Dan Gohman	5f6f8101d5	Split the Add, Sub, and Mul instruction opcodes into separate ... integer and floating-point opcodes, introducing FAdd, FSub, and FMul. For now, the AsmParser, BitcodeReader, and IRBuilder all preserve backwards compatability, and the Core LLVM APIs preserve backwards compatibility for IR producers. Most front-ends won't need to change immediately. This implements the first step of the plan outlined here: http://nondot.org/sabre/LLVMNotes/IntegerOverflow.txt llvm-svn: 72897	2009-06-04 22:49:04 +00:00
Chris Lattner	682346a7b0	Infer alignment of loads and increase their alignment when we can tell they are ... from the stack. This allows us to compile stack-align.ll to: _test: movsd LCPI1_0, %xmm0 movapd %xmm0, %xmm1 *** andpd 4(%esp), %xmm1 andpd _G, %xmm0 addsd %xmm1, %xmm0 movl 20(%esp), %eax movsd %xmm0, (%eax) ret instead of: _test: movsd LCPI1_0, %xmm0 ** movsd 4(%esp), %xmm1 ** andpd %xmm0, %xmm1 andpd _G, %xmm0 addsd %xmm1, %xmm0 movl 20(%esp), %eax movsd %xmm0, (%eax) ret llvm-svn: 46401	2008-01-26 19:45:50 +00:00
