# nvc++ defaults to a relaxed, non-IEEE floating-point model that flushes denormals
# to zero and does not honor NaN ordering; -Kieee restores strict IEEE 754 behavior
# (needed for the dtoa/grisu and NaN-comparison code paths).
#
# The following tests are excluded as they trigger known nvc++ 25.5 defects (not
# library bugs); see https://github.com/nlohmann/json for tracking. Only the
# affected language-standard variants are excluded so coverage is otherwise kept:
# - test-comparison_cpp20, test-comparison_legacy_cpp20
# miscompiles cross-type/<=> comparison (e.g. `-17 <= null`)
# - test-constructor1_cpp11
# std::initializer_list lifetime bug -> SIGSEGV
# - test-deserialization_cpp20
# mangles the UTF-8 u8"" string literal in the char8_t (C++20) section
