* Add parsing for the Thumb t_addrmode_s4 addressing mode. This can almostBill Wendling2010-11-304-14/+89
| | | | | | | | | | certainly be made more generic. But it does allow us to parse something like: ldr r3, [r2, r4] correctly in Thumb mode. llvm-svn: 120408
* ptx: add ld instructionChe-Liang Chiou2010-11-303-9/+118
| | | | | | | support register and register-immediate addressing mode todo: immediate and register-register addressing mode llvm-svn: 120407
* Rewrite the main DSE loop to be written in terms of reasoningChris Lattner2010-11-301-77/+106
| | | | | | | | | | | | | | about pairs of AA::Location's instead of looking for MemDep's "Def" predicate. This is more powerful and general, handling memset/memcpy/store all uniformly, and implementing PR8701 and probably obsoleting parts of memcpyoptimizer. This also fixes an obscure bug with init.trampoline and i8 stores, but I'm not surprised it hasn't been hit yet. Enhancing init.trampoline to carry the size that it stores would allow DSE to be much more aggressive about optimizing them. llvm-svn: 120406
* Rewrite mwait and monitor support and custom lower arguments.Eric Christopher2010-11-303-4/+75
| | | | | | Fixes PR8573. llvm-svn: 120404
* Add a puts optimization that converts puts() to putchar('\n').Anders Carlsson2010-11-301-3/+30
| | | | llvm-svn: 120398
* rename a function and reduce some indentation, no functionality change.Chris Lattner2010-11-301-19/+21
| | | | llvm-svn: 120391
* Stub out a new LiveDebugVariables pass.Jakob Stoklund Olesen2010-11-304-0/+109
| | | | | | | | | | | | | This analysis is going to run immediately after LiveIntervals. It will stay alive during register allocation and keep track of user variables mentioned in DBG_VALUE instructions. When the register allocator is moving values between registers and the stack, it is very hard to keep track of DBG_VALUE instructions. We usually get it wrong. This analysis maintains a data structure that makes it easy to update DBG_VALUE instructions. llvm-svn: 120385
* remove the pointless check of MemoryUseIntrinsic fromChris Lattner2010-11-301-3/+0
| | | | | | | is trivially dead, since these have side effects. This makes the (misnamed) MemoryUseIntrinsic class dead, so remove it. llvm-svn: 120382
* strength reduce this.Chris Lattner2010-11-301-1/+1
| | | | llvm-svn: 120381
* getLocationForDest should work for memset as well.Chris Lattner2010-11-301-1/+1
| | | | llvm-svn: 120380
* rename doesClobberMemory -> hasMemoryWrite to be more specific, andChris Lattner2010-11-301-11/+11
| | | | | | remove an actively-wrong comment. llvm-svn: 120378
* clean up handling of 'free', detangling it from everything else.Chris Lattner2010-11-301-22/+22
| | | | | | | It can be seriously improved, but at least now it isn't intertwined with the other logic. llvm-svn: 120377
* Minor cleanups. No functional change.Bill Wendling2010-11-301-24/+23
| | | | llvm-svn: 120372
* s/ARM::BRIND/ARM::BX/g to coincide with r120366.Bill Wendling2010-11-303-5/+5
| | | | llvm-svn: 120371
* enhance basicaa to return "Mod" for a memcpy call when theChris Lattner2010-11-301-0/+5
| | | | | | queried location doesn't overlap the source, and add a testcase. llvm-svn: 120370
* Add correct encoding for "bl __aeabi_read_tp". However, the asm matcher isn'tBill Wendling2010-11-301-3/+5
| | | | | | able to match this yet. llvm-svn: 120369
* Teach basicaa that memset's modref set is at worst "mod" and neverChris Lattner2010-11-302-7/+14
| | | | | | | | | | contains "ref". Enhance DSE to use a modref query instead of a store-specific hack to generalize the "ignore may-alias stores" optimization to handle memset and memcpy. llvm-svn: 120368
* Rename BX/BRIND/etc patterns to clarify which is actually the BX instructionJim Grosbach2010-11-302-9/+9
| | | | | | and which are pseudos. llvm-svn: 120366
* Add some encoding for the adr instruction. Labels still need to be finished.Bill Wendling2010-11-301-6/+16
| | | | llvm-svn: 120365
* Correct Thumb2 encodings for a much wider range of loads and stores.Owen Anderson2010-11-304-48/+96
| | | | llvm-svn: 120364
* my previous patch would cause us to start deleting some volatileChris Lattner2010-11-301-1/+1

* Make a few more ARM pseudo instructions actually use the PseudoInst base class.Jim Grosbach2010-11-301-14/+13
| | | | llvm-svn: 120362
* Predicate encoding should be withing {}s. And general cleanup.Bill Wendling2010-11-302-8/+4

* Predicate encoding should be withing {}s.Bill Wendling2010-11-301-2/+2
| | | | llvm-svn: 120360
* two changes to DSE that shouldn't affect anything:Chris Lattner2010-11-301-58/+28
| | | | | | | | | | | | | | 1. Don't bother trying to optimize: lifetime.end(ptr) store(ptr) as it is undefined, and therefore shouldn't exist. 2. Move the 'storing a loaded pointer' xform up, simplifying the may-aliased store code. llvm-svn: 120359
* Fix the encoding of VLD4-dup alignment.Bob Wilson2010-11-304-37/+67
| | | | | | | | The only reasonable way I could find to do this is to provide an alternate version of the addrmode6 operand with a different encoding function. Use it for all the VLD-dup instructions for the sake of consistency. llvm-svn: 120358
* Rename VLDnDUP instructions with double-spaced registersBob Wilson2010-11-301-12/+12
| | | | | | in an attempt to make things a little more consistent. llvm-svn: 120357
* Add support for NEON VLD3-dup instructions.Bob Wilson2010-11-306-1/+104
| | | | | | The encoding for alignment in VLD4-dup instructions is still a work in progress. llvm-svn: 120356
