*	[SystemZ] Wait with selection of legal vector/FP constants until Select().	Jonas Paulsson	2019-02-26	1	-8/+32
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This patch aims to make sure that any such constant that can be generated with a vector instruction (for example VGBM) is recognized as such during legalization and kept as a target independent node through post-legalize DAGCombining. Two new functions named isVectorConstantLegal() and loadVectorConstant() replace old ways of handling vector/FP constants. A new struct named SystemZVectorConstantInfo is used to cache the results of isVectorConstantLegal() and pass them onto loadVectorConstant(). Support for fp128 constants in the presence of FeatureVectorEnhancements1 (z14) has been added. Review: Ulrich Weigand https://reviews.llvm.org/D58270 llvm-svn: 354896
*	[SystemZ] Wait with VGBM selection until after DAGCombine2.	Jonas Paulsson	2019-02-06	1	-32/+8
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Don't lower BUILD_VECTORs to BYTE_MASK, but instead expose the BUILD_VECTORs to the DAGCombiner and select them to VGBM in Select(). This allows the DAGCombiner to understand the constant vector values. For floating point, only all-zeros vectors are now generated with VGBM, as it turned out to be somewhat complicated to handle any arbitrary constants, while in practice this is very rare and hardly needed. The SystemZ ISD opcodes z_byte_mask, z_vzero and z_vones have been removed. Review: Ulrich Weigand https://reviews.llvm.org/D57152 llvm-svn: 353325
*	[SystemZ] Add CodeGen support for v2f64	Ulrich Weigand	2015-05-05	1	-0/+43
	This adds ABI and CodeGen support for the v2f64 type, which is natively supported by z13 instructions. Based on a patch by Richard Sandiford. llvm-svn: 236522
