* 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 Lattner2010-11-302-2/+18
| | | | | | 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 Lattner2010-11-303-7/+28
| | | | | | | | | | 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
* Added a feature where registers can be referred toSean Callanan2010-11-305-8/+197
| | | | | | | | | | | using special $-variables from expressions. (lldb) expr $rip These variables are available for reading and writing. llvm-svn: 120367
* 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 Anderson2010-11-305-48/+111
| | | | llvm-svn: 120364
* my previous patch would cause us to start deleting some volatileChris Lattner2010-11-302-1/+21
| | | | | | stores, fix and add a testcase. llvm-svn: 120363
* 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
| | | | llvm-svn: 120361
* 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 Wilson2010-11-305-37/+68
| | | | | | | | 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 Wilson2010-11-307-1/+127
| | | | | | The encoding for alignment in VLD4-dup instructions is still a work in progress. llvm-svn: 120356

* Nuke trailing whitespace.Jim Grosbach2010-11-291-3/+3
| | | | llvm-svn: 120344
