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

2004-11-14If a function always returns a constant, replace all calls sites with thatChris Lattner
constant value. This makes the return value dead and allows for simplification in the caller. This implements IPConstantProp/return-constant.ll This triggers several dozen times throughout SPEC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17730 91177308-0d34-0410-b5e6-96231b3b80d8
2004-11-11Actually, leave the check in. This prevents us from counting dead argumentsChris Lattner
as IPCP opportunities. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17680 91177308-0d34-0410-b5e6-96231b3b80d8

2004-11-10Make IP Constant prop more aggressive about handling self recursive calls.Chris Lattner
This implements IPConstantProp/recursion.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17666 91177308-0d34-0410-b5e6-96231b3b80d8
2004-11-09Do not let dead constant expressions hanging off of functions prevent IPCP.Chris Lattner
This allows to elimination of a bunch of global pool descriptor args from programs being pool allocated (and is also generally useful!) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17657 91177308-0d34-0410-b5e6-96231b3b80d8
2004-09-20'Pass' should now not be derived from by clients. Instead, they should deriveChris Lattner
from ModulePass. Instead of implementing Pass::run, then should implement ModulePass::runOnModule. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16436 91177308-0d34-0410-b5e6-96231b3b80d8

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/. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16137 91177308-0d34-0410-b5e6-96231b3b80d8
