a2789d611f * fix crash in debug output in TX86AsmOptimizer.DoArithCombineOpt for DEC/INC $reg 2022-11-07 23:35:23 +01:00

dbd8259c48 * x86: Fixed mistake in var9 optimisation under -Os; "andl $255,%eax" is not 
smaller than "movzbl %al,%eax" because the immediate is sign-extended,
	not zero-extended, so $255 will be stored as a 32-bit value.
