[llvm-commits] Erlang/HiPE prologue

[Yiannis Tsiouris]

Hi,

This is the 2nd patch we would like to submit upstream in order to add
proper support for Erlang.

The scenario that this patch tries to address is:

HiPE (native-)compiled Erlang functions have some code prepended to the
asm generated that computes how large a stack frame it will need for a
function, then compares that with the minimum available size that the
calling convention guarantees, and if the needed size is larger than the
guaranteed available size, it calls a BIF ("inc_stack_0").

Is this "good" enough to be pushed upstream?


Best,
Yiannis
