this bug is related to casting the built-in strlen() function to a signed or
unsigned char where the pointer is on the stack.
This is the correct code generated....
signed char *cp;
signed int size;
size = strlen(cp);
mov 14(r1), r10 ; cp, size
dec r10 ; size
.L__strlenhi__480:
inc r10 ; size
tst.b 0(r10) ; size
jne .L__strlenhi__480
sub 14(r1), r10 ; cp, size
This is what you get with a signed char as destination...
signed char *cp;
signed char size;
size = strlen(cp);
mov 14(r1), r15 ; cp
dec r15
.L__strlenhi__483:
inc r15
tst.b 0(r15)
jne .L__strlenhi__483
mov.b r15, r11 ; size
sub.b 14(r1), r11 ; cp, size
the buffer is at address 1d7a and the buffer has one char in it.
0x7b - 0x1d = 94 !!
The difference between them is a length of 94 & 2 (in my case)
