https://issues.dlang.org/show_bug.cgi?id=2617 --- Comment #5 from Walter Bright <bugzilla@digitalmars.com> --- The following code: uint func() { asm { naked; inc [EAX]; inc byte ptr [EAX]; inc short ptr [EAX]; inc int ptr [EAX]; inc long ptr [EAX]; } } generates: __D5test24funcFZk: inc byte ptr [EAX] inc byte ptr [EAX] inc word ptr [EAX] inc dword ptr [EAX] inc byte ptr [EAX] <== !!!!! That last is certainly a problem; it should be rejected by the compiler. As for the first instruction, I'm concerned about changing the behavior. Messing with people's existing, working asm code is risky. -- |

https://issues.dlang.org/show_bug.cgi?id=2617 --- Comment #6 from Vladimir Panteleev <dlang-bugzilla@thecybershadow.net> --- (In reply to Walter Bright from comment #5) > As for the first instruction, I'm concerned about changing the behavior. Messing with people's existing, working asm code is risky. See issue 7388. The problem is that if you copy/paste code from another program, you'll get a different result. It probably should be deprecated, forcing users to explicitly specify the operand size. -- |

https://issues.dlang.org/show_bug.cgi?id=2617 --- Comment #8 from Walter Bright <bugzilla@digitalmars.com> --- Looking at my ancient Intel 8088 manual, it says: INC [BX] is ambiguous and so must use BYTE PTR or WORD PTR. Since the behavior of iasm is modeled after Intel's syntax, that pretty much settles it. -- |
