* Introduce 'UseSSEx' to force SSE legacy encodingMichael Liao2012-08-301-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Add 'UseSSEx' to force SSE legacy insn not being selected when AVX is enabled. As the penalty of inter-mixing SSE and AVX instructions, we need prevent SSE legacy insn from being generated except explicitly specified through some intrinsics. For patterns supported by both SSE and AVX, so far, we force AVX insn will be tried first relying on AddedComplexity or position in td file. It's error-prone and introduces bugs accidentally. 'UseSSEx' is disabled when AVX is turned on. For SSE insns inherited by AVX, we need this predicate to force VEX encoding or SSE legacy encoding only. For insns not inherited by AVX, we still use the previous predicates, i.e. 'HasSSEx'. So far, these insns fall into the following categories: * SSE insns with MMX operands * SSE insns with GPR/MEM operands only (xFENCE, PREFETCH, CLFLUSH, CRC, and etc.) * SSE4A insns. * MMX insns. * x87 insns added by SSE. 2 test cases are modified: - test/CodeGen/X86/fast-isel-x86-64.ll AVX code generation is different from SSE one. 'vcvtsi2sdq' cannot be selected by fast-isel due to complicated pattern and fast-isel fallback to materialize it from constant pool. - test/CodeGen/X86/widen_load-1.ll AVX code generation is different from SSE one after fixing SSE/AVX inter-mixing. Exec-domain fixing prefers 'vmovapd' instead of 'vmovaps'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162919 91177308-0d34-0410-b5e6-96231b3b80d8
* Revert r145273 and fix in SelectionDAG::InferPtrAlignment() instead.Evan Cheng2011-11-281-1/+1
| | | | | | | | | | | | Conservatively returns zero when the GV does not specify an alignment nor is it initialized. Previously it returns ABI alignment for type of the GV. However, if the type is a "packed" type, then the under-specified alignments is attached to the load / store instructions. In that case, the alignment of the type cannot be trusted. rdar://10464621 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145300 91177308-0d34-0410-b5e6-96231b3b80d8

Also (while I was at it) cleaned up the X86 tables, removing tabs and 80-line violations.
