A great week for people who like to keep their bit widths in check.
- ByteAddressBuffer gets new methods to work with 16, 32 and 64-bit values.
- 16-bit ints means you can replace both int and float min* types explicitly now.
- New types with specific bit widths: (u)int16_t, (u)int32_t, float16_t, float32_t and float64_t.
- (u)int64_t has been around for a while ago.
- Lots of SPIR-V work, of course, including viewport index support.
- /od is now one of the /o[0-3] group. Whether debug information is produced or not depends on /Zi anyway; this really is just about how many optimizations to perform.
