2006-07-12Change the callgraph representation to store the callsite along with theChris Lattner
target CG node. This allows the inliner to properly update the callgraph when using the pruning inliner. The pruning inliner may not copy over all call sites from a callee to a caller, so the edges corresponding to those call sites should not be copied over either. This fixes PR827 and Transforms/Inline/2006-07-12-InlinePruneCGUpdate.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29120 91177308-0d34-0410-b5e6-96231b3b80d8

2006-04-10Add a simple pass to make sure that all (non-library) calls to malloc and freeAndrew Lenharth
are visible to analysis as intrinsics. That is, make sure someone doesn't pass free around by address in some struct (as happens in say 176.gcc). This doesn't get rid of any indirect calls, just ensure calls to free and malloc are always direct. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27560 91177308-0d34-0410-b5e6-96231b3b80d8

2006-01-22Make this more efficient in the following ways:Chris Lattner
1. Do not statically construct a map when the program starts up, this is expensive and cannot be optimized. Instead, create a list. 2. Do not insert entries for all function in the module into a hashmap that lives the full life of the compiler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25512 91177308-0d34-0410-b5e6-96231b3b80d8
2006-01-22Several non-functionality changing changes:Chris Lattner
1. Use the varargs version of getOrInsertFunction to simplify code. 2. remove #include 3. Reduce the number of #ifdef's. 4. remove extraneous vertical whitespace. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25508 91177308-0d34-0410-b5e6-96231b3b80d8
2006-01-19For PR696:Reid Spencer
Don't do floor->floorf conversion if floorf is not available. This checks the compiler's host, not its target, which is incorrect for cross-compilers Not sure that's important as we don't build many cross-compilers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25456 91177308-0d34-0410-b5e6-96231b3b80d8

2006-01-19Don't internalize llvm.global[cd]tor unless there are uses of it. ThisChris Lattner
unbreaks front-ends that don't use __main (like the new CFE). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25429 91177308-0d34-0410-b5e6-96231b3b80d8

2006-01-14Let the inliner update the callgraph to reflect the changes it makes, insteadChris Lattner
of doing it ourselves. This fixes Transforms/Inline/2006-01-14-CallGraphUpdate.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25321 91177308-0d34-0410-b5e6-96231b3b80d8

2005-12-13Improve ResolveFunctions to:Reid Spencer
a) use better local variable names (OldMT -> OldFT) where "M" is used to mean "Function" (perhaps it was previously "Method"?) b) print out the module identifier in a warning message so that it is possible to track down in which module the error occurred. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24698 91177308-0d34-0410-b5e6-96231b3b80d8

2005-11-05Add support alignment of allocation instructions.Nate Begeman

2005-10-24Only build .a file versions of these libraries, instead of .a and .o versions.Chris Lattner
This should speed up build times. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23933 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
2005-10-18Add an option to this pass. If it is set, we are allowed to internalizeChris Lattner
all but main. If it's not set, we can still internalize, but only if an explicit symbol list is provided. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23783 91177308-0d34-0410-b5e6-96231b3b80d8
