--- Comment #8 from Martin Liška <marxin at gcc dot gnu.org> ---
All right, I vanished the test-case:
$ cat 1.i
inline __attribute__((__always_inline__)) __attribute__((gnu_inline)) void *
memcpy();
void *apply_relocate_add_write = memcpy;
$ touch 2.s
$ cat 3.i
enum { false, true } * __memcpy();
_Bool kasan_check_range();
void *memcpy(void *dest, void *src, long len) {
if (kasan_check_range(len, false, 0) || kasan_check_range(len, true, 0))
return __memcpy(dest, src, len);
}
long LZ4_decompress_generic_dst_restSize;
char LZ4_decompress_generic_dst_lowPrefix;
void LZ4_decompress_generic_dst() {
__builtin_memcpy(LZ4_decompress_generic_dst,
&LZ4_decompress_generic_dst_lowPrefix,
LZ4_decompress_generic_dst_restSize);
}
