2016-07-14tools: Make "__always_inline" just "inline" on AndroidArnaldo Carvalho de Melo1-0/+11
As the gcc there is producing tons of: "warning: always_inline function might not be inlinable" At least on android-ndk-r12/platforms/android-24/arch-arm, so, for the time being, use this big hammer.

2015-10-13tools include: Fix strict-aliasing rules breakageJiri Olsa1-8/+24
Vinson reported build breakage with gcc 4.4 due to strict-aliasing. CC util/annotate.o cc1: warnings being treated as errors util/annotate.c: In function ‘disasm__purge’: linux-next/tools/include/linux/compiler.h:66: error: dereferencing pointer ‘res.41’ does break strict-aliasing rules The reason is READ_ONCE/WRITE_ONCE code we took from kernel sources. They intentionaly break aliasing rules. While this is ok for kernel because it's built with -fno-strict-aliasing, it breaks perf which is build with -Wstrict-aliasing=3. Using extra __may_alias__ type to allow aliasing in this case.

2015-05-08perf tools: Move barrier() definition to tools/include/linux/compiler.hArnaldo Carvalho de Melo1-0/+4
To make it generally accessible by other tools/ projects, also will be used in the tools/arch/*/include/asm/barrier.h files that are being introduced now.
