2008-04-08Add -disable-required-unwind-tables to testsDale Johannesen
that need it (usually, grepping for some string found in unwind info) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49364 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-31Mark functions in some tests as 'nounwind'. GeneratingDale Johannesen
EH info for these functions causes the tests to fail for random reasons (e.g. looking for 'or' or counting lines with asm-printer; labels count as lines.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49003 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-19Fix live variables issues:Evan Cheng
1. If part of a register is re-defined, an implicit kill and an implicit def are added to denote read / mod / write. However, this should only be necessary if the register is actually read later. This is a performance issue. 2. If a sub-register is being defined, and it doesn't have a previous use, do not add a implicit kill to the last use of a super-register: = EAX, AX<imp-use,kill> ... AX = In this case, EAX is live but AX is killed, this is wrong and will cause the coalescer to do bad things. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48521 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-11Generalize ExpandIntToFP to handle the case where the operand is legalDan Gohman
and it's the result that requires expansion. This code is a little confusing because the TargetLoweringInfo tables for [US]INT_TO_FP use the operand type (the integer type) rather than the result type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48206 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-03This is the initial check-in for adding register scavenging to PPC. (Currently,Bill Wendling
PPC-64 doesn't work.) This also lowers the spilling of the CR registers so that it uses a register other than the default R0 register (the scavenger scrounges for one). A significant part of this patch fixes how kill information is handled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47863 91177308-0d34-0410-b5e6-96231b3b80d8

and was causing aborts with the new APInt changes. This may also be fixing an obscure ppc64 bug. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47692 91177308-0d34-0410-b5e6-96231b3b80d8
