* Disable the leaf function optimization, which is apparently not legal onChris Lattner2003-10-141-25/+2
| | | | | | | | | X86/linux. :( The problem is that a signal delivered while the function is executing could clobber the functions stack. This is a partial fix for PR41. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9113 91177308-0d34-0410-b5e6-96231b3b80d8

* * Spell "necessary" correctlyChris Lattner2003-10-122-6/+48
| | | | | | | | | | | | * Print floating point values using C99 hexadecimal style FP if possible. This increases the number of floating point constants that may be emitted inline, and improves precision for global variable initializers which can not be emitted in integer form. This fixes the Olden/Power benchmark with the CBE!!!! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9052 91177308-0d34-0410-b5e6-96231b3b80d8
* * Be TBAA safeChris Lattner2003-10-122-64/+118
| | | | | | | | | | | * Fix isFPCSafeToPrint to find more constants safe to print, which it was failing because ftostr was padding with leading space characters. * Scan the entire module for global constants instead of each function at a time. This has the advantage of allowing us to emit constants at global scope instead of function scope. This speeds FP programs quite a bit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9048 91177308-0d34-0410-b5e6-96231b3b80d8

* Convert PhyRegAlloc into a proper pass.Brian Gaeke2003-09-212-132/+98
| | | | | | | | | | | | | | | | | | | | | | | PhyRegAlloc.cpp: Don't include TargetMachine.h or TargetRegInfo.h, because these are provided by PhyRegAlloc.h. Merge class RegisterAllocator into class PhyRegAlloc. Simplify & move ctor, dtor to PhyRegAlloc.h. Make some of PhyRegAlloc's reference members into pointer members, so they can be more easily messed with. MarkAllocatedRegs() becomes a member method, with fewer args. PhyRegAlloc.h: Include Pass.h, TargetMachine.h and TargetRegInfo.h. Don't declare TargetRegInfo forward. Give AddedInstrns the obvious clear() method. Make some of PhyRegAlloc's reference members into pointer members, so they can be more easily messed with. Add prototype for markAllocatedRegs().
