Richard Smith	84c6b3d293	PR5683: Issue a warning when subtracting pointers to types of zero size, and treat such subtractions as being non-constant. Patch by Serge Pavlov! With a few tweaks by me. llvm-svn: 190439	2013-09-10 21:34:14 +00:00
Serge Pavlov	f7c1a2152a	Clean up empty struct/union recognition. Make use of getTypeSizeInChars to detect structs/unions of zero size. It allows more accurate detection of types of zero size. It however has a side effect - sequence of used types may change, that is why the test 'override-layout' was modified. llvm-svn: 184088	2013-06-17 17:18:51 +00:00

Clean up empty struct/union recognition.

Make use of getTypeSizeInChars to detect structs/unions of zero size. It allows
more accurate detection of types of zero size. It however has a side effect -
sequence of used types may change, that is why the test 'override-layout' was
modified.
