Most likely not (If it is then there is something wrong because it is the prologue/epologue
that is removed in this case).

It no longer ICEs one the mainline (20030714) but gcc still produces wrong code.

Confirmed. As of 20030705, neither testcase even compiles:
foo.c: In function `mystrcpy':
foo.c:5: error: Abnormal edges for no purpose in bb 0
foo.c:5: internal compiler error: verify_flow_info failed

I sent the wrong example (here is the right one where it does not sib call in main):
char * mystrcpy(char *dest, char *source)
{
int len = strlen(source);
return memmove(dest, source, len+1);
}
int main()
{
char temp[10];
char *t1="AA";
mystrcpy(temp, t1);
return 0;
}
