gcc: fix build of gcc 6.x on Microblaze

2016-05-17T06:42:56+00:00

Due to patch 840-microblaze-enable-dwarf-eh-support.patch, gcc 6.x does not build: ../../gcc/config/microblaze/microblaze.c: In function 'void microblaze_expand_epilogue()': ../../gcc/config/microblaze/microblaze.c:3046: error: 'gen_rtx_raw_REG' was not declared in this scope This patch was originally added to gcc 4.9 to make it capable of building glibc. However, this is no longer needed with gcc 6.x, which builds glibc just fine. Signed-off-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard

gcc: fix ccache hash of patches in BR2_GLOBAL_PATCH_DIR

2016-04-18T21:02:34+00:00

In commit f4682cf933, a hash of the patches applied to gcc was created to make sure that ccache can properly detect when the toolchain has changed. The patches applied to gcc consist of the buildroot patches in package/gcc, but also potentially patches in BR2_GLOBAL_PATCH_DIR. However, the path to the patches in BR2_GLOBAL_PATCH_DIR was corrected incorrectly, because it misses a /. So instead of: $(BR2_GLOBAL_PATCH_DIR)/gcc-initial/*.patch it would look for $(BR2_GLOBAL_PATCH_DIR)gcc-initial/*.patch In other words, if BR2_GLOBAL_PATCH_DIR doesn't end with /, the patches in BR2_GLOBAL_PATCH_DIR are not taken into account in the ccache hash.

gcc: fix libsanitizer build with _FILE_OFFSET_BITS=64

2016-03-24T21:55:57+00:00

After the commit f67a4f50e2ace3a2 "gcc: preserve CXXFLAGS_FOR_TARGET" target CFLAGS are passed to all libraries bundled with gcc. This breaks libsanitizer on gcc-4.9.x when building with _FILE_OFFSET_BITS=64: error: size of array ‘assertion_failed__837’ is negative ... libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cc:837:1: note: in expansion of macro ‘CHECK_SIZE_AND_OFFSET’ CHECK_SIZE_AND_OFFSET(dirent, d_ino); This issue is fixed in the libsanitizer mainline and in gcc-5.x. There's no issue with gcc-4.8.x and earlier.
