| | | | llvm-svn: 150091
* TargetPassConfig: confine the MC configuration to TargetMachine.Andrew Trick2012-02-041-74/+16
| | | | | | | | | | Passes prior to instructon selection are now split into separate configurable stages. Header dependencies are simplified. The bulk of this diff is simply removal of the silly DisableVerify flags. Sorry for the target header churn. Attempting to stabilize them. llvm-svn: 149754
* Move TargetPassConfig implementation into Passes.cppAndrew Trick2012-02-041-1/+310
| | | | llvm-svn: 149753
* Make TargetPassConfig an ImmutablePass so CodeGenPasses can query optionsAndrew Trick2012-02-041-0/+34

* Delete the linear scan register allocator.Jakob Stoklund Olesen2011-11-121-5/+0
| | | | | | | | | RegAllocGreedy has been the default for six months now. Deleting RegAllocLinearScan makes it possible to also delete VirtRegRewriter and clean up the spiller code. llvm-svn: 144475
* Update comment.Jakob Stoklund Olesen2011-04-301-2/+2
| | | | llvm-svn: 130582
* Use a greedy algorithm for allocating registers.Jakob Stoklund Olesen2011-04-301-3/+3
| | | | llvm-svn: 130568
* Force the greedy register allocator to be linked alongside linear scan.Jakob Stoklund Olesen2011-04-191-0/+5
| | | | | | This means that the new register allocator can be used with 'clang -mllvm -regalloc=greedy'. llvm-svn: 129764
* Use the fast register allocator by default for -O0 builds.Jakob Stoklund Olesen2010-06-031-1/+1
| | | | | | This affects both llvm-gcc and clang. llvm-svn: 105372
* Add a -regalloc=default option that chooses a register allocator based on the -OJakob Stoklund Olesen2010-05-271-6/+20
| | | | | | | | | optimization level. This only really affects llc for now because both the llvm-gcc and clang front ends override the default register allocator. I intend to remove that code later. llvm-svn: 104904
* Uniformize the way these options are printed. Requested byDuncan Sands2010-02-181-1/+1
| | | | | | Russell Wallace. llvm-svn: 96580
* Clean up the use of static and anonymous namespaces. This turned upDan Gohman2008-05-131-8/+5
| | | | | | | several things that were neither in an anonymous namespace nor static but not intended to be global. llvm-svn: 51017
* Make several variable declarations static.Dan Gohman2008-05-061-0/+1
| | | | llvm-svn: 50696
* Remove attribution from file headers, per discussion on llvmdev.Chris Lattner2007-12-291-2/+2

* 1. Change use of "Cache" to "Default".Jim Laskey2006-08-011-2/+2
| | | | | | | | | | | 2. Added argument to instruction scheduler creators so the creators can do special things. 3. Repaired target hazard code. 4. Misc. More to follow. llvm-svn: 29450

* Changes For Bug 352Reid Spencer2004-09-011-1/+1
| | | | | | | | Move include/Config and include/Support into include/llvm/Config, include/llvm/ADT and include/llvm/Support. From here on out, all LLVM public header files must be under include/llvm/. llvm-svn: 16137

* Merging the linear scan register allocator in trunk. It currently passes ↵Alkis Evlogimenos2003-11-201-3/+6
| | | | | | most tests under test/Programs/SingleSource/Benchmarks/Shootout so development will continue on trunk. The allocator is not enabled by default. You will need to pass -regallo=linearscan to lli or llc to use it. llvm-svn: 10103
* Put all LLVM code into the llvm namespace, as per bug 109.Brian Gaeke2003-11-111-0/+4

* Moved enum and command-line option in separate file. Also added function ↵Alkis Evlogimenos2003-10-021-0/+35
