Data Fields

tree decl
HOST_WIDE_INT offset

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.
