Package: gcc-4.0
Version: 4.0.2-7
Severity: important
Hi,
When building clisp on amd64, I'm getting the following error:
gcc -W -Wswitch -Wcomment -Wpointer-arith -Wimplicit -Wreturn-type -Wmissing-d
eclarations -Wno-sign-compare -O -DUNICODE -DDYNAMIC_FFI -DDYNAMIC_MODULES -I.
-fPIC -I.. -c calls.m.c -o calls.o
calls.c: In function 'get_block':
calls.c:843: error: unrecognizable insn:

(insn_list:REG_DEP_TRUE 172 (nil))
(expr_list:REG_DEAD (reg:DI 133)

(nil))))
calls.c:843: internal compiler error: in extract_insn, at recog.c:2020
Please submit a full bug report,
It needs both -O and -fPIC to trigger this bug.
I've reduce the code in question to:
int x;
static void ** STACK;
static void get_block () {
while (1)
{
STACK[0] = (void *)(&x+(1L<<48));
}
}
Which gives me this error:
$ gcc -O -fPIC test5.i -c -o test.o
test5.i: In function 'get_block':
test5.i:9: error: unrecognizable insn:
(insn 38 37 33 0 (set (reg/f:DI 58 [ D.1466 ])

(nil))))
test5.i:9: internal compiler error: in extract_insn, at recog.c:2020
gcc-3.4 3.4.5-1 gives the same error, gcc-4.1 4.1-0exp6
seems to compile this without problems.
