Nathan Sidwell 4b5f564a5d libcpp: Provide date routine ... Joseph pointed me at cb_get_source_date_epoch, which allows repeatable builds and solves a FIXME I had on the modules branch. Unfortunately it's used exclusively to generate __DATE__ and __TIME__ values, which fallback to using a time(2) call. It'd be nicer if the preprocessor made whatever time value it determined available to the rest of the compiler. So this patch adds a new cpp_get_date function, which abstracts the call to the get_source_date_epoch hook, or uses time directly. The value is cached. Thus the timestamp I end up putting on CMI files matches __DATE__ and __TIME__ expansions. That seems worthwhile. libcpp/ * include/cpplib.h (enum class CPP_time_kind): New. (cpp_get_date): Declare. * internal.h (struct cpp_reader): Replace source_date_epoch with time_stamp and time_stamp_kind. * init.c (cpp_create_reader): Initialize them. * macro.c (_cpp_builtin_macro_text): Use cpp_get_date. (cpp_get_date): Broken out from _cpp_builtin_macro_text and genericized.		2020-11-06 08:59:20 -08:00
