[Bug target/35100] New: [4.3 regression] internal compiler error: in extract_insn, at recog.c:1990

[debian-gcc at lists dot debian dot org]

seen with trunk 20080202, works with g77. Compiling without -mlongcall
succeeds.

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?

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?

------- 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:

                (const_int 0 [0x0]))
            (use (const_int 8 [0x8]))

Just adding the version information of gcc:

lisbon [Manu] : gcc -v
Using built-in specs.
Target: powerpc-linux-gnu
Configured with: ../src/configure -v

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.
