------- Comment #2 from reichelt at gcc dot gnu dot org 2007-12-27 20:38 -------
Confirmed. Here's a reduced testcase that crashes when compiled under
i686-pc-linux-gnu:
=========================================
typedef double* va_list;
void __builtin_va_start(va_list, ...);
void foo(const char* s, ...)
{
va_list v;
__builtin_va_start(v, s);
}
=========================================
bug.c: In function 'foo':
bug.c:8: internal compiler error: in convert_move, at expr.c:371
Please submit a full bug report, [etc.]
I don't know whether messing around with va_list and __builtin_va_start
is allowed or not. Btw, with
typedef void* va_list;
instead of
typedef double* va_list;
I get a different ICE:
bug.c: In function 'foo':
bug.c:8: internal compiler error: in simplify_subreg, at simplify-rtx.c:4918
Please submit a full bug report, [etc.]
Btw, the ICE appeared in GCC 4.0.0 (GCC 3.3.x crashed, too).

------- Comment #3 from mmitchel at gcc dot gnu dot org 2008-01-02 23:20 -------
This code isn't valid. We probably shouldn't allow declarations of
__builtin_va_start, and we certainly shouldn't allow declarations that don't
match the internal definition -- and I don't think that declaration does. (I'm
not sure we should allow definitions of any __builtin functions; after all
they're built-in!)

I think the frontend should reject identifiers in declarations that touch
the __builtin_ namespace.
The regression status is dubious (it probably 'regressed' at the point
the builtin was introduced).

Apparently glibc used it only for 2 builtins in include/stdio.h and it seemed
to be probably a workaround from back in 2003, I've verified it is unnecessary
with gcc 4.1/4.3/4.4 and removed it. Current glibc trunk compiles with rth's
patch just fine. Therefore I'm removing my objection. Can we proceed with
this for 4.4 then?

The patch as is already rejects typedef double *__builtin_va_list;, so it is
just
{struct,union,enum} __builtin_foo that isn't rejected on the C side, which we
could reject (disallow that in pushtag?), but isn't fatal, given that GCC
internally never uses struct __builtin_*, always just uses __builtin_*
typedefs.
On the C++ side, it is more work probably.

Patch at:
http://gcc.gnu.org/ml/gcc-patches/2008-11/msg00644.html
Ian Taylor's review:
I'm not really comfortable with breaking the building of old version
of glibc just to fix an ice-on-invalid. I'll approve this for gcc
4.5, to give people more time to update their glibc.
So, moving to 4.5.0 target.
