* Added saveBBreferences() for BasicBlock resolution.Misha Brukman2003-05-301-4/+8
| | | | llvm-svn: 6451
* so far everything compilesGuochun Shi2003-05-302-23/+39
| | | | llvm-svn: 6423
* Correctly write out binary data as chars, before they're cast to ints.Misha Brukman2003-05-281-2/+1
| | | | llvm-svn: 6385
* Added a debugging code emitter that prints code to a file, debug to std::cerr,Misha Brukman2003-05-271-0/+121
| | | | | | | and passes the real code to a memory-outputting code emitter. This may be removed at a later point in development. llvm-svn: 6379
* (1) Added special register class containing (for now) %fsr.Vikram S. Adve2003-05-279-51/+54
| | | | | | | | | | | | | Fixed spilling of %fcc[0-3] which are part of %fsr. (2) Moved some machine-independent reg-class code to class TargetRegInfo from SparcReg{Class,}Info. (3) Renamed MachienOperand::opIsDef to MachineOperand::opIsDefOnly() and related functions and flags. Fixed several bugs where only "isDef" was being checked, not "isDefAndUse". llvm-svn: 6341
* Cleaned up code layout. No functional changes.Misha Brukman2003-05-222-678/+622
| | | | llvm-svn: 6304
* Kill `using' directives.Misha Brukman2003-05-222-51/+47
| | | | llvm-svn: 6301
* Use a kill, not a dead definition, update commentChris Lattner2003-05-121-5/+4
| | | | llvm-svn: 6131
* * Keep LiveVariable information more up-to-date and consistentChris Lattner2003-05-121-7/+87
| | | | | | | | | * *** Finally mark values that are inputs to PHIs as killed when appropriate. This should make the generated code quite a bit better. For example, the local-ra will not have to spill PHI inputs at the end of predecessor BB's anymore. llvm-svn: 6117
* Fix bug where we could iterate off the end of a basic blockChris Lattner2003-05-121-2/+3
| | | | llvm-svn: 6116
* * Keep the BBMap around as long as the pass is liveChris Lattner2003-05-121-8/+23
| | | | | | | * Change getVarInfo to take real virtual register numbers and offset them itself. This has caused me so much grief, it's not even funny. llvm-svn: 6115
* Fix N^2 algorithmChris Lattner2003-05-121-25/+34

* Re-add gross hack, it's still necessary. :(Chris Lattner2003-05-061-2/+12

* Remove hideously nasty hackChris Lattner2003-05-061-12/+2
| | | | llvm-svn: 6011
* Debug output should go to cerr, not cout, because that's where bytecode goes.Misha Brukman2003-05-041-2/+2

* Just some code beautification changes I had sitting around in my tree.Misha Brukman2003-04-222-22/+15

* Fixed compilation errors, command-line argument declarations, cleaned up code toMisha Brukman2003-04-104-267/+257
| | | | | | | | | | | | look nicer and removed useless stuff. Also renamed a few variables, moved them into namespaces, converted outputting to a file into a print to std::cerr with a DEBUG() guard, as all passes should do anyway. No functional changes have been made. However, this code now compiles. llvm-svn: 5769
* Made the code readable:Misha Brukman2003-04-094-1884/+1977
| | | | | | | | | * Lines must be wrapped at 80 chars. This is a hard limit. * Consistent style on functions, braces, if, for, etc. Code must be readable. No functional changes have been made, even though I added a new typedef. llvm-svn: 5768
* change the include file names and some class names to make it compileGuochun Shi2003-04-064-24/+30
