Since 97d6161f6a7fa712 / r11-7370 "libstdc++: More efficient
days from date" I see an additional 81 testsuite-errors for
cris-elf, with this in g++.log for one randomly picked
regressing test:
FAIL: g++.dg/cpp1y/pr57640.C -std=c++2a (test for excess errors)
Excess errors:
/x/gccobj/cris-elf/libstdc++-v3/include/chrono:2483:25: error: invalid
'static_cast' from type 'const std::chrono::month' to type 'uint32_t' {aka
'long unsigned int'}
/x/gccobj/cris-elf/libstdc++-v3/include/chrono:2484:25: error: invalid
'static_cast' from type 'const std::chrono::day' to type 'uint32_t' {aka 'long
unsigned int'}
/x/gccobj/cris-elf/libstdc++-v3/include/chrono:2496:69: error: no matching
function for call to 'std::chrono::duration<long long int, std::ratio<86400>
>::duration(<brace-enclosed initializer list>)'
The commit shows conversions to uint32_t, which for
e.g. x86_64-linux is "unsigned int", and there are explicit
conversions to unsigned int for month and day (see patch
context).
But, "newlib ILP32 targets" have an uint32_t that is
effectively typedef'd "long unsigned int" (see
newlib-stdint.h UINT32_TYPE).
Better provide an unsigned long conversion aside the
unsigned ones.
Tested cris-elf. Pending x86_64-linux regtest results, ok?
libstdc++-v3:
PR libstdc++/99301
* include/std/chrono (day, month): Provide
conversion to unsigned long.
