#18 #if ( ... ) fails

[Wasilios Goutas]

Hello Eckard,

I have code like this which breaks te parser

int test(void){
#if ( TEST == 1 )
  return 1;
#elif  ( TEST == 2 )
  return 2;
#else
#error unexpected 
#endif
}

I'm not sure if this is C99 conform but the ARM compiler is handling it.

Hello Wasili.

I have tested your examples with the newest Moritz patch published on 2020-12-23 together with the patch I have provided to solve your issue struct initializer with condition

• But I was not able to reproduce your issue.
• I don't want to add the complete XML output here but as far as I can see every path of your compiler-switch is present including the error-directive.

The Nassi Shneiderman diagram for it looks like this:

test ( ) int test ( ) PREPROSESSOR ALTERNATIVES PREPROSESSOR DEFAULTS #if ( TEST == 1 ) return 1 #elif ( TEST == 2 ) return 2 #else #error unexpected

(Note: Here in the Forum the HTML result looks a little bit different. But you see that all your code-parts are present )

I wish you a happy new year.

Stay healthy,
Eckard.
