This is the same as `unreachable` except it always traps violations,
even if we're not running in MODE=dbg. This is useful for impossible
conditions relating to system calls. It avoids terrifying bugs where
control falls through to an unrelated function.
You can now use the hardest fastest and most dangerous language there is
with Cosmopolitan. So far about 75% of LLVM libcxx has been added. A few
breaking changes needed to be made to help this go smoothly.
- Rename nothrow to dontthrow
- Rename nodiscard to dontdiscard
- Add some libm functions, e.g. lgamma, nan, etc.
- Change intmax_t from int128 to int64 like everything else
- Introduce %jjd formatting directive for int128_t
- Introduce strtoi128(), strtou128(), etc.
- Rename bsrmax() to bsr128()
Some of the templates that should be working currently are std::vector,
std::string, std::map, std::set, std::deque, etc.
Compilers like GCC require comments on lines like `#endif rdmsr`. Since
the rdmsr macro was only being used in arch_prctl(), I've localized the
macro, and I'm considering deleting arch_prctl() too, since there isn't
any way to have mem segments unfortunately across operating systems ;_;
The remaining changed lines are due to clang-format which runs on auto.
