Sajeesh.K.K,
Because the ideqval opcode not support bitwiseand nest in it, so vfrcompiler
reports this error. You can use the following expression to meet your request:
suppressif (get(NVData.mybitmap) & 0x1) == 0x0;
Thanks,
Eric

Subject: [edk2] Bitwise and operator in VFR file
Hello All,
I have a question regarding the use of bitwiseand operator in suppressif
statement.
Basically i have a bitmap in the NVConfig structure. I need to selectively
suppress some of the options to the user based on this bitmap.
I have something similar to this.
"suppressif ideqval NVData.mybitmap & 0x1 == 0x0;".
Is it legal to use BitWiseAnd ("&") operator inside suppressif statement ??
The list file generated the vfrcompiler looks something like this:
suppressif ideqval NVData.mybitmap & 0x1 == 0x0;
>000004A9: 0A 82 ===> suppressif opcode
>000004AB: 45 8A 01 00 00 00 00 00 00 00 ===> push 64bit unsigned integer
>000004B5: 45 0A 00 00 00 00 00 00 00 00 ===> push 64bit unsigned integer
>000004BF: 2F 02 ===> push TRUE if two
>expressions are equal
>000004C1: 35 02 ===> Bitwise AND two
>unsigned integers and push the result.
>000004C3: 29 02 ===> Marks the end of
>scope.
I am getting "unrecognised token : &" from vfrcompiler during compilation, even
if the opcode to perform bitwise and operation is generated.
Please let me know how to get around this.
Thanks,
Sajeesh.K.K
