LLVM runtime for gallium

[Robert Swindells <rjs%fdy2.co.uk@localhost>]

Is anyone working on getting the correct LLVM object files built into
the gallium module ?

My first guess at a solution would be to add conditional code to LLVM
itself, at least for the Itanium and MachO references.

Trying to link against the gallium module directly I get this:

Where mesa.c is this:

#include <stdio.h>

int main(int argc, char *argv[])
{
        extern void __driDriverGetExtensions_r600(void);

        __driDriverGetExtensions_r600();
}
