In the current clang crtfastmath.o is only linked when -ffast-math/-funsafe-math-optimizations passed. It can lead to performance issues, when using only -Ofast without explicit -ffast-math (I faced with it). My patch fixes inconsistency with gcc behaviour and also introduces few tests on it.

2013-12-23---Merging r196453Bill Wendling2-1/+13
Parse: Recover better from bad definitions with base specifiers We would skip until the next comma, hoping good things whould lie there, however this would fail when we have such things as this: struct A {}; template <typename> struct D; template <> struct D<C> : B, A::D; Once this happens, we would believe that D with a nested namespace specifier of A was a variable that was being declared. We would go on to complain that there was an extraneous 'template <>' on their variable declaration. Crashes would happen when 'A' gets defined as 'enum class A {}' as various asserts would fire. Instead, we should skip up until the semicolon if we see that we are in the middle of a definition and the current token is a ':' This fixes PR17084. llvm-svn: 197905

Implement a -Wkeyword-compat extension warning to diagnose those cases. The warning is on by default but will generally be ignored in system headers. It can however be enabled globally to aid standards conformance testing. This also changes the __uptr keyword avoidance from r195710 to no longer special-case system headers, bringing it in line with other similar workarounds in clang. Implementation returns bool for symmetry with token annotation functions. Some examples: warning: keyword '__is_pod' will be treated as an identifier for the remainder of the translation unit [-Wkeyword-compat] struct __is_pod warning: keyword '__uptr' will be treated as an identifier here [-Wkeyword-compat] union w *__uptr; ------------------------------------------------------------------------ llvm-svn: 197359

To address this, we change the way we model number mangling: always mangle as-if our number is an int64_t. This should result in correct results when we have large unsigned numbers. N.B. Bizarrely, things that are 32-bit displacements like vbptr offsets are mangled as-if they are unsigned 32-bit numbers. This is a pretty egregious waste of space, it would be a 4x savings if we could mangle it like a signed 32-bit number. Instead, we explicitly cast these displacements to uint32_t and let the mangler proceed. ------------------------------------------------------------------------ llvm-svn: 196878

This is another regression fixed by reverting r189090. In this case, the problem is not live variables but the approach that was taken in r189090. This regression was caused by explicitly binding "true" to the condition when we take the true branch. Normally that's okay, but in this case we're planning to reuse that condition as the value of the expression. ------------------------------------------------------------------------ llvm-svn: 196796

The original patch introduced regressions (see the added live-variables.* tests). The patch depends on the correctness of live variable analyses, which are not computed correctly. I've opened PR18159 to track the proper resolution to this problem. The patch was a stepping block to r189746. This is why part of the patch reverts temporary destructor tests that started crashing. The temporary destructors feature is disabled by default. ------------------------------------------------------------------------ llvm-svn: 196795
