When annotating "lines" starting with ":", clang-format would segfault.

David Tweed d505b24277 Initially forgotten-to-svn-add test case for r177279. 
llvm-svn: 177280
 2013-03-18 12:07:24 +00:00
David Tweed 5493feed25 The optimization a + (-0.0f) -> a was being misapplied to a + (+0.0f) in the vector case (because 
we weren't differntiating floating-point zeroinitializers from other zero-initializers)
which was causing problems for code relying upon a + (+0.0f) to, eg, flush denormals to
0. Make the scalar and vector cases have the same behaviour.

Unfortunately the previous fix for inserting waits for unordered
defines wasn't sufficient, cause it's possible that even ordered
defines are only partially used (or not used at all).

Anton Korobeynikov 2810a0ab80 Windows TLS: Section name prefix to ensure correct order 
The linker sorts the .tls$<xyz> sections by name, and we need
to make sure any extra sections we produce (e.g. for weak globals) 
always end up between .tls$AAA and .tls$ZZZ, even if the name 
starts with e.g. an underscore.
