[LLVMdev] Memory Dependence Analysis: getNonLocalDependency()
Hi, I have a question about the memory dependence analysis. I am trying to use it to selectively enumerate a set of pairs of (load, store) instructions for every function by calling getNonLocalDependency() on the MemoryDependenceAnalysis. This populates a DenseMap<BasicBlock*, Value*>. I just looked up an usage of this in GVN.cpp: MD->getNonLocalDependency(C, deps); for

[LLVMdev] nonlocal go to -- how?
The languages I'm faced with compiling in the near future have nonlocal go to statements and nested procedures. A procedure gets implemented as a structure containing its entry point and an environment pointer. It is easy enough to call its entry point and pass the environment pointer as an extra argument (rather like the pointer to this or self in object-oriented code). It's no

You want to return to a previous activation record (pascal speak) or stack frame? If yes, then yes, EH will do that for you. You'll want to understand what EH is in detail and how to map the semantics you want

[LLVMdev] Memory Dependence Analysis: getNonLocalDependency()
Thanks for the quick reply, Owen. I went through the code in MemoryDependenceAnalysis.cpp again. Since DenseMap<BasicBlock*, Value*> maps a BasicBlock to a single Value (Instruction) and it is populated by a DFS on the reverse Control Flow Graph starting at the query instruction's block, is it correct to say that the last dependent instruction in each visited basic block is what is

[LLVMdev] MemoryDependenceAnalysis Bug or Feature?
Sorry, I misunderstood the question. The difference between a load and a read-only call is that load can be used as the value of the memory location. E.g. DeadStoreElimination pass removes a store that stores a just loaded value back into the same location. To do this it checks if the stored value is the value of load. Read-only call cannot be used like this. This being said, I don't know if

[LLVMdev] Why does "uwtable" prevent optimizing Invoke -> Call?
Hi, in r176827 the optimization that turns invokes with empty landing pads into plain calls was disabled for invocations of function with the "uwtable" attribute. But given this code: struct S { ~S() {}; }; void blackbox(); __attribute__((__noinline__)) void inner() { blackbox(); } int foo() { S s; inner(); return 0; } int bar() {
