At no point in all this does anyone care in the slightest about the speed of your little toys or of the cute little tcc.  tcc might be ideal for the half-dozen people in the world who think C scripts are a good idea, and it had its place in a time when "live Linux" systems were booted from floppies, but that's about it.

  I don't think that's an option with tcc.

It's not listed in the tcc help anyway.

gcc works by generating intermediate assembly anyway, and the -S option exposes it.
 Generally it depends on compiler. Mine has it for example.

Cool.
If you don't mind, what assembly code does your compiler generate for this C code:
-------------------------------------------------
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char *argv[]) {
     int N=0;
     int *nums = malloc(2 * sizeof(int));
     FILE* datafile = fopen(argv[1], "r");
     while(fscanf(datafile, "%d", &nums[N++]) == 1){
         nums = realloc(nums, (N+1) * sizeof(int));
     }
     fclose (datafile);
     N--;
     for(int i=0;i<N;i++) {
         printf("%d.%d  ", i+1, nums[i]);
     }
     free(nums);
     printf("\n");
     return 0;
}
