2013-03-14Teach X86 MC instruction lowering that VMOVAPSrr and other VEX-encoded ↵Craig Topper
register to register moves should be switched from using the MRMSrcReg form to the MRMDestReg form if the source register is a 64-bit extended register and the destination register is not. This allows the instruction to be encoded using the 2-byte VEX form instead of the 3-byte VEX form. The GNU assembler has similar behavior. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177011 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-12ARM cost model: Increase the cost for vector casts that use the stackArnold Schwaighofer
Increase the cost of v8/v16-i8 to v8/v16-i32 casts and truncates as the backend currently lowers those using stack accesses. This was responsible for a significant degradation on MultiSource/Benchmarks/Trimaran/enc-pc1/enc-pc1 where we vectorize one loop to a vector factor of 16. After this patch we select a vector factor of 4 which will generate reasonable code. unsigned char cle[32]; void test(short c) { unsigned short compte; for (compte = 0; compte <= 31; compte++) { cle[compte] = cle[compte] ^ c; } } radar://13220512 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176898 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-12Don't reserve R2 on Darwin/PPCHal Finkel
Now that only the register-scavenger version of the CR spilling code remains, we no longer need the Darwin R2 hack. Darwin can use R0 as a spare register in any case where the System V ABI uses it (R0 is special architecturally, and so is reserved under all common ABIs). A few test cases needed to be updated to reflect the register-allocation changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176868 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-08R600/SI: Use source schedulerMichel Danzer
This is certainly not the last word on scheduling for this target, but right now this allows a few apps to run / finish with radeonsi, most notably UT2004 / Lightsmark. They fail to compile some shaders with the default scheduler because it ends up trying to spill registers, which we don't support yet (and which is probably a bad idea in general for performance if it can be avoided).
