I'd like to be able to use GCC's `__builtin_alloca` without the C
standard library.
This seems to work:
--- core/stdc/stdlib.d
module core.stdc.stdlib;
extern(C) void* alloca(size_t n) pure;
---
...but, since I'm not actually using the C standard library, I'd
prefer to avoid creating that module hierarchy.
I tried simply adding...
--- {anyfile}.d
extern extern(C) void* __builtin_alloca(size_t size) pure;
---
... to my existing files, but I get an undefined reference for
`__bulitin_alloca`.
LDC was pretty straightforward with:
--- {anyfile}.d
pragma(LDC_alloca)
void* alloca(size_t size) pure;
---
Is there a way to do something like that in GDC. I don't care if
I have to use `__builtin_alloca` or some other identifier, I just
don't want to create the C standard library module hierarchy.
Thanks,
Mike
