We die while looking for an array descriptor for the vector subscript:
/* For vector array subscripts we want the size of the vector. */
vecss = ss;
while (vecss->data.info.ref->u.ar.dimen_type[dim] == DIMEN_VECTOR)
{
vecss = vecss->data.info.subscript[dim];
gcc_assert (vecss && vecss->type == GFC_SS_VECTOR);
/* Get the descriptors for the vector subscripts as well. */
if (!vecss->data.info.descriptor)
gfc_conv_ss_descriptor (&loop->pre, vecss, !loop->array_parameter);
dim = vecss->data.info.dim[0];
}
But gfc_conv_ss_descriptor starts with:
static void
gfc_conv_ss_descriptor (stmtblock_t * block, gfc_ss * ss, int base)
{
gfc_se se;
tree tmp;
/* Get the descriptor for the array to be scalarized. */
gcc_assert (ss->expr->expr_type == EXPR_VARIABLE);
gfc_init_se (&se, NULL);
That assert triggers. For my small test case, the expr_type is EXPR_ARRAY
and for the maxloc test case it is EXPR_FUNCTION.

Well...
int
tree_expr_nonnegative_p (tree t)
{
...
CASE_BUILTIN_F (BUILT_IN_FREXP)
...
/* Always true. */
return 1;
Which the manpage of frexp seems to support:
DESCRIPTION
The frexp() function is used to split the number x into a normalized
fraction and an exponent which is stored in exp.
RETURN VALUE
The frexp() function returns the normalized fraction. If the argument
x is not zero, the normalized fraction is x times a power of two, and
is always in the range 1/2 (inclusive) to 1 (exclusive). If x is zero,
then the normalized fraction is zero and zero is stored in exp.
so, we just fold away the fabs. Your libm is broken. And:
src/tests> ./test_frexp
q: -123.456 a: 0.9645 e: 7
q: -123.456 a: 0.9645 b: -0.9645 e: 7
though why b is negative here, contradicting the manpage, is unclear to me.

Hi.
The following code, that used to compile on the older gcc,
now rejects:
---
static char var;
int main()
{
asm volatile ("" :: "i"(&var + 1));
return 0;
}
---
with the following message:
---
asc.c:5: warning: asm operand 0 probably doesnt match constraints
asc.c:5: error: impossible constraint in asm
---
Changing "+1" to "+0" makes it to compile again.

--- Additional Comments From pinskia at gcc dot gnu dot org 2005-08-02 18:57 --- Confirmed, this is because we "inline" the value of j and then remove the variable but for some reason dwarf-2 emits debuging info. This is unit-at-a-time problem as you can reproduce it on the 3.4 branch by adding -funit-at-a-time -O0 -gstabs+ and you will not get the debug info. You know what is better is just move to dwarf-2 instead for ppc-darwin. -- What|Removed |Added CC||pinskia at gcc dot gnu dot ||org Severity|normal |minor Status|UNCONFIRMED |NEW Component|debug |c++ Ever Confirmed||1 Keywords||wrong-debug Last reconfirmed|-00-00 00:00:00 |2005-08-02 18:57:31 date|| Summary|[C++] debug info omitted for|[4.0/4.1 Regression] [C++] |global const variables |debug info omitted for ||global const variables Target Milestone|--- |4.0.2 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23205

"It works in DWARF mode" is not a good excuse to ignore stabs while making various changes in the compiler. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23205

--- Additional Comments From pinskia at gcc dot gnu dot org 2005-08-02 19:02 --- I forgot to mention this works just fine for dwarf-2 because we emit the debug info even though the variable is not emitted. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23205

The improved aliasing was not reverted though which is what gets most of the improvements and not the promote statics pass. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20367
