Package: gcc-3.4
Version: 3.4.3-11
Severity: normal
The info file says:
<-- snip -->
With the `-fno-builtin-FUNCTION' option only the built-in function
FUNCTION is disabled. FUNCTION must not begin with `__builtin_'.
If a function is named this is not built-in in this version of
GCC, this option is ignored. There is no corresponding
`-fbuiltin-FUNCTION' option; if you wish to enable built-in
functions selectively when using `-fno-builtin' or
`-ffreestanding', you may define macros such as:
#define abs(n) __builtin_abs ((n))
#define strcpy(d, s) __builtin_strcpy ((d), (s))
<-- snip -->
But:
<-- snip -->
$ cat test.c
#define sprintf __builtin_sprintf
int main()
{
char str[] = "abc";
char buf[10];
sprintf(buf,"%s",str);
return 0;
}
$ gcc-3.4 -S -ffreestanding -Wall test.c
$ cat test.s
.file "test.c"
.section .rodata
.LC0:
.string "abc"
.text
.globl main
.type main, @function

pushl %ebp
movl %esp, %ebp

<-- snip -->
As far as I understand the documentation, the call to strcpy
shouldn't be emitted since this function is not required in a
freestanding environment.
gcc-3.3 and gcc-4.0 behave similar.
I'm not sure whether this is expected, but if it is, the documentation
should be updated.
