* Introduce 'UseSSEx' to force SSE legacy encodingMichael Liao2012-08-301-22/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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

* Instruction scheduling itinerary for Intel Atom.Andrew Trick2012-02-011-128/+144
| | | | | | | | | | | | | | Adds an instruction itinerary to all x86 instructions, giving each a default latency of 1, using the InstrItinClass IIC_DEFAULT. Sets specific latencies for Atom for the instructions in files X86InstrCMovSetCC.td, X86InstrArithmetic.td, X86InstrControl.td, and X86InstrShiftRotate.td. The Atom latencies for the remainder of the x86 instructions will be set in subsequent patches. Adds a test to verify that the scheduler is working. Also changes the scheduling preference to "Hybrid" for i386 Atom, while leaving x86_64 as ILP.

* Many of the SSE patterns should not be selected when AVX is available. This ↵Evan Cheng2011-12-081-0/+4
| | | | | | | | | | | | | | | | | | | led to the following code in X86Subtarget.cpp if (HasAVX) X86SSELevel = NoMMXSSE; This is so patterns that are predicated on hasSSE3, etc. would not be selected when avx is available. Instead, the AVX variant is selected. However, this breaks instructions which do not have AVX variants. The right way to fix this is for the SSE but not-AVX patterns to predicate on something like hasSSE3() && !hasAVX(). Then we can take out the hack in X86Subtarget.cpp. Patterns which do not have AVX variants do not need to change. However, we need to audit all the patterns before we make the change. This patch is workaround that fixes one specific case, the prefetch instructions. rdar://10538297 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146163 91177308-0d34-0410-b5e6-96231b3b80d8
