[Andrew, since you suggested this, is this what you had in mind?]. The equal_p method in vrange_storage is only used to compare ranges that are the same type. No sense passing the type if it can be determined from the range being compared.
gcc/ChangeLog: * gimple-range-cache.cc (sbr_sparse_bitmap::set_bb_range): Do not pass type to vrange_storage::equal_p. * value-range-storage.cc (vrange_storage::equal_p): Remove type. (irange_storage::equal_p): Same. (frange_storage::equal_p): Same. * value-range-storage.h (class frange_storage): Same. --- gcc/gimple-range-cache.cc | 2 +- gcc/value-range-storage.cc | 28 +++++++++++----------------- gcc/value-range-storage.h | 6 +++--- 3 files changed, 15 insertions(+), 21 deletions(-) diff --git a/gcc/gimple-range-cache.cc b/gcc/gimple-range-cache.cc index 92622fc5000..07c69ef858a 100644 --- a/gcc/gimple-range-cache.cc +++ b/gcc/gimple-range-cache.cc @@ -320,7 +320,7 @@ sbr_sparse_bitmap::set_bb_range (const_basic_block bb, const vrange &r) // Loop thru the values to see if R is already present. for (int x = 0; x < SBR_NUM; x++) - if (!m_range[x] || m_range[x]->equal_p (r, m_type)) + if (!m_range[x] || m_range[x]->equal_p (r)) { if (!m_range[x]) m_range[x] = m_range_allocator->clone (r); diff --git a/gcc/value-range-storage.cc b/gcc/value-range-storage.cc index 7d2de5e8384..1e06a7acc8d 100644 --- a/gcc/value-range-storage.cc +++ b/gcc/value-range-storage.cc @@ -206,20 +206,22 @@ vrange_storage::fits_p (const vrange &r) const return false; } -// Return TRUE if the range in storage is equal to R. +// Return TRUE if the range in storage is equal to R.
