[Vm-dev] NoDbgRegParms test case results

[gettimothy]

Hi all.




I implemented a simple test case to test my theory that my platform does not support the regparms(0) function attribute and my theory is bunk. bleah.


I modified this autotools tutorial's source files at 


http://www.gnu.org/software/automake/manual/html_node/Creating-amhello.html



to mimic the __attribute__((regparms(0))) behavior in cog.


I could not recreate the error under any compination of PRODUCTION and #if #else conditions.
I am at a loss at the moment (and sick with a cold) so I will have to revisit this later.
CMakeVMMakerSqueak dev is blocked by this issue.




I added a test.h file to the src directory that looks like this:





 bash-4.2$ cat test.h 
#undef NoDbgRegParms
#define PRODUCTION 1
#if !PRODUCTION && defined(__GNUC__) && !defined(NoDbgRegParms)
# define NoDbgRegParms __attribute__ ((regparm(0)))
#else
# define NoDbgRegParms __attribute__ ((deprecated))
#endif

int plus (int a, int b) NoDbgRegParms;

and modified the main.c .
bash-4.2$ cat src/main.c
#include <config.h> 
#include <stdio.h>
#include "test.h"

int main(void){
 int p;

 puts("Hello World!");
 puts ("This is " PACKAGE_STRING ".");

 p=plus(3,3);

 printf("%d\n",p);
 return 0;
}

int plus (int a, int b) {
 return a + b;
}
