Confirmed, here is the example which can be reproduced on the clean mainline (I kinda knew which
local patch caused the difference, the BRANCH_COST one so I made this example which breaks):
unsigned int
real_from_integer1 (long long high, int unsigned_p)
{
int i;
if (high < 0)
if (!unsigned_p)
{ i = 1; goto t; }
i = 0;
t:
return i;
}
