Dimitry Andric	0f0f2bfa77	Pull in r227752 from upstream llvm trunk (by Michael Kuperstein): ... [X86] Convert esp-relative movs of function arguments to pushes, step 2 This moves the transformation introduced in r223757 into a separate MI pass. This allows it to cover many more cases (not only cases where there must be a reserved call frame), and perform rudimentary call folding. It still doesn't have a heuristic, so it is enabled only for optsize/minsize, with stack alignment <= 8, where it ought to be a fairly clear win. (Re-commit of r227728) Differential Revision: http://reviews.llvm.org/D6789 This helps to get sys/boot/i386/boot2 below the required size again, when optimizing with -Oz.	2015-02-02 20:34:40 +00:00
