* Place the GEP instructions nearer to the instructions which use them.Bill Wendling2012-01-271-37/+36
| | | | | | | | | | | | GEP instructions are there for the compiler and shouldn't really output much code (if any at all). When a GEP is stored in the entry block, Fast ISel (for one) will not know that it could fold it into further uses. For instance, inside of the EH handling code. This results in a lot of unnecessary spills and loads which bloat code and slows down pretty much everything. <rdar://problem/10694814> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149114 91177308-0d34-0410-b5e6-96231b3b80d8

* Handle call-clobbered ymm registers on Win64.Jakob Stoklund Olesen2012-01-262-1/+8
| | | | | | | | | | | | | | The Win64 calling convention has xmm6-15 as callee-saved while still clobbering all ymm registers. Add a YMM_HI_6_15 pseudo-register that aliases the clobbered part of the ymm registers, and mark that as call-clobbered. This allows live xmm registers across calls. This hack wouldn't be necessary with RegisterMask operands representing the call clobbers, but they are not quite operational yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149088 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix for the following bug in AVX codegen for double-to-int conversions:Victor Umansky2012-01-261-2/+2
| | | | | | | | | | | | | | | . "fptosi" and "fptoui" IR instructions are defined with round-to-zero rounding mode. . Currently for AVX mode for <4xdouble> and <8xdouble> the "VCVTPD2DQ.128" and "VCVTPD2DQ.256" instructions are selected (for .fp_to_sint. DAG node operation ) by AVX codegen. However they use round-to-nearest-even rounding mode. . Consequently, the conversion produces incorrect numbers. The fix is to replace selection of VCVTPD2DQ instructions with VCVTTPD2DQ instructions. The latter use truncate (i.e. round-to-zero) rounding mode. As .fp_to_sint. DAG node operation is used only for lowering of "fptosi" and "fptoui" IR instructions, the fix in X86InstrSSE.td definition file doesn.t have an impact on other LLVM flows. The patch includes changes in the .td file, LIT test for the changes and a fix in a legacy LIT test (which produced asm code conflicting with LLVN IR spec). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149056 91177308-0d34-0410-b5e6-96231b3b80d8
