*	[PowerPC] Remove UseVSXReg	Stefan Pintilie	2019-03-26	1	-16/+16
\| \| \| \| \| \| \| \| \| \|	The UseVSXReg flag can be safely removed and the code cleaned up. Patch By: Yi-Hong Liu Differential Revision: https://reviews.llvm.org/D58685 llvm-svn: 357028
*	[PowerPC] Reduce register pressure by not materializing a constant just for ↵	Lei Huang	2017-07-10	1	-8/+8
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	use as an index register for X-Form loads/stores. For this example: float test (int *arr) { return arr[2]; } We currently generate the following code: li r4, 8 lxsiwax f0, r3, r4 xscvsxdsp f1, f0 With this patch, we will now generate: addi r3, r3, 8 lxsiwax f0, 0, r3 xscvsxdsp f1, f0 Originally reported in: https://bugs.llvm.org/show_bug.cgi?id=27204 Differential Revision: https://reviews.llvm.org/D35027 llvm-svn: 307553
*	[PowerPC] Improvements for BUILD_VECTOR Vol. 4	Nemanja Ivanovic	2016-12-06	1	-16/+16
\| \| \| \| \| \| \| \| \| \| \| \|	This is the final patch in the series of patches that improves BUILD_VECTOR handling on PowerPC. This adds a few peephole optimizations to remove redundant instructions. It also adds a large test case which encompasses a large set of code patterns that build vectors - this test case was the motivator for this series of patches.

*	[Power9] Part-word VSX integer scalar loads/stores and sign extend instructions	Nemanja Ivanovic	2016-10-04	1	-0/+1132
	This patch corresponds to review: https://reviews.llvm.org/D23155 This patch removes the VSHRC register class (based on D20310) and adds exploitation of the Power9 sub-word integer loads into VSX registers as well as vector sign extensions. The new instructions are useful for a few purposes: Int to Fp conversions of 1 or 2-byte values loaded from memory Building vectors of 1 or 2-byte integers with values loaded from memory Storing individual 1 or 2-byte elements from integer vectors This patch implements all of those uses. llvm-svn: 283190
