2009-07-20Remove the code that tried to evaluate whether (A pred B) is knownDan Gohman
by determining if (B pred (B-A)) is known, as it doesn't handle overflow correctly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76504 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-20Make sure a global matching asm 'i' constraint gets itsDale Johannesen
flags set properly. (hasMemory is clearly irrelevant when matching 'i', I don't understand what this was supposed to be doing.) gcc.apple/asm-block-25.c (test passed before by accident, but generated code was wrong) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76503 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-20Move stripping of bitcasts in inline asm argumentsDale Johannesen
to a place where it affects everything. Occurs only on calls AFAIK. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76502 91177308-0d34-0410-b5e6-96231b3b80d8

humans can understand it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76480 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-20Pass in the unfortunately named "LessPrivatePrefix" for theBill Wendling
"LinkerPrivatePrefix". It seems to have been used in only one place before I started this "linker_private" business. I'm thinking that a rename is in order... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76479 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-20Use TII->findCommutedOpIndices to find the commute operands (rather than ↵Evan Cheng
guessing). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76472 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-20Change the casting of linkage types into a map. This makes this much more robustBill Wendling
as it no longer depends upon two different enums being kept in sync with each other. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76465 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-20Clarify that OverflowingBinaryOperator is not used for SDiv, even thoughDan Gohman
SDiv is a binary operation that can overflow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76464 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-20Removed the DumpSymbolsandMacros and LoadSymbolsandMacros MCStreamer API asKevin Enderby
the parsing of the .dump and .load should be done in the assembly parser and not have any need for an MCStreamer API. Changed the code for now so these just produce an error saying these specific directives are not yet implemented since they are likely no longer used and may never need to be implemented. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76462 91177308-0d34-0410-b5e6-96231b3b80d8

resulting interval's register class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76458 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-20Revert the addition of hasNoPointerOverflow to GEPOperator.Dan Gohman
Getelementptrs that are defined to wrap are virtually useless to optimization, and getelementptrs that are undefined on any kind of overflow are too restrictive -- it's difficult to ensure that all intermediate addresses are within bounds. I'm going to take a different approach. Remove a few optimizations that depended on this flag. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76437 91177308-0d34-0410-b5e6-96231b3b80d8
