Here is is ICE message:
$ m6811-elf-gcc -c -m68hc12 -O3 -fomit-frame-pointer strcat.c
strcat.c: In function `strcat':
strcat.c:18: internal compiler error: in verify_local_live_at_start, at flow.c:546
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
Environment:
System: Linux namsh 2.6.4 #66 Thu Mar 11 22:55:35 KST 2004 i686 athlon i386 GNU/Linux
Architecture: i686
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: m6811-unknown-none
configured with: ../configure --disable-nls --target=m6811-elf --prefix=/usr/GNUHCS --program-prefix=m6811-elf- --with-gnu-ld --with-gnu-as --disable-shared --enable-languages=c,c++ --without-headers --with-newlib
How-To-Repeat:
Here is a source:
/* strcat.c */
char *strcat(char *d, const char *s)
{
char *p = d;
while (*d) d++;
while ((*d = *s) != '\0') { d++; s++; }
return p;
}
------- Additional Comments From namsh at kldp dot org 2004-03-12 01:56 -------
Fix:
1. Do not use '-fomit-frame-pointer'
2. Use '-O2' instead of '-O3'.

I suspect this is related to the -fweb that was activated when -O3
(disabled completely in m6811 in 3.4). Going to check.
