This is probably an old issue but why no builtin_malloc
../tests-c/20071018-1.c:14:8: error: use of unknown builtin
'__builtin_malloc'
[-Wimplicit-function-declaration]
*f = __builtin_malloc(sizeof(struct foo));
Both of your questions are clang questions, you should ask on cfe-dev. -Chris On Oct 1, 2013, at 8:26 PM, reed kotler <rkotler at mips.com> wrote:> This is probably an old issue but why no builtin_malloc > > ../tests-c/20071018-1.c:14:8: error: use of unknown builtin '__builtin_malloc' > [-Wimplicit-function-declaration] > *f = __builtin_malloc(sizeof(struct foo)); > > _______________________________________________ > LLVM Developers mailing list > LLVMdev at cs.uiuc.edu http://llvm.cs.uiuc.edu > http://lists.cs.uiuc.edu/mailman/listinfo/llvmdev

I have some other builtin issues I've found.

It will always be a library function, even if the compiler can optimise it away in some cases. It makes no sense to provide it as externally visible builtin. Joerg
