[LLVMdev] qsort callbacks portability issues
Hi,
there are a couple of possible issues around array_pod_sort
from STLExtras.h .
Firstly, qsort() needs a comparator that returns zero on equal
inputs. ConstantIntSortPredicate in SimplifyCFG.cpp (where
the sort is being used to bring duplicate values together)
fails this requirement. All the others look ok.
Secondly, on Windows qsort() needs its callback to use __cdecl
calling convention, which won't be the case by default if
LLVM is being built with e.g. __fastcall...
