$ m6811-elf-gcc -c -m68hc12 -O3 -fomit-frame-pointer  strcat.c

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'.
