Subject: Help required on rda [FRV]
Date: Wed, 06 Apr 2005 10:58:00 -0000	[thread overview]
Message-ID: <> (raw)

Dear Jimb,
 I Appreciate your contribution to redhat on rda,i have problem using
rda compilied for FRV target,while debugging thread application using
rda and gdb compilied for FRV,there is a delay in thread creation when
compared to creation of thread running the prog on console.
 Can u pls guide me in solving this problem

Thread program used:thread.c

#include <stdio.h>
#include <pthread.h>
#include <sys/time.h>
#include <assert.h>

long initial_start_time;
long initial_end_time;

void *do_nothing(void *arg)
 struct timeval t;
 struct timezone tz;

 gettimeofday(&t, &tz);
printf("%d: Hello World!\n", arg);
   return NULL;

#define NUM_THREADS 1
int main(void)
   int i;
   pthread_t tid[NUM_THREADS];

 struct timeval t_start;
 struct timezone tz_start;

 struct timeval t_end;
 struct timezone tz_end;
 gettimeofday(&t_start, &tz_start);
  printf("Start  time %llu\n", t_start.tv_sec);
 initial_start_time = t_start.tv_sec;

   for (i = 0; i < NUM_THREADS; i++)
       printf("Creating thread %d\n", i);
   pthread_create(&tid[i], NULL, do_nothing, NULL);

   for(i =  0; i < NUM_THREADS; i++)
     pthread_join(tid[i], NULL);
 gettimeofday(&t_end, &tz_start);
  printf("End  time %llu\n", t_end.tv_sec);
 initial_end_time = t_end.tv_sec;

   return 0;
