* [X86] Enable call frame optimization ("mov to push") not only for optsize ↵Hans Wennborg2016-03-301-1/+1
| | | | | | | | | | (PR26325) The size savings are significant, and from what I can tell, both ICC and GCC do this. Differential Revision: http://reviews.llvm.org/D18573 llvm-svn: 264966

| | | | | | scalar arguments in registers. This patch defines a new fastcc CC which is slightly different from the FastCall CC. In addition to passing integer arguments in ECX and EDX, it also specify doubles are passed in 8-byte slots which are 8-byte aligned (instead of 4-byte aligned). This avoids a potential performance hazard where doubles span cacheline boundaries. llvm-svn: 55807
