst for gcc >= 4.6

2018-04-08T14:54:49+00:00

Since gcc 4.6, GCC deprecated -mfused-madd, -ffp-contract=off should be used for the Xburst workaround. Tested with the MIPS Sourcery 2011.03 toolchain (based on gcc 4.5), the toolchain wrapper uses -mno-fused-madd, as expected: $ BR2_DEBUG_WRAPPER=2 ./output/host/bin/mips-linux-gnu-gcc -o toto toto.c Toolchain wrapper executing: '/home/thomas/toolchains/mips-2011.03/bin/mips-linux-gnu-gcc' '--sysroot' '/home/thomas/projets/buildroot/output/host/mipsel-buildroot-linux-gnu/sysroot' '-mabi=32' '-msoft-float' '-mno-fused-madd' '-EL' '-march=mips32r2' '-o' 'toto' 'toto.c' And with the MIPS Sourcery 2012.09 toolchain (based on gcc 4.7), the toolchain wrapper uses -ffp-contract=off, as expected: $ BR2_DEBUG_WRAPPER=2 ./output/host/bin/mips-linux-gnu-gcc -o toto toto.c Toolchain wrapper executing: '/home/thomas/toolchains/mips-2012.09/bin/mips-linux-gnu-gcc' '--sysroot' '/home/thomas/projets/buildroot/output/host/mipsel-buildroot-linux-gnu/sysroot' '-mabi=32' '-msoft-float' '-ffp-contract=off' '-EL' '-march=mips32r2' '-o' 'toto' 'toto.c' Fixes the ci20_defconfig build: https://gitlab.com/buildroot.org/buildroot/-/jobs/60303132 Signed-off-by: Waldemar Brodkorb [Thomas: rework to continue supporting pre-gcc-4.6 toolchains, extend the commit log after doing more testing.] Signed-off-by: Thomas Petazzoni Reviewed-by: Ezequiel Garcia Signed-off-by: Thomas Petazzoni (cherry picked from commit 5e58509bfe497c5e85db58f8213b0a44ac79dd3f) Signed-off-by: Peter Korsgaard

toolchain: fix detection of SSP support

2018-04-06T17:55:25+00:00

GCC issues a warning message if -fstack-protector is passed but SSP is not available, so in order to force the compilation to fail we must also pass -Werror. All external toolchains were verified. The only one whose configuration incorrectly selected BR2_TOOLCHAIN_HAS_SSP was CodeSourcery NIOSII.

toolchain: limit musl/kernel headers conflict workaround

2018-03-30T16:42:27+00:00

The musl/kernel headers workaround was added in commit 196932cd91 (toolchain: workaround musl/kernel headers conflict) to fix definition collisions in networking related headers between musl headers and kernel headers. Kernel headers from version 4.15 and newer do not need this workaround anymore since kernel commit c0bace798436bc (uapi libc compat: add fallback for unsupported libcs). The C library does not have to define the __GLIBC__ macro to make the __UAPI_DEF_* macros effective. Updated the comment to accordingly. Tested with the xl2tp package. This package fails to build with older kernel headers without the workaround (struct in_pktinfo redefinition, among others). With 4.15 headers, xl2tp builds fine with this patch applied. That is, no workaround needed.

toolchain/toolchain-external: libatomic should also be copied for musl toolchains

2018-01-17T21:37:59+00:00

libatomic, like libgcc_s, is provided by gcc, so there is no reason to copy it over only for the glibc and uclibc cases, it should also be copied for the musl case. Without this, a program linked with libatomic on a musl system will fail to run due to the missing library. Signed-off-by: Thomas Petazzoni Reviewed-by: "Yann E.

toolchain: m68k coldfire is also affected by gcc bug 64735

2018-01-07T20:56:59+00:00

Verified experimentally by using exception_ptr with m68k_cf5208 and looking at the value of ATOMIC_INT_LOCK_FREE. ATOMIC_INT_LOCK_FREE=1, so the issue is present. Also verified that gcc 7.x fixed it also for cf5208. Signed-off-by: Jan Heylen Signed-off-by: Thomas Petazzoni

toolchain: post-pone evaluation of TOOLCHAIN_EXTERNAL_BIN

2017-12-31T17:24:17+00:00

The upcoming per-package SDK functionality is heavily based on the fact that HOST_DIR, STAGING_DIR and TARGET_DIR are evaluated during the configure/build/install steps of the packages. Therefore, any evaluation-during-assignment using := is going to cause problems, and need to be turned into evaluation-during-use using =. This patch fix up one such instance in the external toolchain code. This change is independent from the per-package SDK functionality, and could be applied separately.
