Use GCC to output assembly list files with C source code annotations

 

We all know that the GCC-s switch can be used to generate assembly code,

However, sometimes, it is not enough to have a single assembly file. We hope that the source code of the C language program and the assembly language text will be checked together,

This is the listing function. No special FAQ is provided in GCC,

I have checked a lot of information on the Internet to find out how to implement it.

 

Gcc-C-g-wa,-adlhn ee. c> ee. Anno. s

 

The resulting ee. Anno. S is the list of C and Assembly hybrid sorting corresponding to ee. C.

 

Another example is the C program.

 

/* EE */

# Include <stdio. h>

# Include <stdio. h>

# Include <string. h>

# Include <stdlib. h>

# Include <windows. h>

Int main (INT argc, char ** argv)

{

Char * P = "to stdout ";

Int Ic = (INT) getstdhandle (std_output_handle );

Printf ("% d/N", IC );

Writefile (IC, P, strlen (P), & IC, null );

 

Return 0;

}
