Add flag -ftree-loop-if-convert-stores. This patch adds a flag that controls the replacement of the memory writes that are in predicated basic blocks with a full write: for (...) if (cond) A[i] = foo is replaced with: for (...) A[i] = cond ? foo : A[i] In order to do this, we have to call gimple_could_trap_p instead of gimple_assign_rhs_could_trap_p, as we have to also check that the LHS of assign stmts does not trap. * common.opt (ftree-loop-if-convert-stores): New flag. * doc/invoke.texi (ftree-loop-if-convert-stores): Documented. * tree-if-conv.c (ifc_temp_var): Pass an extra parameter GSI.
