Hi David
I've tried compiling with and without BRAINDEAD_API, but I can't get it to hit
the breakpoint. The following is my GDB breakpoint (just to confirm I have the
right function):
(gdb) info breakpoints
Num Type Disp Enb Address What
1 breakpoint keep y 0xb54bef60 in
CodeGenLexicalScope::LoadValueOfTypeAtOffsetFromObject(char const*, char
const*, char const*, unsigned int, llvm::Value*) at
/home/chris/etoile/Etoile/Languages/LanguageKit/CodeGen/CodeGenLexicalScope.cpp:12
Cheers
Chris
