Hello,
I am trying to explore loop distribution. The following sample code
has been constructed according to the example given in
tree-loop-distribution.c file.
int main()
{
int i, j, a[100], b, c;
for (i=0; i<100; i++)
{
a[i] = b + 5;
c = a[i-1] + 10;
}
printf ("%d, %d\n", a[20], b, c);
return 0;
}
I use the following cmd line to compile the code :
install/bin/gcc -fdump-tree-all -O3 -ftree-loop-distribution filename.c
However, in the dump file *.ldist, there is no loop distribution
visible. Does this indicate that loop distribution is not performed?
Or is there some other option that I need to pass to enable this pass?
Any pointers in this regard would be highly appreciated!
