...ith the noreturn attribute so an unreachable is not inserted after a call to it? Does llvm-gcc keep a list of functions somewhere that it thinks do not return?

...ting function call"? Is it one with the "noreturn" attribute? if so, the assembly language docs say that program behavior is undefined if such a function ever returns. If your function could possibly return, it needs to not have that attribute.

Hello all, LLVM inserts unreachable instructions after every call to a terminating function. Is there a way to disable this feature so that it treats terminating function calls like any other function call, so the unreachable instruction would not be inserted? Unfortunately, simply removing the unreachable instructions after the fact would not suffice for my needs because I need to preserve the

Hello, Does the LLVM Andersens alias analysis handle function pointers precisely? I ran it and it looks like it says every function points points to the universal set. Is this what I should expect?

Hello, How do I download the poolalloc module for llvm 2.3?

...int it handled function pointers. As chris says, it's buggy and probably broken. Some function pointers also do point to the universal set (like global function pointers).

Might I suggest the following patch, because this issue has bite me too? You're lured in by the initial good results from the Andersens alias analysis, only to discover the bugs later on.
