[llvm-commits] [PATCH] Add malloc call utility functions

[Dan Gohman]

Hi Victor,

If MallocHelper is going to replace MallocInst, how will it support
-fno-builtins?  With MallocInst, one at least had the option of
omitting the RaiseAllocations pass (though it seems llvm-gcc and
clang don't actually do this, which is a bug). With MallocHelper,
how can -fno-builtins be implemented?
