The paper P2614R2 was approved in Issaquah, 2023. It deprecates the
float_denorm_style enumeration type, its enumerators, and the
numeric_limits::has_denorm and numeric_limits::has_denorm_loss static
data members.
I don't understand why the std/ranges/iota/max_size_type.cc test doesn't
get warnings for using numeric_limits::has_denorm{,_loss} only for using
the enumerator.
libstdc++-v3/ChangeLog:
* doc/xml/manual/evolution.xml: Document deprecations.
* doc/html/manual/api.html: Regenerate.
* include/bits/max_size_type.h (numeric_limits::has_denorm):
Mark as deprecated.
(numeric_limits::has_denorm_loss): Likewise.
* include/std/limits (float_denorm_style): Mark as deprecated.
(numeric_limits::has_denorm, numeric_limits::has_denorm_loss):
Mark as deprecated.
* testsuite/18_support/numeric_limits/char16_32_t.cc: Add
dg-warning for expected deprecation warnings.
* testsuite/18_support/numeric_limits/char8_t.cc: Likewise.
* testsuite/18_support/numeric_limits/denorm_min.cc: Likewise.
* testsuite/18_support/numeric_limits/dr559.cc: Likewise.
* testsuite/18_support/numeric_limits/requirements/constexpr_data.cc:
Likewise.
* testsuite/18_support/numeric_limits/specialization_default_values.cc:
Likewise.
* testsuite/std/ranges/iota/max_size_type.cc: Likewise.
