The original insn 13 was

(insn 13 12 14 3 (set (reg:SI 193)
(plus:SI (subreg:SI (reg:QI 191 [ MEM[(char *)buf1_4(D) + 4B] ]) 0)
(subreg:SI (reg:QI 192 [ MEM[(char *)buf0_1(D) + 5B] ]) 0)))

and RA chooses r1 and r0 as the registers to where memories will
be loaded.  The problem is we have no direct way to load buf1[4]
to r1.  In such situation, a secondary reload is needed.  See
the description of TARGET_SECONDARY_RELOAD in the gcc manual.
Here is a trial:

asmcons and ira pass log for the reload failure of "z" insn constraint

(In reply to comment #5)

Yes, it is very much.

> Although the reload issue beyonds me,
> .ira dump file about that impossible insn which doesn't satisfy

I've been trying to make some sense out of it since, but I'm a bit clueless at
the moment here.

The following function is a reduced failure example:

int fail (char* buf0, char* buf1)
{
  char a,b,c;

  a = buf0[0] + buf1[1];
  b = buf0[5] + buf1[4];
  c = buf0[15] + buf1[14];
  return a+b-c;
}

In the attached log the problematic pseudo reg is reg:QI 191, where it is
reloaded into r1... 

Reloads for insn # 13
Reload 0: reload_in (QI) = (reg:QI 191 [ MEM[(char *)buf1_4(D) + 4B] ])
reload_out (SI) = (reg:SI 1 r1 [193])
GENERAL_REGS, RELOAD_OTHER (opnum = 0)


Strange thing is that the following variant does not cause the error:

int fail (char* buf0, char* buf1, char* out)
{
  char a,b,c;

  a = buf0[0] + buf1[1];
  b = buf0[5] + buf1[4];
  c = buf0[15] + buf1[14];
  *out = a+b-c;
  return *out;
}

The gcc  Makefile has

LIBICONV = /usr/lib/libiconv.dylib
LIBICONV_DEP =

LIBICONV is subsequently used in the LIBS variable.

it works just fine but the objective C compiler does not get installed. Seems
to be an issue with the GC.

I am compiling for ARM using Ubuntu x64 so maybe that has something to do with

Excellent, just for completeness, I can confirm that on my machines :

does reproduce the problem identically and that :
   gfortran -O3 -mno-avx -march=native
compiles successfully.

Your gcc -v information?

I use i686-w64-mingw32 gfortran 4.6.2 to run the test well on Win7 intel core2.

I've just done a quick rebuild of tree-emutls.o and cc1plus on Tru64

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50875

 Bug #: 50875
   Summary: O3 and -march=native lead to internal compiler error:
in find_reloads
Classification: Unclassified
   Product: gcc
   Version: 4.6.1
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: holyj...@gmail.com


Created attachment 25618
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25618
Stripped down test case.

It appears that for certain combinations of array allocations, conditionals and
loops, gfortran 4.6 and 4.7 give :
"internal compiler error: in find_reloads, at reload.c:4067",
but only when paired with -O3 and -march=native.

Tried compiling against 4.6.1 and 4.7.0 20111010 (experimental) [trunk revision
179769]. It works against 4.4.6 and 4.5.4.

I tried on two Sandy-Bridge systems, an i7 with Scientific Linux and an i5 with
Ubuntu 11.10 and Mac OS X (Only tried 4.6 on this platform), which all gave the
same behaviour.

I have attached a completely stripped down test case (doesn't do anything
meaningful) which works against 4.5 and 4.4 but not later versions for the
described flags. The output of this when compiled against the earlier versions
is:
 (-6.6689347635125245, -3.4315183934768561)
(-0.21071909368227187,-0.21353560926074711)
 (-2.3118973846843422, -1.1895930430719770)
(-3.7929436862808936,-3.8436409666934486).
NB. spaces stripped out.

For the moment, I am working around this by compiling the offending module with
-O2, which works.

Hope this helps, if you need any more information, please ask.

Regards,
Joly.

KLUDGE/workaround for ICE

I worked around the ICE on AIX with this patch.  THIS IS A WORKAROUND ONLY--I
do not know the code anywhere near well enough to believe this is a correct
fix.

It changes tree-emutls.c so that a weak symbol remains public, which then lets
it go through the assert in ipa.c.

Rename loc_t to lincol_t

SVN Trunk revision 180430 fails to compile on AIX 5.3 TL4, with this error:

/mnts/cdstools/build/source/gcc-r180430/gcc/tree-diagnostic.c:59: error:
conflicting types for ‘loc_t’

Grepping around the system headers, I find a typedef struct localeinfo_table to
loc_t in /usr/include/sys/localedef31.h.  I've verified this is present in AIX
5.3 TL4, 6.1 and 7.3.

As the use of 'loc_t' is isolated to tree-diagnostic.c, I simply renamed it to
'lincol_t' so I could get on with things.  I've attached the diff, but someone
is far more than welcome to come up with a better name that doesn't conflict
with AIX.  (Or someone could make it so AIX never appears in my life again,
that would work too.)

Yes, thanks for spotting it.  Ideally we'd define this_thread::yield() anyway,
but until then the test should use the dg-require

Shouldn't the testcase contain:

// { dg-require-sched-yield "" }

?  I'm getting a failure because this_thread::yield is not defined, and
30_threads/this_thread/2.cc contains this directive so as to not fail in the
same way.

Yes they are. Not doing that would be a good idea
