C51: OPTIMIZED C WITH INLINE ASSEMBLER


Information in this article applies to:

  • C51 Version 4 and Earlier

QUESTION

I'm using inline assembly in my C program, and the code won't optimize, no matter what I do. What's going on?

ANSWER

In order to use inline assembly, you must include #pragma src in the C source file. This overrides the optimizer and generates unoptimized assembly instructions from your C code.

A better way to use assembly in conjunction with C may be found by referring to C51: CALLING ASSEMBLY ROUTINES FROM C in the database.
