2006-01-16For PR411:Reid Spencer
This patch is an incremental step towards supporting a flat symbol table. It de-overloads the intrinsic functions by providing type-specific intrinsics and arranging for automatically upgrading from the old overloaded name to the new non-overloaded name. Specifically: llvm.isunordered -> llvm.isunordered.f32, llvm.isunordered.f64 llvm.sqrt -> llvm.sqrt.f32, llvm.sqrt.f64 llvm.ctpop -> llvm.ctpop.i8, llvm.ctpop.i16, llvm.ctpop.i32, llvm.ctpop.i64 llvm.ctlz -> llvm.ctlz.i8, llvm.ctlz.i16, llvm.ctlz.i32, llvm.ctlz.i64 llvm.cttz -> llvm.cttz.i8, llvm.cttz.i16, llvm.cttz.i32, llvm.cttz.i64 New code should not use the overloaded intrinsic names. Warnings will be emitted if they are used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25366 91177308-0d34-0410-b5e6-96231b3b80d8

2006-01-13If inlining a call to a function that contains dynamic allocas, wrap theChris Lattner

2006-01-13Use ClonedCodeInfo to avoid another walk over the inlined code, this thisChris Lattner
time in common C cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25285 91177308-0d34-0410-b5e6-96231b3b80d8
2006-01-13Use the ClonedCodeInfo object to avoid scans of the inlined code whenChris Lattner
it doesn't contain any calls. This is a fairly common case for C++ code, so it will probably speed up the inliner marginally in these cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25284 91177308-0d34-0410-b5e6-96231b3b80d8

2006-01-13Fix a bug I noticed by inspection: if the first instruction in the inlinedChris Lattner
function was not an alloca, we wouldn't check the entry block for any allocas, leading to increased stack space in some cases. In practice, allocas are almost always at the top of the block, so this was never noticed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25280 91177308-0d34-0410-b5e6-96231b3b80d8

2005-11-18Implement a refinement to the mem2reg algorithm for cases where an allocaChris Lattner
has a single def. In this case, look for uses that are dominated by the def and attempt to rewrite them to directly use the stored value. This speeds up mem2reg on these values and reduces the number of phi nodes inserted. This should address PR665. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24411 91177308-0d34-0410-b5e6-96231b3b80d8

2005-10-27Move some constant folding code shared by Analysis and Transform passesJohn Criswell
into the LLVMAnalysis library. This allows LLVMTranform and LLVMTransformUtils to be archives and linked with LLVMAnalysis.a, which provides any missing definitions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24036 91177308-0d34-0410-b5e6-96231b3b80d8

SparcV9 JIT. 2. Make LLVMTransformUtils a relinked object file and always link it before LLVMAnalysis.a. These two libraries have circular dependencies on each other which creates problem when building the SparcV9 JIT. This change fixes the dependency on all platforms problems with a minimum of fuss. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24023 91177308-0d34-0410-b5e6-96231b3b80d8

2005-10-23When a function takes a variable number of pointer arguments, with a zeroJeff Cohen
pointer marking the end of the list, the zero *must* be cast to the pointer type. An un-cast zero is a 32-bit int, and at least on x86_64, gcc will not extend the zero to 64 bits, thus allowing the upper 32 bits to be random junk. The new END_WITH_NULL macro may be used to annotate a such a function so that GCC (version 4 or newer) will detect the use of un-casted zero at compile time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23888 91177308-0d34-0410-b5e6-96231b3b80d8
