卜部昌平	64ec438b5b	internal/bits.h rework ... Improving readability by converting some macros into inline functions. Also improved support for recent x86_64 processors, which have better instructions for the purposes.	2019-12-26 20:45:12 +09:00
卜部昌平	0958e19ffb	add several __has_something macro ... With these macros implemented we can write codes just like we can assume the compiler being clang. MSC_VERSION_SINCE is defined to implement those macros, but turned out to be handy for other places. The -fdeclspec compiler flag is necessary for clang to properly handle __has_declspec().	2019-12-26 20:45:12 +09:00
卜部昌平	b739a63eb4	split internal.h into files ... One day, I could not resist the way it was written. I finally started to make the code clean. This changeset is the beginning of a series of housekeeping commits. It is a simple refactoring; split internal.h into files, so that we can divide and concur in the upcoming commits. No lines of codes are either added or removed, except the obvious file headers/footers. The generated binary is identical to the one before.	2019-12-26 20:45:12 +09:00
