Add `dontthrow` attribute to most libc functions This will help C++ code that uses exceptions to be tinier. For example, this change shaves away 1000 lines of assembly code from LLVM's libcxx, which is 0.7% of all assembly instructions in the entire library. 2024-01-09 09:26:03 +00:00			`long syscall(long, ...) libcesque;`
