2007-09-26Make temporaries explicit to avoid prematureDale Johannesen
destruction of compiler-created ones. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42383 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-12Revise previous patch per review comments.Dale Johannesen
Next round of x87 long double stuff. Getting close now, basically works. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41875 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-11Add APInt interfaces to APFloat (allows directlyDale Johannesen
access to bits). Use them in place of float and double interfaces where appropriate. First bits of x86 long double constants handling (untested, probably does not work). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41858 91177308-0d34-0410-b5e6-96231b3b80d8

2007-09-06Next round of APFloat changes.Dale Johannesen
Use APFloat in UpgradeParser and AsmParser. Change all references to ConstantFP to use the APFloat interface rather than double. Remove the ConstantFP double interfaces. Use APFloat functions for constant folding arithmetic and comparisons. (There are still way too many places APFloat is just a wrapper around host float/double, but we're getting there.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41747 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-09Patch 10 for long double. Doing constants right needs expanding ConstantFPDale Johannesen
to handle values bigger than double. If we assume host==target and host long double works correctly, this is not too bad, but we don't want to have that limitation longterm. I could implement accepting double constants as long double or something like that, which would lead to incorrect codegen with no errors; the more I think about that the worse it seems. Rather than do such a hack that would be backed out later, I'm settling for giving reasonable error messages, for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40974 91177308-0d34-0410-b5e6-96231b3b80d8

2007-05-05Implement support for globally associating abbrevs with block IDs, whichChris Lattner
relieves us from having to emit the abbrevs into each instance of the block. This shrinks kc.bit from 3368K to 3333K, but will be a more significant win once instructions are abbreviated.
