* Allow i/s to match (gv+c). This fixes ↵Chris Lattner2007-05-031-10/+31
| | | | | | | | CodeGen/PowerPC/2007-05-03-InlineAsm-S-Constraint.ll and PR1382 llvm-svn: 36672

* Properly set arguments bitwidth of EHSELECT nodeAnton Korobeynikov2007-05-021-2/+2
| | | | llvm-svn: 36654
* Use 'static const char' instead of 'static const int'.Devang Patel2007-05-0218-31/+31
| | | | | | | Due to darwin gcc bug, one version of darwin linker coalesces static const int, which defauts PassID based pass identification. llvm-svn: 36652
* Fix build error.Lauro Ramos Venancio2007-05-022-2/+2
| | | | llvm-svn: 36648
* Fix couple of bugs connected with eh info:Anton Korobeynikov2007-05-011-15/+27
| | | | | | | 1. Correct output offsets on Linux 2. Fix "style" of personality function. It shouldn't be indirect. llvm-svn: 36633

| | | | | | eliminateFrameIndex() must adjust SP offset with size of call frames. llvm-svn: 36625
* Forgot about chain result; also UNDEF cannot have multiple values.Evan Cheng2007-05-011-12/+12

* llvm bug #1350, parts 1, 2, and 3.Nate Begeman2007-05-011-2/+2
| | | | llvm-svn: 36618
* Under normal circumstances, when a frame pointer is not required, we reserveEvan Cheng2007-05-011-17/+14
| | | | | | | | | | | | argument space for call sites in the function immediately on entry to the current function. This eliminates the need for add/sub sp brackets around call sites. However, this is not always a good idea. If the "call frame" is large and the target load / store instructions have small immediate field to encode sp offset, this can cause poor codegen. In the worst case, this can make it impossible to scavenge a register if the reserved spill slot is pushed too far apart from sp / fp. llvm-svn: 36607
* * Only turn a load to UNDEF if all of its outputs have no uses (indexed loadsEvan Cheng2007-05-011-5/+20

| | | | | | | | register, preallocate all input registers and the early clobbered output. This fixes PR1357 and CodeGen/PowerPC/2007-04-30-InlineAsmEarlyClobber.ll llvm-svn: 36599

* memory operands that have a direct operand should have their stores createdChris Lattner2007-04-281-35/+42
| | | | | | | | | | | | | before the copies into physregs are done. This avoids having flag operands skip the store, causing cycles in the dag at sched time. This fixes infinite loops on these tests: test/CodeGen/Generic/2007-04-08-MultipleFrameIndices.ll for PR1308 test/CodeGen/PowerPC/2007-01-29-lbrx-asm.ll test/CodeGen/PowerPC/2007-01-31-InlineAsmAddrMode.ll test/CodeGen/X86/2006-07-12-InlineAsmQConstraint.ll for PR828 llvm-svn: 36547

| | | | | | | | | If the operand is not already an indirect operand, spill it to a constant pool entry or a stack slot. This fixes PR1356 and CodeGen/X86/2007-04-27-InlineAsm-IntMemInput.ll llvm-svn: 36536

| | | | | | | | | - A register def / use now implicitly affects sub-register liveness but does not affect liveness information of super-registers. - Def of a larger register (if followed by a use later) is treated as read/mod/write of a smaller register. llvm-svn: 36434
