| | | | | | iSel may not be able to find corresponding Node for llvm.dbg.value during DAG construction. Make iSel's life easier by removing this distance between llvm.dbg.value and its value instruction. llvm-svn: 132151

* Mark tBX as an indirect branch rather than a return.Cameron Zwarich2011-05-262-9/+9
| | | | llvm-svn: 132107
* Test .seh_startchained and .seh_endchained parsing.Charles Davis2011-05-263-15/+18
| | | | | | | | | | | Rework how the MCWin64EHUnwindInfo instances are stored. Fix issues with chained unwind areas exposed by the test that were related to this. The ChainedParent field had the wrong address, because when the chained unwind info was added, the addresses shifted around. Now we store the pointers to the structures, which are now allocated from the MC heap. llvm-svn: 132106
* Correctly handle a one-word struct passed byval on x86_64.Stuart Hastings2011-05-264-15/+116

* indvars: incremental fixes for -disable-iv-rewrite and testcases.Andrew Trick2011-05-262-22/+138
| | | | | | | | Use a proper worklist for use-def traversal without holding onto an iterator. Now that we process all IV uses, we need complete logic for resusing existing derived IV defs. See HoistStep. llvm-svn: 132103
* Add a RAGreedy::canEvict function.Jakob Stoklund Olesen2011-05-251-4/+62
| | | | | | | | | | | | This doesn't change functionality (much), but it allows for a more fine-grained eviction policy. The current policy only compares spill weights, and that is not always the best thing to do. Spill weights are designed to serve linear scan, and they don't consider live range splitting. Add a mechanism so canEvict() can request that a live range be evicted and split/spilled. This is to avoid infinite eviction loops. llvm-svn: 132101
* Rewrite fast-isel integer cast handling to handle more cases, and to be ↵Eli Friedman2011-05-255-59/+205
| | | | | | | | | | simpler and more consistent. The practical effects here are that x86-64 fast-isel can now handle trunc from i8 to i1, and ARM fast-isel can handle many more constructs involving integers narrower than 32 bits (including loads, stores, and many integer casts). rdar://9437928 . llvm-svn: 132099

* Add tests for .seh_setframe and .seh_handlerdata parsing. Fix issues withCharles Davis2011-05-254-2/+40
| | | | | | | | | | them. I had to add a special SwitchSectionNoChange method to MCStreamer just for .seh_handlerdata. If this isn't OK, please let me know, and I'll find some other way to fix .seh_handlerdata streaming. llvm-svn: 132084

* Fix MSVC warning: "is out of range for enum constant" Francois Pichet2011-05-251-1/+1
| | | | | | | MSVC doesn't support 64 bit enum. OpcodeMask is not used anywhere in the code base. llvm-svn: 132057
* Fix some issues Duncan found in the previous commit.Rafael Espindola2011-05-252-4/+5
| | | | | | | | I kept the reference to the ABI since that is the common case. The -fno-asynchronous-unwind-tables option is a user controlled way of breaking the ABI. llvm-svn: 132053
