Slightly more reduced:
void stpi_unpack_16_1(int length, unsigned char *out, unsigned char bit)
{
unsigned char tempin;
unsigned char temp[16];
for (bit = 128; length > 0; length--) {
if (tempin & 128)
temp[0] |= bit;
else
{
*out++ = temp[1];
*out++ = temp[2];
*out++ = temp[3];
*out++ = temp[4];
*out++ = temp[5];
*out++ = temp[6];
*out++ = temp[7];
*out++ = temp[9];
*out++ = temp[10];
*out++ = temp[11];
*out++ = temp[12];
*out++ = temp[13];
*out++ = temp[14];
*out++ = temp[15];
__builtin_memset (temp, 0, 16);
}
}
}
it ICEs on
/* We track only variables whose size is <= MAX_VAR_PARTS bytes
thus there are at most MAX_VAR_PARTS different offsets. */
gcc_assert (var->n_var_parts < MAX_VAR_PARTS);
because var->n_var_parts is == MAX_VAR_PARTS. It looks like the analysis
part is wrong in trying to track temp[].
