Data Fields

tree decl

Detailed Description

   Structure used to describe the attributes of a REG in similar way as
   mem_attrs does for MEM above.  Note that the OFFSET field is calculated
   in the same way as for mem_attrs, rather than in the same way as a
   SUBREG_BYTE.  For example, if a big-endian target stores a byte
   object in the low part of a 4-byte register, the OFFSET field
   will be -3 rather than 0.
