           Summary: __builtin_apply_args also broken on mips irix 6.5 ?
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: pierre dot nguyen-tuong at asim dot lip6 dot fr
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: mips-sgi-irix6.5
  GCC host triplet: mips-sgi-irix6.5
GCC target triplet: mips-sgi-irix6.5

__builtin_apply_args fails to put float arguments on the stack

Works fine on Linux, g++ 3.3.1
Seems to fail on mips-sgi-irix6.5, g++ 3.3 (N32 and 64 ABI)
Also fails on Solaris 2.9 gcc 3.3.1 (see bug #12503, confirmed)

Example:
- funcA is a variadic function
- funcB is a normal function
- funcA is called and should give all its arguments to funcB thanks to
__builtin_apply_args and __builtin_apply

main -> funcA(args) -> funcB(args)

Note: arguments are put in correct order in the stack, but float (double)
arguments are set to 0.0

Compile file demo.cpp with g++ -Wall -o demo demo.cpp for N32 or
g++ -Wall -mabi=64 -mips4 -o demo demo.cpp for N64 and run ./demo

Tested on SGI Octane R10000, Irix 6.5.16f, g++ 3.3

__builtin_apply is indeed broken.

Very likely fixed by http://gcc.gnu.org/ml/gcc-patches/2003-10/msg00897.html but
I can't assert it.
