* Several fixes and enhancements to the PPC32 backend.Nate Begeman2004-10-071-1/+2
| | | | | | | | | | | | | | | | | | | | | | 1. Fix an illegal argument to getClassB when deciding whether or not to sign extend a byte load. 2. Initial addition of isLoad and isStore flags to the instruction .td file for eventual use in a scheduler. 3. Rewrite of how constants are handled in emitSimpleBinaryOperation so that we can emit the PowerPC shifted immediate instructions far more often. This allows us to emit the following code: int foo(int x) { return x | 0x00F0000; } _foo: .LBB_foo_0: ; entry ; IMPLICIT_DEF oris r3, r3, 15 blr llvm-svn: 16826

* Changes For Bug 352Reid Spencer2004-09-011-2/+2
| | | | | | | | Move include/Config and include/Support into include/llvm/Config, include/llvm/ADT and include/llvm/Support. From here on out, all LLVM public header files must be under include/llvm/. llvm-svn: 16137

* Stack space for argument passing is 32 regardless of 32- vs. 64-bit arch.Misha Brukman2004-08-191-6/+6

* On 64-bit PowerPC, pointers are 8 bytes, so parameter area offset is 48, not 24Misha Brukman2004-08-191-7/+10

* Clean up floating point instruction selection.Nate Begeman2004-08-191-44/+5
| | | | | | | | Change int->float cast code to put conversion constants in constant pool. Shorten code sequence for constant pool fp loads. Remove LOADLoDirect/LOADLoIndirect psuedo instructions and tweak asmwriter llvm-svn: 15913
