2014-08-15gcc: backport patch affecting Linux kernel buildsPeter A. Bigot1
A long-standing bug in gcc turns out to cause problems with unpatched Linux versions due to improved optimization enabled by gcc 4.9. The upstream fix missed the gcc-4.9.1 cut-off. It's also been applied upstream to the 4.8 branch so is being added for OE's 4.8 as well. Signed-off-by: Peter A.

2014-08-15gcc: remove inappropriate patchPeter A. Bigot1
0037-gcc-4.8-PR56797.patch was originally added as an OE backport during 4.8.0. Upstream merged it in 4.8.1, and it was present in 4.9.0. The original patch still applies to 4.9.1 (and presumably 4.8.2), but now is modifying store_multiple_sequence instead of load_multiple_sequence (the two functions are nearly identical). It may or may not be necessary in store_multiple_sequence, but absent a bug report upstream supporting its application in this case, or a least an updated comment and upstream status in the patch, I think this patch should be dropped.

2014-01-31gcc: Include patch scheduled for GCC 4.8.3 to fix epilogue on ARMHolger Hans Peter Freyther1
GCC 4.8.0, 4.8.1 and 4.8.2 can generate broken epilogues for the ABI used by the kernel. Apply the patch that is included for GCC 4.8.3 from http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58854. The issue was found on Yocto/Dora and the patch should be backported to this branch. A kernel built with Dora's GCC 4.8.1 misbehaved on: while true; do (for i in `seq 1 100`; do echo "Log message... $RANDOM"; done) | logger; done busybox's syslogd would from time to read a huge negative value and then exit, strace would get stuck waiting on a syscall. After this patch it appears to work better. Signed-off-by: Holger Hans Peter Freyther <holger@moiji-mobile.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

2013-09-22gcc-target: Fix libatomic dependency tracking issuesRichard Purdie1
The --enable-dependency-tracking option was added to workaround build issues in libatomic. This fixes that build problem properly and removes the flag since the dependency tracking code appears to be full of races which are much deeper and harder to fix. As per the automake manual, dependency tracking is only useful and worth the build performance cost if you are doing more than one compile of the same source code which in most cases we are not so this is a good thing anyway.

2013-07-25gcc-4.8: fix compiling GCC when /usr/lib/libstdc++.so is presentJonathan Liu1
libtool is picking up libstdc++.so from /usr/lib when trying to link libasan due to libstdc++.la containing libdir="/usr/lib". If compiling for x86 and the host has 64-bit /usr/lib/libstdc++.so, the compilation fails linking libasan with: /usr/lib/libstdc++.so: could not read symbols: File in wrong format To resolve this, patch libtool to look for the library in the path the .la is contained in rather than use the libdir which usually points to a host path.

2013-06-25gcc: When cross compiling a target gcc, target flags may be used on the hostMark Hatle1
The original fix worked some of the time, but not on all machines. Fix this by applying the change in a different way. Following the example of the existing BUILD_CFLAGS. Below is the commit message from the original change to help explain why this is needed: Configure identifies a number of warning flags (WARN_CFLAGS and WARN_CXXFLAGS) from the $CC value. The cross compiler may be different from the host compiler and may not support the same set of flags. This leads to problems such as: cc1plus: error: unrecognized command line option "-Wno-narrowing" cc1plus: error: unrecognized command line option "-Wno-overlength-strings" Work around this problem by removing the warning flags from the BUILD_CXXFLAGS value, in a way similar to the BUILD_CFLAGS.
