[Bug c++/16635] g++ instantiates templates at the wrong place
--- Additional Comments From geoffk at gcc dot gnu dot org 2005-04-26

Here's the same thing with overloaded functions, causing a wrong-code error.
If the last definition of
'bar' is commented out, the testcase passes, but otherwise not.
template class T int func(T x)
{
return bar (x);
}
int bar(const int x)
{
return x;
}
extern C void abort ();
int main (void)
{
int x = 3;
if (funcint(x) != 3)
abort ();
}
int bar (int x)
{
return x + 3;
}

Also, maybe we should also change consistently collate_CharT::do_hash (in locale_facets.tcc) which is also not perfect, but at least doesn't depend on the size of size_t.

[Bug target/21195] SSE intrinsics not inlined, sometimes.
--- Additional Comments From tbptbp at gmail dot com 2005-04-26 12:45

Let's have some more fun.
Take the silly testcase up there, add this:
struct foo_t {
bool dummy;
__attribute__ ((always_inline)) foo_t() {}
};
change finalblow into that:
bool finalblow(const __m128 a, const __m128 b, const __m128 c, const __m128 d,
const __m128 e, const __m128 f) {
foo_t bar[4];
return bar[0].dummy
bloatit(a,b) bloatit(c,d) bloatit(e,f) bloatit(a,c)
bloatit(b,d) bloatit(c,e) bloatit(d,f);
}
and with the same compiler flags you'll get this interesting snippet, from
finalblow:
...
4005ea: data16 -- sure that loop deserves to be aligned
4005eb: data16
4005ec: nop
4005ed: data16
4005ee: data16
4005ef: nop
4005f0: inc%eax
4005f2: cmp$0x4,%eax
4005f5: jne4005f0 finalblow(float __vector, float __vector, float
__vector, float __vector, float __vector, float __vector)+0x40
...
In case you're wondering, yes that's the constructor.
Again, that testcase is a bit artificial.
But i've just spent an hour tracking what was producing such an interesting
aligned empty loop in my app: same symptoms, but triggered differently; the
constructor was empty and not always_inline, but apparently some treshold was
met (lots of inlining around) and tada... instant contribution to the global
warming for peanuts :)
I'm certainly not qualified, but i'll dare to say that something's fishy wrt
inlining.

It can always be calculated from the bounds and the stride, in any case. Most of the operations where speed is of the essence will do the indexing in the same way as matmul.

[Bug libfortran/20930] [4.0 Regression] gfortran.dg/backspace.f execution test
--- Additional Comments From dje at gcc dot gnu dot org 2005-04-26 18:33 --- The problem is due to libgfortran not flushing the record length marker to the file. transfer.c:next_record_w() copies the record length into the buffer, but does not ensure that the buffer gets flushed to the file. At a later point, libgfortran seeks past the file position and then back, which the UNIX standard allows the OS to fill with zeroes. next_record_w() calls sfree(), but sfree() specifically does not flush the buffer if operating on the small_buffer in the unix_stream structure or the stream is buffered. Presumably when switching from writing to reading, the buffer should be flushed. The call to REWIND sets the mode to reading and truncates the file before the call to flush in data_transfer_init() could occur. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20930

--- Additional Comments From pinskia at gcc dot gnu dot org 2005-04-26 19:51 --- The problem comes from dce but the problem is that IV OPT is making the pointer as unsigned int *, because the field's type is just unsigned int[] but since the orginal type of the struct is volatile, we don't have a vop as it is volatile store. And since IV opts just copies the vops and not run aliasing (which right now causes a different issue on 4.0 branch), we don't get a vop. -- What|Removed |Added Summary|[4.0 Regression] Generates |[4.0/4.1 Regression] |wrong code (w/ optimization)|Generates wrong code (w/ |when copying data from a|optimization) when copying |table to a table in a |data from a table to a table |structure |in a structure http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21171

[Bug c/21159] [4.0/4.1 Regression] no effect warning despite cast to void*
--- Additional Comments From jsm28 at gcc dot gnu dot org 2005-04-26 21:55 --- What's actually happening is that GCC 4 is building trees for comma expressions in accordance with how the C standard says they are parsed, where previous versions were not. (void)a, (void)b, c is parsed as ((void)a, (void)b), c rather than as (void)a, ((void)b, c). The choice of internal representation should make no difference to the code generated but as here it can affect diagnostics. The diagnostic does seem useless here where the left-hand side of the expression is a comma expression with the right-hand side cast to void, so I'll add that as a case for which the diagnostic is disabled. -- What|Removed |Added AssignedTo|unassigned at gcc dot gnu |jsm28 at gcc dot gnu dot org |dot org | Status|NEW |ASSIGNED Last reconfirmed|2005-04-22 11:23:13 |2005-04-26 21:55:59 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21159

23:07 ---
Confirmed, reduced testcase:
int g(long long a, long long b)
{
a -= b;
return !a;
}
You were looking at the wrong function as we inline a function into
cryptcompress_truncate which
causes this.
One issue is when we go and expand (a - b) == 0, we expand it to cmpdi for some
reason instead of
inlining cmpdi.
