* Remove unused AsmPrinter OptLevel argument, and propogate.Daniel Dunbar2009-07-011-1/+0
| | | | | | | - This more or less amounts to a revert of r65379. I'm curious to know what happened that caused this variable to become unused. llvm-svn: 74579
* Split thumb-related stuff into separate classes.Anton Korobeynikov2009-06-261-9/+9
| | | | | | Step 1: ARMInstructionInfo => {ARM,Thumb}InstructionInfo llvm-svn: 74329
* Add a ARM specific pre-allocation pass that re-schedule loads / stores fromEvan Cheng2009-06-131-5/+5
| | | | | | | | | | | consecutive addresses togther. This makes it easier for the post-allocation pass to form ldm / stm. This is step 1. We are still missing a lot of ldm / stm opportunities because of register allocation are not done in the desired order. More enhancements coming. llvm-svn: 73291
* Fix new CodeEmitter stuff to follow LLVM codying style. Patch by Aaron GrayBruno Cardoso Lopes2009-06-011-9/+4

* First patch in the direction of splitting MachineCodeEmitter in two subclasses:Bruno Cardoso Lopes2009-05-301-0/+12
| | | | | | JITCodeEmitter and ObjectCodeEmitter. No functional changes yet. Patch by Aaron Gray llvm-svn: 72631
* Instead of passing in an unsigned value for the optimization level, use an enum,Bill Wendling2009-04-291-1/+3
| | | | | | | which better identifies what the optimization is doing. And is more flexible for future uses. llvm-svn: 70440
* Second attempt:Bill Wendling2009-04-291-1/+1
| | | | | | | | | | | | Massive check in. This changes the "-fast" flag to "-O#" in llc. If you want to use the old behavior, the flag is -O0. This change allows for finer-grained control over which optimizations are run at different -O levels. Most of this work was pretty mechanical. The majority of the fixes came from verifying that a "fast" variable wasn't used anymore. The JIT still uses a "Fast" flag. I'll change the JIT with a follow-up patch. llvm-svn: 70343
* r70270 isn't ready yet. Back this out. Sorry for the noise.Bill Wendling2009-04-281-1/+1

* CodeGen still defaults to non-verbose asm, but llc now overrides it and ↵Evan Cheng2009-03-251-1/+1

* Overhaul my earlier submission due to feedback. It's a large patch, but most ofBill Wendling2009-02-241-1/+3
| | | | | | | | | | | | them are generic changes. - Use the "fast" flag that's already being passed into the asm printers instead of shoving it into the DwarfWriter. - Instead of calling "MI->getParent()->getParent()" for every MI, set the machine function when calling "runOnMachineFunction" in the asm printers. llvm-svn: 65379
* Tidy up #includes, deleting a bunch of unnecessary #includes.Dan Gohman2009-01-051-1/+0
