Fix initial stack pointer alignment for x86_64 in crt0.s startup code of bootstrap. SysV ABI states that upon function entry (rsp + 8) % 16 = 0. There, we have to align the stack to 16 bytes before all 'call' instruction not 8. Otherwise FPU (GP) exception might be raised later on because of unaligned FPU accesses. issue #3365 |
