On systems where GFC_IO_INT is 8 bytes and requires 8 byte alignment the
st_parameter_dt structure may be out of sync between the fortran library and
compiler because the common field of st_parameter_dt is 28 bytes long (if
pointers and ints are 4 bytes each) and the next field (rec) is of type

@jason: Thanks for you comment.
I am adding Mark in CC to the bug so that we can close the bug in WONTFIX
eventually, it you both agree :-)

The comment in the test says:
/* Make sure we didn't eliminate casted types because we thought they were
unused. */
If we don't want to do that any more, I think we can just remove this test,

been useful in retrospect. :-/

split_constant_offset does not handle correctly the offset of
s.c[1] as this is an ADDR_EXPR whose op0 was set by
extract_ops_from_tree to itself, an ADDR_EXPR. Now this code
is not handled in split_constant_offset_1

What was said in bug 37838 but not here is that -frounding-math sometimes fixes
the problem. So, I was suggesting that -frounding-math should be enabled by
default.

No, ADDR_EXPRs are single because they can have an arbitrary number of operands
(think of a_1-b[i_2][j_3] which has three operands, a_1, i_2 and j_3). In
your case it is a is_gimple_min_invariant, which may add to

IMHO the fix for the tuplification bug(!) is to strip the ADDR_EXPR that is
always present on op0 in split_constant_offset_1 so:
case ADDR_EXPR:
{
tree base, poffset;
HOST_WIDE_INT

The default of -fno-rounding-math is chosen with the reason that this is what
a compiler can assume if #pragma STDC FENV_ACCESS is not turned on.
What you may request instead is an implementation of FENV_ACCESS

The C standard doesn't require a compiler to
Functions with more than 72 arguments, pass char/short arguments 73 and higher
in the wrong position in the quadword stored on the stack. This is due to the
char/short not being at offset 0 of the word (char/short are stored in the
bottom of the first int in the quadword).

Thanks for taking a look at this problem. Your patch mentioned
in #3 fixes the test case in #1 on sh64. Even with it, there
are similar failures with -O0 in the result of the gcc testsuite
on sh64-linux.
