Ian Lance Taylor	284f02bba8	Tue Jun 9 12:20:05 1998 Alan Modra <alan@spri.levels.unisa.edu.au> * config/tc-i386.h: Change Data16 to Size16, Data32 to Size32, IgnoreDataSize to IgnoreSize as they are used for address size as well as data size. * config/tc-i386.c: Likewise. Add code to reject addr32/data32 in 32-bit mode, similarly addr16/data16 and variants.	29 years ago
