[llvm-commits] [PATCH] More closely match docs for CallSite::getCalledFunction

[Nick Sumner]

The documentation for CallSite::getCalledFunction is inconsistent with
what the function does. Without optimization, a direct call may be
made through a cast. This causes the function to return null even
though the call was direct. This is problematic for those of us using
LLVM in a context where we can't necessarily apply optimizations
before running our analyses.

Attached is a patch that simply calls stripPointerCasts on the called
value before converting it into a Function. I realize that handling
the general case may not be a priority, so alternatively, I could
submit a patch that makes the documentation more explicit about this
limitation.

thanks,
Nick Sumner
