Syntax

-s-

Description

C code requires a small startup file containing system initialization code to be executed before entering main. The standard startup code is found in the object file $(InstallDir)/lib/crt0.hzo and the compiler driver automatically links this into your program. If, however, you do not require the standard startup code because you have a pure assembly language application, you can request the compiler driver to exclude this standard startup code from the link using the -s- option.

You will find the source code for the standard startup module crt0 in the file $(InstallDir)/src/crt0.asm.

Setting this in CrossStudio

To exclude the standard startup code for a project:

Example

To instruct the compiler to assemble file1.asm and file2.asm into app.hzx and not link the standard startup code:

hcl file1.asm file2.asm -s- -o app.hzx
