* Split -enable-finite-only-fp-math to two options:Evan Cheng2010-07-1511-38/+39
| | | | | | -enable-no-nans-fp-math and -enable-no-infs-fp-math. All of the current codegen fp math optimizations only care whether the fp arithmetics arguments and results can never be NaN. llvm-svn: 108465
* build/Darwin: Add a missing directory dependency.Daniel Dunbar2010-07-151-1/+1
| | | | llvm-svn: 108463
* remove some unneeded overloads that were causing Chris Lattner2010-07-151-20/+0
| | | | | | ambiguity problems on some systems. llvm-svn: 108462
* fix the definitions of ConstTextCoalSection/ConstDataCoalSectionChris Lattner2010-07-152-4/+5
| | | | | | | | | | | to keep "Text" in sync with the "pure instructions" section attribute. Lack of this attribute was preventing the assembler from emitting multibyte noops instructions for templates (and inlines, and other coalesced stuff) and was causing the assembler to mismatch .o files. This fixes rdar://8018335 llvm-svn: 108461
* fix indentation and 80 colsChris Lattner2010-07-151-2/+3

* Don't merge uses when they are targetting fixup sites withDan Gohman2010-07-151-1/+20
| | | | | | | | | | | | | different widths. In a use with a narrower fixup, formulae may be wider than the fixup, in which case the high bits aren't necessarily meaningful, so it isn't safe to reuse them for uses with wider fixups. This fixes PR7618, though the testcase is too large for a reasonable regression test, since it heavily dependes on hitting LSR's heuristics in a certain way. llvm-svn: 108455
* fix the encoding of MMX_MOVFR642Qrr, it starts with 0xF2 not 0xF3,Chris Lattner2010-07-151-1/+1
| | | | | | | | this fixes rdar://8192860. Unfortunately it can only be triggered with llc because llvm-mc matches another (correctly encoded) version of this, so no testcase. llvm-svn: 108454
* Use dbgs() instead of errs() in a DEBUG.Dan Gohman2010-07-151-1/+1

* Teach ScalarEvolution how to fold trunc(undef) and anyext(undef) to undef.Dan Gohman2010-07-151-0/+14
| | | | | | This helps LSR behave more consistently on bugpoint-reduced testcases. llvm-svn: 108451
* Use std::vector instead of TargetRegisterInfo::FirstVirtualRegister.Bill Wendling2010-07-151-2/+3
| | | | llvm-svn: 108450
* Use std::vector instead of TargetRegisterInfo::FirstVirtualRegister. This timeBill Wendling2010-07-153-18/+24

* Speculatively revert r108429 to fix the clang self-host.Owen Anderson2010-07-152-19/+28

* Per Chris' suggestion, get rid of the select canonicalization and just addOwen Anderson2010-07-152-28/+19
| | | | | | | | the corresponding or-icmp-and pattern. This has the added benefit of doing the matching earlier, and thus being less susceptible to being confused by earlier transforms. llvm-svn: 108429
* Remove unneeded check, and correct style.Owen Anderson2010-07-151-3/+2

* Watch out for a constant offset cancelling out a base register, formingDan Gohman2010-07-152-2/+53
| | | | | | | a zero. This situation arrises in Fortran code with induction variables that start at 1 instead of 0. This fixes PR7651. llvm-svn: 108424
* Reapply r108378, with bugfixes, testcase, and improved comment formatting.Owen Anderson2010-07-153-0/+62
| | | | | | This now passes LIT, nighty test, and llvm-gcc bootstrap on my machine. llvm-svn: 108422

| | | | | | certain this is the best fix; the code immediately above looks confused, as it first checks to see if we are NOT on Darwin and then checks the Darwin version number. This fix allows c-index-test (in Clang) to run outside of running the regression test suite. I would appreciate if someone reviewed this. llvm-svn: 108416
* Fix PR7647, handling the case when 'To' ends up being Chris Lattner2010-07-152-14/+81
| | | | | | | | | | mutated by recursive simplification. This also enhances ReplaceAndSimplifyAllUses to actually do a real RAUW at the end of it, which updates any value handles pointing to "From" to start pointing to "To". This seems useful for debug info and random other VH users. llvm-svn: 108415
