C166: Inline Expansion of C Runtime Library Functions

Information in this article applies to:

• C166

QUESTION

The C166 Compiler User's Guide lists intrinsic functions that are expanded inline.

I have noticed that the strcpy function also generates inline code.

Which library functions are expanded inline and is there a way to disable the inline expansion?

ANSWER

The intrinsic library functions (those in intrins.h) are always expanded inline as documented.

Additionally, the following library routines are expanded inline for near function calls:

• strcpy
• strlen
• strchr
• strcmp
• strcat
• memset
• memcpy

There is no way to disable inline expansion. However, you may choose a memory model that uses far function calls and library functions (other than those in intrins.h) that are not expanded inline.
