--- Comment #3 from jakub at gcc dot gnu dot org 2008-01-03 15:01 ---
Additionally, pass_tree_profile is executed multiple times with -fopenmp, e.g.
on
void foo (int i)
{
#pragma omp parallel
if (i > 2)
bar (i + 1);
else if (i < -2)
bar (i / 2);
else
bar (i * 2);
}
(which compiles) profile counters are added before omp expansion and once again
for the child function. Is there a reason why pass_tree_profile can't run
after
pass_cleanup_cfg/pass_init_datastructures/pass_expand_omp?
If it can't be moved, could it at least skip all edges in omp parallel regions?
Or if it is not thread safe, just disable pass_tree_profile if flag_openmp...

Also POINTER_PLUS_EXPR does not in any way change the issues we raised with undefinedness of overflow in pointer + offset expressions. Now, Joseph says > This bug is about the interpretation of GCC's internal representation, not > that of the standard. where yes, we seem to agreed to having an unsigned offset argument to POINTER_PLUS_EXPR which we need to interpret as a signed quantity. And in a different place we sort-of agreed to limit the maximum object size gcc handles to half of SIZE_T_MAX. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27214

I see the argument that this isn't a regression, but if I'm a user, and I read about the new feature, and I try it out, and things break, that seems bad.

I'm taking a look at how it might be done.
This allows compilation to proceed:

}

+ {

+ GFC_DECL_SUBREF_ARRAY_P (sym->backend_decl) = 1;

+ gfc_allocate_lang_decl (sym->backend_decl);
+ gfc_finish_var_decl (span, sym);
+ TREE_STATIC (span) = 1;
+ DECL_INITIAL (span) = build_int_cst (NULL_TREE, 0);
+
+ GFC_DECL_SPAN (sym->backend_decl) = span;
+ }
+
TREE_USED (sym->backend_decl) = 1;
if (sym->attr.assign && GFC_DECL_ASSIGN (sym->backend_decl) == 0)
{
but the span is not passed back to the actual argument, as this demonstrates:
MODULE test
IMPLICIT NONE
TYPE :: my_type
INTEGER :: value = 99
INTEGER :: spacer = 199
END TYPE
CONTAINS
SUBROUTINE get_values(values, d)
INTEGER,POINTER :: values(:)
TYPE(my_type),POINTER :: d(:)
values => d(:)%value
print *, "in get_values ", values
END SUBROUTINE
END MODULE
use test
TYPE(my_type),POINTER :: d(:)
INTEGER,POINTER :: values(:)
allocate (d(2))
call get_values (values, d)
print *, "in MAIN", values
deallocate (d)
end
I'll have to figure out how this can be done. No doubt 'span' will have to be
added to the parent scope and the assignment performed on function entry and
return. Hmmm!! Better still would be to copy in and copy out.
Back to PR34431 and friends - I'll do this next.

[Bug target/34628] [4.2/4.3 Regression] problems with inlining on ARM
--- Comment #4 from tbm at cyrius dot com 2008-01-03 18:03 ---
Bugzilla wraps the testcase in a way that some commented out is no longer
commented out and so you don't see the segfault. Here's the testcase again
with proper wrapping:
typedef unsigned short u16;
typedef unsigned char u8;
static void
do_segfault(u8 in_buf[], const u8 out_buf[], const int len)
{
int i;
for (i = 0; i < len; i++) {
//SSVAL(in_buf, 2*i, SVAL(out_buf,2*i)); // more or less just a
// byte-wise memcpy
asm("nop\n");
in_buf[2*i] = ( out_buf[2*i] | out_buf[(2*i)+1]<<8 ) & 0xFF;
// in_buf[2*i] = out_buf[2*i];
asm("nop\n");
in_buf[(2*i)+1] = ( out_buf[2*i] | out_buf[(2*i)+1]<<8 ) >> 8;
// in_buf[(2*i)+1] = out_buf[(2*i)+1];
asm("nop\n");
}
}
int main(int argc, char *argv[])
{
u8 outbuf[32] = "buffer ";
u8 inbuf[32] = "\f";
asm("nop\n");
do_segfault(inbuf, outbuf, 12);
asm("nop\n");
return 0;

[Bug target/34653] New: unnecessary REX prefix
for this code:
extern unsigned long table[];
unsigned long foo(unsigned char *p) {
unsigned long long tag = *p;
return table[tag >> 4];
}
gcc generates:
:
0: 0f b6 07movzbl (%rdi),%eax
3: 48 c1 e8 04 shr$0x4,%rax
7: 48 8b 04 c5 00 00 00mov0x0(,%rax,8),%rax
e: 00
b: R_X86_64_32S table
f: c3 retq
that "shr $0x4,%rax" would be better as "shr $0x4,%eax" because it produces the
same result (due to dominating movzbl) and it's one byte shorter which favours
both space and the narrow decoder on the core2.

[Bug target/34653] unnecessary REX prefix
--- Comment #1 from dean at arctic dot org 2008-01-03 19:27 ---
oops i should have used an "unsigned long" for the tag rather than unsigned
long long, not that it matters much.
here's an expanded example showing another unnecessary REX:
extern unsigned long table[];
unsigned long foo(unsigned char *p) {
unsigned long tag = *p;
return table[tag >> 4] + table[tag & 0xf];
}
which generates:
0: 0f b6 17movzbl (%rdi),%edx
3: 48 89 d0mov%rdx,%rax
6: 48 c1 ea 04 shr$0x4,%rdx
a: 83 e0 0fand$0xf,%eax
d: 48 8b 04 c5 00 00 00mov0x0(,%rax,8),%rax
14: 00
11: R_X86_64_32Stable
15: 48 03 04 d5 00 00 00add0x0(,%rdx,8),%rax
1c: 00
19: R_X86_64_32Stable
1d: c3 retq
and in this case the "mov %rdx,%rax" could be "mov %edx,%eax" because of the
dominating movzbl.

The missing increment of r4 seems to be the problem. Post-increment is created for r4, but it disappears in the combine pass. Does not seem to be loop optimizer related. -- rakdver at gcc dot gnu dot org changed: What|Removed |Added Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 Last reconfirmed|-00-00 00:00:00 |2008-01-03 21:23:36 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34628

--- Comment #16 from hubicka at gcc dot gnu dot org 2008-01-03 21:25 --- Subject: Bug 31081 Author: hubicka Date: Thu Jan 3 21:23:26 2008 New Revision: 131306 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=131306 Log: PR tree-optimization/31081 * tree-inline.c (remap_ssa_name): Initialize uninitialized SSA vars to 0 when inlining and not inlining to first basic block. (remap_decl): When var is initialized to 0, don't set default_def. (expand_call_inline): Set entry_bb. * tree-inline.h (copy_body_data): Add entry_bb.
