The if-conversion is done twice , the first before reload and second
after it. The fisrt time it is not activated since the register allocator
does not supports predicated instructions. We are working to do
modulo-scheduling for loops, for this we need to activate the first
call .How can this be done??
regards,
Ritu.

First update regalloc and other passes to support predicated execution
(this is nontrivial to do) and then you can enable it. There is no way
around.

Look at the uses of reload_completed, and change the ones that need to be
changed.
