I've come across the following whilst trying to build a gcc cross-compiler:
/
-isystem
/ -isystem
/ -g -DIN_GCC
-DCRSS_CMPILE -W -Wall -Wwrite-strings -Wstrict-prototypes
-Wmissing-prototypes -Wold-style-definition -isystem ./include -fPIC -g
-DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLAT_NT_NEEDED -Dinhibit_libc -I.
-I. -I//gcc/gcc -I//gcc/gcc/. -I//gcc/gcc//include
-I/libdecnumber -DL_divsc3 -fvisibility=hidden -DHIDE_EXPRTS -c
//gcc/gcc/libgcc2.c -o libgcc/./_divsc3.o
//gcc/gcc/libgcc2.c: In function ‘__divsc3’:
//gcc/gcc/libgcc2.c:1910: internal compiler error: in
default_secondary_reload, at targhooks.c:532
The compiler sources were pulled by Subversion from the gcc repository:

The binutils tools being used were:

And the tools necessary for the compiler can be obtained from:

in a huge tarball with lots of other stuff from:
I've reproduced this problem compiling gcc on on an SMP i686 box and a UP
x86_64 box. both boxes the native compiler was installed from the
gcc-4.1.1-1.fc5 Fedora Core 5 RPMs:
warthog>gcc -v
Using built-in specs.
Target: x86_64-redhat-linux
Configured with: /configure /usr /usr/share/man
/usr/share/info
,c++,objc,obj-c++,java,fortran,ada
/
Thread model: posix
gcc version 4.1.1 20060525 (Red Hat 4.1.1-1)
warthog255>ssh hades gcc -v
Using built-in specs.
Target: i386-redhat-linux
Configured with: /configure /usr /usr/share/man
/usr/share/info
,c++,objc,obj-c++,java,fortran,ada
/
Thread model: posix
gcc version 4.1.1 20060525 (Red Hat 4.1.1-1)
The partially built gcc claims its version to be:
warthog>./gcc/xgcc -v
Using built-in specs.
Target: frv-linux-gnu
Configured with: /gcc/configure /opt/frv-4.1
/opt/frv-4.1/frv-linux-gnu/bin/
/
Thread model: posix
gcc version 4.2.0 20060803 (experimental)
I configured the package with the configuration line you can see above and
then just ran "make".
The intermediate compiler can be used to trigger the bug with following
command line:
./gcc/xgcc -B./gcc -c wibble.c -o wibble.o
from within the build directory. wibble.c is the attached preprocessed and
stripped down version of libgcc2.c.
Note that adding:
#define __builtin_expect(X, Y) (X)
to the top of the file seems to make the problem go away.

Created an attachment (id=12004)

Stripped down testcase for the bug

I get the error on line 92 of this source file:

warthog>./gcc/xgcc -B./gcc -c wibble.c -o wibble.o
wibble.c: In function ‘__divsc3’:
wibble.c:92: internal compiler error: in default_secondary_reload, at
targhooks.c:532
Please submit a full bug report,
with preprocessed source if appropriate.
See <for instructions.

Confirmed.

Comment #3 from pinskia at gcc dot gnu dot org 2006-08-08 01:30
gcc_assert (insn_data[(int) icode].n_operands == 3);
(define_expand "reload_incc"
[(parallel [(set (match_operand:CC 2 "integer_register_operand" "=&d")
(match_operand:CC 1 "memory_operand" "m"))
(clobber (match_scratch:CC_CCR 3 ""))])
(parallel [(set (match_operand:CC 0 "icc_operand" "=t")
(match_dup 2))
(clobber (match_scratch:CC_CCR 4 ""))])]

I never thought reload could handle more than 3 operands for reload_inM before.

FRV is not a primary or secondary target.

Comment #5 from mmitchel at gcc dot gnu dot org 2007-05-14 22:28
Will not be fixed in 4.2.0; retargeting at 4.2.1.
