Bug in macro code "if var eq 0"?

[Igor]

Am i doing something wrong here:

macro:

Code Select Expand

test_macro macro vr1
if vr1 eq 0
xor ecx, ecx
else
mov rcx, vr1
endif
endm

this code:

Code Select Expand

test_macro FALSE ; 0
test_macro TRUE ; 1
test_macro WS_EX_CLIENTEDGE ; 200h
test_macro WS_EX_CONTROLPARENT ; 10000h
test_macro WS_EX_CLIENTEDGE or WS_EX_CONTROLPARENT ; 10200h
is assembled like this:

Code Select Expand

xor         ecx,ecx
mov         rcx,1
mov         rcx,200h
mov         rcx,10000h
xor         ecx,ecx ; WTF???


He thinks it is equal to zero every time i put "or", how to resolve this?

hi,

this is not a bug. masm replace vr1 by "WS_EX_CLIENTEDGE or WS_EX_CONTROLPARENT" and this is treated as: "if WS_EX_CLIENTEDGE  OR  ( WS_EX_CONTROLPARENT eq 0)".

change "if vr1 eq 0" to  "if (vr1) eq 0"

Ahhh, didn't know that, thank you. It works now.
