Realview and old Keil Assembler

Quay Ga

Hi,
I am converting an old code to the Keil-Realview tool.
I have this line, which was fine using the old tool.

__asm{ LDR LR, [LR, #+60] };

The above generate the following error

error: #52: expected a marcro parameter name

Please help

    Hi,

    inline assembler in ARM RealView compiler is not what one wouldt expect anymore. Please look at DUI0205G_rvct_compiler_and_libraries_guide available from ARM. There is a chapter about "Inline and Embedded Assemblers".

    But note: Even if you use the "Embedded Assembler" the result may not be what you need: These statements are arranged like a "function" and are "called", that means jumped at using BL - which of course modifies the LR. I did not find a way to get these __asm functions "inlined" with no extra statements.

    Maybe somebody else can help with this problem.

    With kind regards

    Martin
