[LLVMdev] Initializing GC roots
Hello all,
I set: InitRoots = true; in my gc plugin as i want the roots to be
initialized to the "null" value.
Is there a way to define which value should be the initial one? For
example, i would like to initialize my roots to -5 (tagged, null value
for the GC in my runtime system) instead of 0.
Ofcourse, i could d...

[LLVMdev] Function inlining creates uninitialized stack roots
Sure. I think we can change the GC lowering pass to recognize all
llvm.gcroot (not only the ones in the first block), and move them to the
first block so that they are initialized by the pass later on.
