[PATCH] D137572: [AVR][Clang] Implement __AVR_HAVE_*__ macros

[Ayke via Phabricator via cfe-commits]

aykevl updated this revision to Diff 475419.
aykevl added a comment.

- Fix ArchHas3BytePC to remove arch 107 (of which no chips have more than 128kB flash)
- Fix ArchHasELPM/ArchHasELPMX to add arch 102 (it does support elpm even though avr-gcc claims it doesn't).
- Add notes where the provided macros may not be correct in all cases. It's still better than avr-gcc though.
