mips-sgi-irix6.5
>Description:
A number of g77 tests fail on mips-sgi-irix6.5 using -mabi=64.  The error is 

Internal compiler error in function_arg, at config/mips/mips.c:4007

The tests that fail are:
 g77.f-torture/compile/20000511-2.f
 g77.f-torture/compile/980310-3.f
 g77.f-torture/compile/19990905-2.f
 g77.f-torture/execute/19981119-0.f
 g77.f-torture/execute/20010116.f

The failures occur at all levels of optimisation.  The failures were introduced between 20010501 and 20010507.  I have not been able to narrow the interval as gcc would not bootstrap on irix in over this period.

 
>How-To-Repeat:
bootstrap and run testsuite with -mabi=64

 I some more information on this.  I strongly suspect that the patch that =
 causes the problem is:
 
 2001-05-03 Alexandre Oliva <aoliva@redhat.com>
 Re-installed 2001-01-09's patch:
 * hwint.h (HOST_BITS_PER_WIDE_INT, HOST_WIDE_INT): Use long long
 if it's wider than long and the target's long is wider than the
 host's.=20
 
 
 See http://gcc.gnu.org/ml/gcc-bugs/2001-05/msg00112.html, which suggests =
 that may expose latent bugs for 32-bit > 64-bit cross-compilation - =
 exactly the problem we are seeing - and suggests some fixes.  The patch =
 went in at 2001-05-03 11:58:43 UTC, and broke irix bootstrap.  A gcc =
 from just prior does not fail the tests. =20

 Hi,
 
 the problems from PR 3392 can be reduced a little.
 There seems to be a problem with two-dimensional arrays:
 
 Just try to compile the following code with "g77 -mabi=3D64" (you don't
 even need optimization for this reduced example):
       subroutine f(n,a)
       integer n
       real a(n,n)
       end
 This will cause an ICE with gcc 3.1 on mips-sgi-irix6.5. You can also
 use "complex" or "double precision" instead of "real".
 
 Greetings,
 Volker Reichelt
