Summary --profile differences between Linux and Android

Due to using two profilers, our --profile output is different on each platform: Android - SvgCubics [ perf record: Captured and wrote 6.210 MB /data/perf.data (~271321 samples) ] 59.49% SignalSender libm.so [.] 0x1169c 8.66% SignalSender [kernel] [k] 0xc004fa50 7.10% SignalSender libDumpRenderTree.so [.] WebCore::PathTraversalState::cubicBezierTo(WebCore::FloatPoint const&, WebCore::FloatPoint const&, WebCore::FloatPoint const&) 5.80% SignalSender libDumpRenderTree.so [.] WebCore::CubicBezier::split(WebCore::CubicBezier&, WebCore::CubicBezier&) const 4.45% SignalSender libDumpRenderTree.so [.] WebCore::distanceLine(WebCore::FloatPoint const&, WebCore::FloatPoint const&) 2.57% SignalSender libc.so [.] 0x1fce0 1.41% SignalSender [unknown] [.] 0x6c12764c 0.94% SignalSender libDumpRenderTree.so [.] 0x181f90 0.21% SignalSender libDumpRenderTree.so [.] SkPath::RawIter::next(SkPoint*) 0.20% SignalSender libDumpRenderTree.so [.] WebCore::convertPathPoints(WebCore::FloatPoint*, SkPoint const*, int) Linux - SvgCubics Finished: 1.381556 s 56 47.9% 47.9% 56 47.9% WebCore::PathTraversalState::cubicBezierTo 3 2.6% 50.4% 3 2.6% 00007fba7a9055e2 3 2.6% 53.0% 3 2.6% __access 3 2.6% 55.6% 3 2.6% __libc_free 2 1.7% 57.3% 2 1.7% 00007fba7a905417 2 1.7% 59.0% 2 1.7% WebCore::Path::apply 2 1.7% 60.7% 2 1.7% WebCore::SVGResourcesCache::cachedResourcesForRenderObject 2 1.7% 62.4% 2 1.7% WebCore::StyleResolver::collectMatchingRules 2 1.7% 64.1% 2 1.7% __libc_malloc 2 1.7% 65.8% 2 1.7% tcmalloc::FL_Push It is possible this is due to the platform, but

Yeah, one uses pprof, the other uses perf. I should make it possible to use perf on either. It's possible pprof could be made to work on Android too (but not until they use tcmalloc... which I don't think they do yet).

These both use perf by default now. :) *** This bug has been marked as a duplicate of bug 104971 ***
