Sanjay Patel 2e19fa34bb Shrinkify libcalls: use float versions of double libm functions with fast-math (bug 17850) ... When a call to a double-precision libm function has fast-math semantics (via function attribute for now because there is no IR-level FMF on calls), we can avoid fpext/fptrunc operations and use the float version of the call if the input and output are both float. We already do this optimization using a command-line option; this patch just adds the ability for fast-math to use the existing functionality. I moved the cl::opt from InstructionCombining into SimplifyLibCalls because it's only ever used internally to that class. Modified the existing test cases to use the unsafe-fp-math attribute rather than repeating all tests. This patch should solve: http://llvm.org/bugs/show_bug.cgi?id=17850 Differential Revision: http://reviews.llvm.org/D5893 llvm-svn: 220390		2014-10-22 15:29:23 +00:00
