[LLVMdev] MCSymbol and DebugLoc

[nicolas geoffray]

Hi all,

When emitting GC information, it can be very useful to emit the debug
location of a GC point, represented as a MCSymbol. Infortunately I haven't
found any API (JIT and codegen) where I can get from a MCSymbol to a
DebugLoc. Does that interface exist? If not, I plan on committing  a small
change in the GC code where the debug location is passed to the constructor
of a GC point. Patch attached.

Cheers,
Nicolas
