++;; peephole2 optimization will be done only if fint and if-then-else
++;; are dependent.added condition for the same.
++;; if they are dependent then gcc is giving "flow control insn inside a basic block"
++;; testcase:
++;; volatile float vec = 1.0;
++;; volatile int ci = 2;
++;; register int cj = (int)(vec);
++;;// ci=cj;
++;;// if (ci <0) {
++;; if (cj < 0) {
++;; ci = 0;
++;; }
++;; commenting for now.we will check the possibility of this optimization later
