ASM Statements

#asm, #endasm

_ _asm

FUNCTION

(a) #asm - #endasm

•

The assembler source program described by the user can be embedded in an assembler source file to be

output by this C compiler by using the preprocessing directives #asm and #endasm.

•

#asm and #endasm lines will not be output.

(b) _ _asm

•

An assembly instruction is output and inserted in an assembler source by describing an assembly code for

a character string literal.

EFFECT

•

Global variables of the C source can be manipulated in the assembler source

•

Functions that cannot be described in the C source can be implemented

•

The assembler source output by the C compiler can be manually optimized and embeded it in the C source

(to obtain efficient objects)

USAGE

(a) #asm - #endasm

•

Indicate the start of the assembler source with the #asm directive and the end of the assembler source

with the #endasm directive. Describe the assembler source between #asm and #endasm.
