| | | | llvm-svn: 1375
* The old getIndices has been deprecated, because it no longer works. It nowChris Lattner2001-11-261-2/+2

| | | | | | a star after it - only for debugging llvm-svn: 1309

| | | | llvm-svn: 1308

| | | | llvm-svn: 1306

| | | | llvm-svn: 1305

| | | | llvm-svn: 1303

| | | | llvm-svn: 1300
* Remove much cruft from the MemAccessInst instructionChris Lattner2001-11-142-3/+3
| | | | llvm-svn: 1298
* commented out lines printing code after schedulingRuchira Sasanka2001-11-131-2/+2
| | | | llvm-svn: 1295
* Fixed a bug concering LR spilling. Earlier, added spilled code was not insertedRuchira Sasanka2001-11-131-27/+43
| | | | | | into the instruction stream correctly. llvm-svn: 1294
* Do the same for allocating spills to get their alignment right too.Vikram S. Adve2001-11-121-1/+2
| | | | llvm-svn: 1285
* When allocating space on stack for writing a register,Vikram S. Adve2001-11-121-1/+3
| | | | | | | use the size of the register, not the size of the Value type, to get the right alignment. llvm-svn: 1284
* Bug fix in offset alignment computations: don't subtract the paddingVikram S. Adve2001-11-121-37/+32
| | | | | | value from size *before* subtracting size from offset! llvm-svn: 1283
* For phi elimination, now we are generating only one instructionRuchira Sasanka2001-11-121-15/+5
| | | | | | | using cpValue2Value instead of passing vector to createCopyInstructionByType. llvm-svn: 1272
* Eliminate most uses of the machine instruction vector for each LLVM instr,Vikram S. Adve2001-11-122-63/+75
| | | | | | | | since some m. instr. may be generated by LLVM instrs. in other blocks. Handle non-SSA (anti and output) edges and true edges uniformly by working with machine instructions alone. llvm-svn: 1269
* Added phi elimination code - not finalRuchira Sasanka2001-11-121-0/+100
| | | | llvm-svn: 1264

| | | | llvm-svn: 1263

| | | | | | LLVM instruction is no longer recorded in each node, but BB is. llvm-svn: 1262
* Adjust all stack variable offsets to be aligned by size.Vikram S. Adve2001-11-121-13/+55
| | | | llvm-svn: 1261
* Fix errors in computing downgrowing offsets, and inVikram S. Adve2001-11-111-11/+14

* Only add true dep. edges from an earlier to a later instruction.Vikram S. Adve2001-11-112-31/+40
| | | | | | | This wasn't a problem until we started putting copies for Phi values that produced cycles in the SchedGraph! llvm-svn: 1254
* Changed code to ignore Phi Nodes in PhyRegAllocRuchira Sasanka2001-11-102-1/+8
| | | | llvm-svn: 1253
* Coalesing bug fix - now checks for the same regType instead of the sameRuchira Sasanka2001-11-101-3/+6
| | | | | | regClass since FP class has two reg Types. llvm-svn: 1236
* No major changeRuchira Sasanka2001-11-091-3/+3
| | | | llvm-svn: 1235
* Use node->getOpCode() instead of node->getMachineInstr()->getOpCode().Vikram S. Adve2001-11-091-36/+38
| | | | | | Much nicer. llvm-svn: 1223
* Add method declChris Lattner2001-11-081-0/+4
| | | | llvm-svn: 1217
* corrected insertCode4Spilled ... bug.Ruchira Sasanka2001-11-081-8/+17
| | | | llvm-svn: 1212
* Uncommented LR spill code insertionRuchira Sasanka2001-11-081-2/+85
| | | | llvm-svn: 1207
* Major change to how defs are found when adding dependences (theyVikram S. Adve2001-11-082-171/+69
| | | | | | | | are now found as part of the initial walk of the machine code). Also memory load/store instructions can be generated for non-memory LLVM instructions, which wasn't handled before. It is now. llvm-svn: 1199
* MachineCodeForMethod is now an annotation on class Method.Vikram S. Adve2001-11-081-1/+1
| | | | llvm-svn: 1198
* Added two minor methods.Vikram S. Adve2001-11-082-3/+8
| | | | llvm-svn: 1187
* Removed class RegStackOffsets and used class MachineCodeForMethodVikram S. Adve2001-11-082-293/+38
| | | | | | directly to manage stack frame. llvm-svn: 1186
* Major overhaul of stack frame management.Vikram S. Adve2001-11-084-23/+162
