git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57544 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-15Adjust whitespace in debug messages to be more consistentDan Gohman
with other debug messages. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57543 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-15- Add target lowering hooks that specify which setcc conditions are illegal,Evan Cheng
i.e. conditions that cannot be checked with a single instruction. For example, SETONE and SETUEQ on x86. - Teach legalizer to implement *illegal* setcc as a and / or of a number of legal setcc nodes. For now, only implement FP conditions. e.g. SETONE is implemented as SETO & SETNE, SETUEQ is SETUO | SETEQ. - Move x86 target over. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57542 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-14FastISel support for exception-handling constructs.Dan Gohman
- Move the EH landing-pad code and adjust it so that it works with FastISel as well as with SDISel. - Add FastISel support for @llvm.eh.exception and @llvm.eh.selector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57539 91177308-0d34-0410-b5e6-96231b3b80d8

Update LangRef to mention \xx quoting in names. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57538 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-14Change getLLVMName to use raw_ostream & PrintLLVMName.Daniel Dunbar
- Avoids duplicated quotification code. - Remove QuoteNameIfNeeded. - No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57537 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-14Fix command-line option printing to print two spaces where needed,Dan Gohman
instead of requiring all "short description" strings to begin with two spaces. This makes these strings less mysterious, and it fixes some cases where short description strings mistakenly did not begin with two spaces. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57521 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-14Combine (fcmp cc0 x, y) | (fcmp cc1 x, y) into a single fcmp when possible.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57515 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-14- Somehow I forgot about one / une.Evan Cheng
- Renumber fcmp predicates to match their icmp counterparts. - Try swapping operands to expose more optimization opportunities. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57513 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-13When doing the very-late shift-and address-mode optimization,Dan Gohman
create a new DAG node to represent the new shift to keep the DAG consistent, even though it'll almost always be folded into the address. If a user of the resulting address has multiple uses, the nodes may get revisited by a later MatchAddress call, in which case DAG inconsistencies do matter. This fixes PR2849. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57465 91177308-0d34-0410-b5e6-96231b3b80d8
