| | | | llvm-svn: 116744
* Make AliasSetTracker TBAA-aware, enabling TBAA-enabled LICM.Dan Gohman2010-10-184-40/+85
| | | | llvm-svn: 116743
* Relocate with .bss instead of using the symbol. Matches gas behavior.Rafael Espindola2010-10-182-0/+28
| | | | llvm-svn: 116741

| | | | | | Patch by Alexander Herz! llvm-svn: 116733
* Add TypeBasedAliasAnalysis to the standard pass lists. Note that itDan Gohman2010-10-182-5/+13
| | | | | | is currently inert by default. llvm-svn: 116732
* Run tbaa before basicaa, since that's how it's expected to be used.Dan Gohman2010-10-181-1/+1
| | | | llvm-svn: 116731
* Fix BasicAA to pass TBAAInfo through to the chained analysis.Dan Gohman2010-10-181-26/+47
| | | | llvm-svn: 116730
* For Thumb2, try to use frame pointer references for stack slots even when aJim Grosbach2010-10-181-2/+10
| | | | | | base register is available. rdar://8525298 llvm-svn: 116729
* Produce ELF::R_386_GOTPC relocations.Rafael Espindola2010-10-183-1/+18
| | | | llvm-svn: 116728
* Make TypeBasedAliasAnalysis default to doing nothing, with a command-lineDan Gohman2010-10-182-1/+11
| | | | | | option to enable it. llvm-svn: 116722
* Use chaining in TypeBasedAliasAnalysis::pointsToConstantMemory.Dan Gohman2010-10-181-1/+4
| | | | llvm-svn: 116721
* Make BasicAliasAnalysis a normal AliasAnalysis implementation whichDan Gohman2010-10-1881-91/+115
| | | | | | | | | | | | does normal initialization and normal chaining. Change the default AliasAnalysis implementation to NoAlias. Update StandardCompileOpts.h and friends to explicitly request BasicAliasAnalysis. Update tests to explicitly request -basicaa. llvm-svn: 116720
* Make the bots happy.Rafael Espindola2010-10-181-1/+3
| | | | llvm-svn: 116719
* Added a handful of x86-32 instructions that were missing so that llvm-mc wouldKevin Enderby2010-10-185-1/+124
| | | | | | | | | | be more complete. These are only expected to be used by llvm-mc with assembly source so there is no pattern, [], in the .td files. Most are being added to X86InstrInfo.td as Chris suggested and only comments about register uses are added. Suggestions welcome on the .td changes as I'm not sure on every detail of the x86 records. More missing instructions will be coming. llvm-svn: 116716
* Produce a R_386_PLT32 when needed. Moved the default cases of switches to theRafael Espindola2010-10-182-10/+26

* ARM addrmode4 instructions (ldm, stm and friends) can't encode an immediateJim Grosbach2010-10-181-1/+2
| | | | | | | | offset for stack references. Make sure we take that into account when deciding whether to reserver an emergency spill slot for the register scavenger. rdar://8559625 llvm-svn: 116714
* Grammar tweak.Jim Grosbach2010-10-181-1/+1
| | | | llvm-svn: 116712
* Handle GOTOFF correctly on i386.Rafael Espindola2010-10-182-5/+35
| | | | llvm-svn: 116711
* Trivial grammar tweak.Jim Grosbach2010-10-181-1/+1
| | | | llvm-svn: 116710
* Improve lowering of sext to i128 on SPU.Kalle Raiskila2010-10-182-2/+10
| | | | | | | | The old algorithm inserted a 'rotqmbyi' instruction which was both redundant and wrong - it made shufb select bytes from the wrong end of the input quad. llvm-svn: 116701

* Add a MCObjectFormat class so that code common to all targets that use aRafael Espindola2010-10-1612-63/+194
