* llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin2009-07-141-7/+7
| | | | | | | | | This adds location info for all llvm_unreachable calls (which is a macro now) in !NDEBUG builds. In NDEBUG builds location info and the message is off (it only prints "UREACHABLE executed"). llvm-svn: 75640
* Begin the painful process of tearing apart the rat'ss nest that is ↵Owen Anderson2009-07-131-1/+1
| | | | | | | | | Constants.cpp and ConstantFold.cpp. This involves temporarily hard wiring some parts to use the global context. This isn't ideal, but it's the only way I could figure out to make this process vaguely incremental. llvm-svn: 75445
* assert(0) -> LLVM_UNREACHABLE.Torok Edwin2009-07-111-6/+6
| | | | | | | | | Make llvm_unreachable take an optional string, thus moving the cerr<< out of line. LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for NDEBUG builds. llvm-svn: 75379
* Convert more assert(0)+abort() -> LLVM_UNREACHABLE,Torok Edwin2009-07-111-1/+2

* Second installment of "BasicBlock operands to the back"Gabor Greif2009-03-132-2/+2
| | | | | | | | | | | | | | | | | | changes. For InvokeInst now all arguments begin at op_begin(). The Callee, Cont and Fail are now faster to get by access relative to op_end(). This patch introduces some temporary uglyness in CallSite. Next I'll bring CallInst up to a similar scheme and then the uglyness will magically vanish. This patch also exposes all the reliance of the libraries on InvokeInst's operand ordering. I am thinking of taking care of that too. llvm-svn: 66920

| | | | | | | | | | | | | | | | when a readonly declaration is called, set a flag. This is faster and uses less memory. In theory it is less accurate, because before only those internal globals that were read by someone were being marked "Ref", but now all are.

* Correct callgraph construction. It has two problems:Duncan Sands2008-09-091-34/+14
| | | | | | | | | | | | | | | | | | | (1) code left over from the days of ConstantPointerRef: if a use of a function is a GlobalValue then that is not considered a reason to add an edge from the external node, even though the use may be as an initializer for an externally visible global! There might be some point to this behaviour when the use is by an alias (though the code predated aliases by some centuries), but I think PR2782 is a better way of handling that. (2) If function F calls function G, and also G is a parameter to the call, then an F->G edge is not added to the callgraph. While this doesn't seem to matter much, adding such an edge makes the callgraph more regular. In addition, the new code should be faster as well as simpler. llvm-svn: 55987

* When PruneEH turned an invoke into an ordinaryDuncan Sands2008-09-061-1/+14
| | | | | | | | | | | | call (thus changing the call site) it didn't inform the callgraph about this. But the call site does matter - as shown by the testcase, the callgraph become invalid after the inliner ran (with an edge between two functions simply missing), resulting in wrong deductions by GlobalsModRef. llvm-svn: 55872

* Delete the removeCallEdgeTo callgraph method,Duncan Sands2008-09-051-10/+0
| | | | | | | | | | | | | | | because it does not maintain a correct list of callsites. I discovered (see following commit) that the inliner will create a wrong callgraph if it is fed a callgraph with correct edges but incorrect callsites. These were created by Prune-EH, and while it wasn't done via removeCallEdgeTo, it could have been done via removeCallEdgeTo, which is an accident waiting to happen. Use removeCallEdgeFor instead. llvm-svn: 55859
