tools: Consolidate types.h

2014-05-01T19:22:39Z

Combine all definitions into a common tools/include/linux/types.h and kill the wild growth elsewhere. Move DECLARE_BITMAP to its proper bitmap.h header.

tools: Unify export.h

2014-05-01T19:18:17Z

So tools/ has been growing three, at a different stage of their development export.h headers and so we should unite into one. Add tools/include/ to the include path of virtio and liblockdep to pick the shared header now.

perf tools: Fix strict alias issue for find_first_bit

2014-02-28T13:39:40Z

When compiling perf tool code with gcc 4.4.7 I'm getting following error: CC util/session.o cc1: warnings being treated as errors util/session.c: In function ‘perf_session_deliver_event’: tools/perf/util/include/linux/bitops.h:109: error: dereferencing pointer ‘p’ does break strict-aliasing rules tools/perf/util/include/linux/bitops.h:101: error: dereferencing pointer ‘p’ does break strict-aliasing rules util/session.c:697: note: initialized from here tools/perf/util/include/linux/bitops.h:101: note: initialized from here make[1]: *** [util/session.o] Error 1 make: *** [util/session.o] Error 2 The aliased types here are u64 and unsigned long pointers, which is safe for the find_first_bit processing. This error shows up for me only for gcc 4.4 on 32bit x86, even for -Wstrict-aliasing=3, while newer gcc are quiet and scream here for -Wstrict-aliasing={2,1}. Looks like newer gcc changed the rules for strict alias warnings. The gcc documentation offers workaround for valid aliasing by using __may_alias__ attribute: http://gcc.gnu.org/onlinedocs/gcc-4.4.0/gcc/Type-Attributes.html Using this workaround for the find_first_bit function.

perf tools: Drop prefetch.h

2014-02-18T12:34:49Z

This was needed at the time before e66eed651fd1 ("list: remove prefetching from regular list iterators") where the list iterators did prefetch elements. This turned out to be counter-productive and hurt performance and they were removed. Which makes the prefetch.h header unused so drop it.

perf tools: Fix include for non x86 architectures

2014-01-31T20:21:42Z

Commit 71ae8aac ("lib: introduce arch optimized hash library") added an include to for setting up an architecture specific fast hash. Since perf includes directly the non-uapi kernel header, it cannot find on non-x86 and thus prevents perf to be compiled on every architecture other than x86. The problem is the inclusion of in hash.h that results in the following error originating from util/evlist.c: fatal error: asm/hash.h: No such file or directory This commit simply adds an empty stub/file to fix the compile issue on non-x86 architectures. As perf does not use any of these new functions, it fixes the compilation and therefore seems to be the most appropriate solution to go with.
