#pragma inline_asm
Description Format: #pragma inline_asm (<function name>[,...])
Description:
Example:
Remarks:
<function name>: Do not specify a C++ member function or an overloaded
function.
Performs inline expansion for the functions written in assembly language
declared by #pragma inline_asm.
Parameters of a function that is written in assembly language are referenced
in an inline_asm function because they are stacked or stored in registers in
the same way as general function calls. The return value of an inline
function written in assembly language should be set to (E)R0.
#pragma inline_asm(shlu)
extern unsigned int x;
static unsigned int shlu(unsigned int a)

void main(void)

1. Compile the program using the object-type specification option

treated as the target functions.
External definition will be generated for functions specified by #pragma
inline_asm. When a source program includes the same inline function
description, be sure to specify static before the function declaration.
If static is specified, an external definition will not be created.
