------- Comment #2 from rguenth at gcc dot gnu dot org 2008-02-06 21:09 -------
The testcase works for me with a cross from x86_64, but - you mention g77 but
this is C preprocessed source. Is it the correct testcase?

This works for me on the trunk, I don't get an ICE.

------- Comment #5 from steven at gcc dot gnu dot org 2008-02-13 22:04 -------
I also can't reproduce it (neither on native nor with a cross).

Any local patches? Maybe you can reduce it to a set of simpler configuration
options?

Default internal compiler error: in extract_insn, at recog.c:1990

------- Comment #6 from manus at eiffel dot com 2008-04-28 22:34 -------
I can reproduce this problem with gcc 4.2.3 that comes with Ubuntu 8.04 on
PowerPC with the following command line:

gcc -Wall -mlongcall -fPIC -c foo.c

Removing either `-fPIC' or `-mlongcall' succeeds, it is when used together that
it fails with:

lisbon [Manu] : gcc -Wall -mlongcall -fPIC -c foo.c
foo.c: In function 'idrf_reset_pos':
foo.c:23: error: unrecognizable insn:
(call_insn 10 9 12 3 (parallel [
(call (mem:SI (symbol_ref:SI ("idr_setpos") [flags 0x1]
<function_decl 0x48169700 idr_setpos>) [0 S4 A8])
(const_int 0 [0x0]))
(use (const_int 8 [0x8]))
(clobber (scratch:SI))
]) -1 (nil)
(nil)
(expr_list:REG_DEP_TRUE (use (reg:SI 30 30))
(expr_list:REG_DEP_TRUE (use (reg:SI 4 4))

(nil)))))
foo.c:23: internal compiler error: in extract_insn, at recog.c:2077
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
For Debian GNU/Linux specific bug reporting instructions,
see <URL:file:///usr/share/doc/gcc-4.2/README.Bugs>.


where foo.c is simply:
#include <stdlib.h>

typedef struct idr {
int i_op;
size_t i_size;
char *i_buf;
char *i_ptr;
} IDR;

typedef struct idrs {
IDR i_encode;
IDR i_decode;
} IDRF;

void idr_setpos(IDR *idrs, size_t pos)
{
}

void idrf_reset_pos(IDRF *idrf)
{
idr_setpos(&idrf->i_encode, 0);
idr_setpos(&idrf->i_decode, 0);
}

------- Comment #7 from manus at eiffel dot com 2008-04-29 04:51 -------
Just adding the version information of gcc:

lisbon [Manu] : gcc -v
Using built-in specs.
Target: powerpc-linux-gnu
Configured with: ../src/configure -v
--enable-languages=c,c++,fortran,objc,obj-c++,treelang --prefix=/usr
--enable-shared --with-system-zlib --libexecdir=/usr/lib
--without-included-gettext --enable-threads=posix --enable-nls
--with-gxx-include-dir=/usr/include/c++/4.2 --program-suffix=-4.2
--enable-clocale=gnu --enable-libstdcxx-debug --enable-objc-gc --enable-mpfr
--disable-softfloat --enable-secureplt
--enable-targets=powerpc-linux,powerpc64-linux --with-cpu=default32
--with-long-double-128 --enable-checking=release --build=powerpc-linux-gnu
--host=powerpc-linux-gnu --target=powerpc-linux-gnu
Thread model: posix
gcc version 4.2.3 (Ubuntu 4.2.3-2ubuntu7)

It would be nice to reopen the case since it is definitely reproducible.

Reopening as this looks related to secureplt.
