2005-03-15This mega patch converts us from using Function::a{iterator|begin|end} toChris Lattner
using Function::arg_{iterator|begin|end}. Likewise Module::g* -> Module::global_*. This patch is contributed by Gabor Greif, thanks! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20597 91177308-0d34-0410-b5e6-96231b3b80d8
2004-10-07Several fixes and enhancements to the PPC32 backend.Nate Begeman
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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16826 91177308-0d34-0410-b5e6-96231b3b80d8
