I triggered a segfault on a i386 target with a piece of code intented to be
compiled for avr target. I get a more descriptive message by modifiying the code
a little bit. Here is the source, messages and versions :
typedef unsigned long uint32_t;
typedef unsigned char uint8_t;
int
main (void)
{
volatile uint32_t d = 0;
volatile uint8_t b0 = 1, b1 = 2, b2 = 3, b3 = 4;
asm ("mov %C0, %3" "\r\n"
"mov %D0, %4" "\r\n"
: "=d" (d) : "r" (b0), "r" (b1), "r" (b2), "r" (b3));
return 0;
}
/*
cc -g -Wall -W -Wundef -O2 -I../../.. -I../../../common -MMD -include
avrconfig.h t.c -o t
t.c: In function `main':
t.c:13: internal compiler error: Segmentation fault
*/
/* Or with a modified version :
typedef unsigned long uint32_t;
typedef unsigned char uint8_t;
int
main (void)
{
volatile uint32_t d = 0;
volatile uint8_t b0 = 1, b1 = 2, b2 = 3, b3 = 4;
asm ("mov %D0, %4" "\r\n"
: "=d" (d) : "r" (b0), "r" (b1), "r" (b2), "r" (b3));
return 0;
}

I forgot to mention, the patch was against the mainline, sources current as of
July 20th.

------- Comment #4 from pinskia at gcc dot gnu dot org 2009-01-01 21:12 -------
The segfault has been changed into an error with PR 13506 but that does not
mean with RTL checking turned on.
In fact with RTL checking we get:
t.c: In function 'main':
t.c:13: internal compiler error: RTL check: expected elt 0 type 'e' or 'u',
have 'i' (rtx reg) in print_operand, at config/i386/i386.c:9010
Please submit a full bug report,
with preprocessed source if appropriate.

Michael, could you ping your patch?
