| | | | | | dead loads. llvm-svn: 56529
* Add a method to MachineInstr for testing whether it makesDan Gohman2008-09-241-9/+30

* Properly handle 'm' inline asm constraints. If a GV is being selected for ↵Evan Cheng2008-09-249-23/+61
| | | | | | the addressing mode, it requires the same logic for PIC relative addressing, etc. llvm-svn: 56526
* Move FN_NOTE_AlwaysInline and other out of ParamAttrs namespace.Devang Patel2008-09-2311-34/+34
| | | | | | Do not check isDeclaration() in hasNote(). It is clients' responsibility. llvm-svn: 56524

* Use parameter attribute store (soon to be renamed) forDevang Patel2008-09-2316-42/+52
| | | | | | Function Notes also. Function notes are stored at index ~0. llvm-svn: 56511
* Now that DeadMachineInstructionElim is basically workingDan Gohman2008-09-231-6/+0
| | | | | | | correctly, it's not necessary to explicitly remove registers from their use-def lists. llvm-svn: 56509
* Arrange for FastISel code to have access to the MachineModuleInfoDan Gohman2008-09-235-8/+18
| | | | | | object. This will be needed to support debug info. llvm-svn: 56508
* Track local physical register liveness. This is not the mostDan Gohman2008-09-231-3/+53
| | | | | | | efficient implementation possible, but it's pretty simple and good enough for the time being. llvm-svn: 56504

| | | | llvm-svn: 56501
* Replace the LiveRegs SmallSet with a simple counter that keepsDan Gohman2008-09-232-23/+29
| | | | | | | track of the number of live registers, which is all the set was being used for. llvm-svn: 56498
* Fix these enums' starting values to reflect the way thatDan Gohman2008-09-239-9/+9
| | | | | | instruction opcodes are now numbered. No functionality change. llvm-svn: 56497
* Delete an unused function.Dan Gohman2008-09-231-10/+0

* Move the code for initializing the global base reg out ofDan Gohman2008-09-233-29/+43
| | | | | | | X86ISelDAGToDAG.cpp and into X86InstrInfo.cpp. This will allow it to be reused by FastISel. llvm-svn: 56494

* Support x86 specific inline asm modifier 'J'.Evan Cheng2008-09-221-0/+8
| | | | llvm-svn: 56483
* Fix the alignment of loads from constant pool entries when theDan Gohman2008-09-222-1/+7
| | | | | | | load address has an offset from the base of the constant pool entry. llvm-svn: 56479
* Add hasNote() to check note associated with a function.Devang Patel2008-09-228-22/+31

* Instead of setPreservesAll, just mark them preseving machine loop info and ↵Evan Cheng2008-09-227-7/+14
| | | | | | machine dominators. llvm-svn: 56475
* Significant improvements to the logic for merging live intervals. This code ↵Owen Anderson2008-09-221-15/+53
| | | | | | | | | can't just use LI::MergeValueAsValue, as its behavior in the presence of overlapping ranges isn't what StrongPHIElimination wants. llvm-svn: 56472
* Make log, log2, log10, exp, exp2 use Expand byDale Johannesen2008-09-228-71/+12

| | | | | | | (srl x, (trunc (and y, c))) -> (srl x, (and (trunc y), c)) etc. when both "trunc" and "and" have single uses. llvm-svn: 56452
* Change the calling convention used when tail call optimization is enabled ↵Arnold Schwaighofer2008-09-223-22/+2
| | | | | | from CC_X86_32_TailCall to CC_X86_32_FastCC. llvm-svn: 56436

* Fold immediates into X86 shifts with fast isel. This generates:Chris Lattner2008-09-211-15/+24
| | | | | | | | | | | | | sarl $3, %ecx instead of: movl $3, %ecx sarl %cl, %edx This shrinks fast isel 176.gcc by about 2000 instructions (.3%) llvm-svn: 56413
* Factor out code into HandleVirtRegDef, for consistency withDan Gohman2008-09-211-13/+12
| | | | | | | Handle{Virt,Phys}Reg{Def,Use}. Remove a redundant check for register zero, and redundant checks for isPhysicalRegister. llvm-svn: 56412
* Instead of building a list and sorting it just to find a maximum element,Dan Gohman2008-09-211-26/+9
| | | | | | compute the maximum element directly. llvm-svn: 56411
* Fetch the starting index of the block when assigning intervals. This gets ↵Owen Anderson2008-09-211-2/+2
| | | | | | | | live-in indices correct in the presence of things like EH labels. llvm-svn: 56410

* Implement review feedback from Devang: make useDuncan Sands2008-09-201-26/+11

* Teach coalescer about earlyclobber bits.Dale Johannesen2008-09-202-2/+17

* Fix PR2808. When regalloc runs out of register, it spill a physical register ↵Evan Cheng2008-09-201-1/+4
| | | | | | around the live interval being allocated. Do not continue to try to spill another register, just grab the physical register and move on. llvm-svn: 56381
