Even though ranger is type agnostic, SCEV seems to only work with integers. This patch removes some FIXME notes making it explicit that bounds_of_var_in_loop only works with iranges.
Tested on x86-64 Linux. gcc/ChangeLog: * gimple-range-fold.cc (fold_using_range::range_of_phi): Only query SCEV for integers. (fold_using_range::range_of_ssa_name_with_loop_info): Remove irange check. --- gcc/gimple-range-fold.cc | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/gcc/gimple-range-fold.cc b/gcc/gimple-range-fold.cc index 6f907df5bf5..7665c954f2b 100644 --- a/gcc/gimple-range-fold.cc +++ b/gcc/gimple-range-fold.cc @@ -853,12 +853,14 @@ fold_using_range::range_of_phi (vrange &r, gphi *phi, fur_source &src) } // If SCEV is available, query if this PHI has any knonwn values. - if (scev_initialized_p () && !POINTER_TYPE_P (TREE_TYPE (phi_def))) + if (scev_initialized_p () + && !POINTER_TYPE_P (TREE_TYPE (phi_def)) + && irange::supports_p (TREE_TYPE (phi_def))) { - value_range loop_range; class loop *l = loop_containing_stmt (phi); if (l && loop_outer (l)) { + int_range_max loop_range; range_of_ssa_name_with_loop_info (loop_range, phi_def, l, phi, src); if (!loop_range.varying_p ()) { @@ -1337,9 +1339,7 @@ fold_using_range::range_of_ssa_name_with_loop_info (irange &r, tree name, { gcc_checking_assert (TREE_CODE (name) == SSA_NAME); tree min, max, type = TREE_TYPE (name); - // FIXME: Remove the supports_p() once all this can handle floats, etc. - if (irange::supports_p (type) - && bounds_of_var_in_loop (&min, &max, src.query (), l, phi, name)) + if (bounds_of_var_in_loop (&min, &max, src.query (), l, phi, name)) { if (TREE_CODE (min) != INTEGER_CST) { -- 2.37.1
