[LLVMdev] gcroot intrinsic

[Anderson, Todd A]

Okay.  Thanks.  I got past that problem and on to the next.

I've been trying to create a loadable GC module.  I used the example makefile in the LLVM GC doc.  This is with llvm-2.9 and Cygwin 1.7.9.  make reports that the compile succeeded and that it was linking a release loadable module with a dll extension.  However, when you look in the Release directory, all that is there is a .o file.

I have the LOADABLE_MODULE variable set to 1 in the makefile.  It is also strange that it was complaining about unresolved references during the link step...shouldn't those be resolved at load time?

Thanks,

Todd

When I add a call to @llvm.gcroot, it is consistently acting like it doesn't know what that function is.  I'm just getting started so it is probably something small and simple but some googling didn't yield much in the  way of an answer.  Any help is appreciated.


Ø  Intrinsic functions still need declarations. If you take a look at http://llvm.org/docs/LangRef.html#int_gcroot and copy the declaration listed under "syntax" to the top of your .ll file, then it will assemble with llvm-as.
