Stefan Pintilie	2812c15156	[PowerPC] Fix missing nop after call to weak callee. ... Weak functions can be replaced by other functions at link time. Previously it was assumed that no matter what the weak callee function was replaced with it would still share the same TOC as the caller. This is no longer true as a weak callee with a TOC setup can be replaced by another function that was compiled with PC Relative and does not have a TOC at all. This patch makes sure that all calls to functions defined as weak from a caller that has a valid TOC have a nop after the call to allow a place for the linker to restore the TOC.

Nemanja Ivanovic	d864d93496	[PowerPC] Handle constant zero bits in BitPermutationSelector ... We currently crash when analyzing an AssertZExt node that has some bits that are constant zeros (i.e. as a result of an and with a constant). This issue was reported in https://bugs.llvm.org/show_bug.cgi?id=41088 and this patch fixes that. Differential revision: https://reviews.llvm.org/D72038	2020-01-10 09:55:34 -06:00
