Macro on the same line as a label

[sinsi]

Just spent a bit of time tracking down a problem (masm bug?)

Code Select Expand

start:  mov esi,rv(GetModuleHandle,0) is assembled as

Code Select Expand

       mov esi.eaxmissing the call to GetModuleHandle altogether.
Without the start: label it assembles correctly.

Is it a bug or am I missing something?

It's by design :P

This concerns only macros that return something, i.e. functions. The same problem occurs e.g. with

Code Select Expand

.if eax
.elseif rv(GetModuleHandle,0)!=400000h
.else
.endif


Note that UAsm behaves exactly like MASM. AsmC, in contrast, produces a different result and is thus not MASM-compatible.

Jeez, thought I would start using some macros and then this happens. Is it documented anywhere?

Correct? It's "by design", meaning that Micros??t will not hold your hot little hand etc etc - you know the story ;)
