>From Prakash Prabhu:


#include<stdio.h>
#include<stdlib.h>

void test();
void (*funcPtr)();

int main(int argc, char **argv) {
  funcPtr = test;
  test();
}

void test() {
  if(funcPtr == test) {
    printf("OK!\n");
  } else {
    fprintf(stderr, "Bad!\n");
    exit(1);
  }
}

$ llvm-gcc -emit-llvm -o FPtrEqTest.bc -c FPtrEqTest.c
$ llc -f FPtrEqTest.bc
$ gcc -o FPtrEqTest FPtrEqTest.s
$ ./FPtrEqTest
OK!

$ lli FPtrEqTest.bc
Bad!
