| * | manually upgrade a bunch of tests to modern syntax, and remove some that | Chris Lattner | 2011-06-17 | 1 | -1/+1 |
| | | | | | | | are either unreduced or only test old syntax. llvm-svn: 133228 | ||||
| * | Implement mulo x, 2 -> addo x, x in DAGCombiner. | Benjamin Kramer | 2011-05-21 | 1 | -0/+24 |

| * | As Dan pointed out, movzbl, movsbl, and friends are nicer than their alias | Bill Wendling | 2011-04-14 | 1 | -1/+1 |
| | | | | | | | (movzx/movsx) because they give more information. Revert that part of the patch. llvm-svn: 129498 | ||||
| * | Have the X86 back-end emit the alias instead of what's being aliased. In most | Bill Wendling | 2011-04-14 | 1 | -1/+1 |
| | | | | | | | cases, it's much nicer and more informative reading the alias. llvm-svn: 129497 | ||||
| * | it turns out that when ".with.overflow" intrinsics were added to the X86 | Chris Lattner | 2010-12-05 | 1 | -1/+7 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | backend that they were all implemented except umul. This one fell back to the default implementation that did a hi/lo multiply and compared the top. Fix this to check the overflow flag that the 'mul' instruction sets, so we can avoid an explicit test. Now we compile: void *func(long count) { return new int[count]; } into: __Z4funcl: ## @_Z4funcl movl $4, %ecx ## encoding: [0xb9,0x04,0x00,0x00,0x00] movq %rdi, %rax ## encoding: [0x48,0x89,0xf8] mulq %rcx ## encoding: [0x48,0xf7,0xe1] seto %cl ## encoding: [0x0f,0x90,0xc1] testb %cl, %cl ## encoding: [0x84,0xc9] movq $-1, %rdi ## encoding: [0x48,0xc7,0xc7,0xff,0xff,0xff,0xff] cmoveq %rax, %rdi ## encoding: [0x48,0x0f,0x44,0xf8] jmp __Znam ## TAILCALL instead of: __Z4funcl: ## @_Z4funcl movl $4, %ecx ## encoding: [0xb9,0x04,0x00,0x00,0x00] movq %rdi, %rax ## encoding: [0x48,0x89,0xf8] mulq %rcx ## encoding: [0x48,0xf7,0xe1] testq %rdx, %rdx ## encoding: [0x48,0x85,0xd2] movq $-1, %rdi ## encoding: [0x48,0xc7,0xc7,0xff,0xff,0xff,0xff] cmoveq %rax, %rdi ## encoding: [0x48,0x0f,0x44,0xf8] jmp __Znam ## TAILCALL Other than the silly seto+test, this is using the o bit directly, so it's going in the right direction. llvm-svn: 120935 | ||||
| * | Eliminate more uses of llvm-as and llvm-dis. | Dan Gohman | 2009-09-08 | 1 | -1/+1 |

| * | Add some generic expansion logic for SMULO and UMULO. Fixes UMULO | Eli Friedman | 2009-06-16 | 1 | -0/+8 |
| support for x86, and UMULO/SMULO for many architectures, including PPC (PR4201), ARM, and Cell. The resulting expansion isn't perfect, but it's not bad. llvm-svn: 73477 | |||||
