gcc 4.9: backport gperf fixes

2016-05-14T22:05:12+00:00

gperf was being used in a way that generated files don't conform to the language standard. Backport the fix from upstream. This is required to build these GCC versions when the host compiler is GCC 6.

gcc: obey ldflags in the link of libgcc

Explicitly obey it, the way it should, rather than only relying on --with-linker-hash-style. (From OE-Core rev: 9095742d1468477baefe69098817f38a8d2dd750) Signed-off-by: Christopher Larson Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

gcc-5.3/gcc-4.9: -fdebug-prefix-map support to remap relative path

2016-03-30T11:01:29+00:00

For relative path in DWARF, -fdebug-prefix-map could not remap it, so translate to real path before mapping. [YOCTO #9305] (From OE-Core rev: e50d23c30cd8259941b25e336b11cd96e4f6cd31) Signed-off-by: Hongxu Jia Signed-off-by: Richard Purdie

gcc-5.3/gcc-4.9:Reuse -fdebug-prefix-map to replace -ffile-prefix-map

2016-03-20T23:12:31+00:00

The oe-core may use external toolchain for compiling, which did not support -ffile-prefix-map. Since we use -fdebug-prefix-map to do the same thing, so we could reuse it to replace -ffile-prefix-map.

gcc-5.3/gcc-4.9:replace build path with target path in FILE

2016-03-20T23:12:30+00:00

Similar -fdebug-prefix-map, add option -ffile-prefix-map to map one directory name (old) to another (new) in __FILE__, __BASE_FILE__and __builtin_FILE (). With this patch, it fixes build path issue which caused by __FILE__. We do not need to use relative path to compile any more.

gcc: fix hidden weak symbols by removing buggy gcc patch

2016-01-30T11:37:01+00:00

We are noticing the presence of the following patch in various openembedded gcc versions: 0024-PR-target-32219.patch However, contrarily to its "Backport" status, that patch is not upstream in gcc, and it breaks handling of start/stop automatic weak hidden symbols we use in lttng-ust. We are only experiencing problems on the various openembedded compilers, but on no other distro (with same compiler versions), which led us to suspect a buggy distro-specific gcc patch. We've been testing with openembedded gcc-4.9.2-r0. Rebuilding the gcc compiler with this patch removed fixes the lttng-ust issue.
