timing your functions

hi everyone. If you have a function created in your code and you want to find out how long it takes for it to run you can use a struct called gettimeofday(). so lets say we have a function like this int myfunction (int r) { /*some math calculations*/ return answer; } How do i set up...

Help with __builtin_prefetch function and it's timing

Hello there, I just needed to know how to get the timing right when using the gcc __builtin_prefetch() function, that is, how many instructions before the actual utilization of the data should I make the prefetch call. I will be measuring the L1 cache hit rate with valgrind's cachegrind,...

Weird timing results in C

I was running some timings in my code to see which of several functions was the best and I've been getting some odd results. Here's the code I'm using: static double time_loop(int (*foo)(int)) { clock_t start, end; int n = 0, i = 0; start = clock(); for (; i <= MAXN; i++) if...

Byte swap timing

I have noticed the difference in byte swap timing between two Ubuntu systems. The bswap_32 used to work just fine on the old system, but on the new one it lags behind home-grown swap. My code: #include <stdio.h> #include <stdlib.h> #include <string.h> #include <byteswap.h> #include...

sigreturn

SIGRETURN(2)						      BSD System Calls Manual						      SIGRETURN(2)

NAME

     sigreturn -- return from signal

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <signal.h>

     int
     sigreturn(const ucontext_t *scp);

DESCRIPTION

     The sigreturn() system call allows users to atomically unmask, switch stacks, and return from a signal context.  The thread's signal mask and
     stack status are restored from the context structure pointed to by scp.  The system call does not return; the users stack pointer, frame
     pointer, argument pointer, and processor status longword are restored from the context.  Execution resumes at the specified pc.  This system
     call is used by the trampoline code and longjmp(3) when returning from a signal to the previously executing program.

RETURN VALUES

     If successful, the system call does not return.  Otherwise, a value of -1 is returned and errno is set to indicate the error.

ERRORS

     The sigreturn() system call will fail and the thread context will remain unchanged if one of the following occurs.

     [EFAULT]		The scp argument points to memory that is not a valid part of the process address space.

     [EINVAL]		The process status longword is invalid or would improperly raise the privilege level of the process.

SEE ALSO

     sigaction(2), setjmp(3), ucontext(3)

HISTORY

     The sigreturn() system call appeared in 4.3BSD.
