Subject: How do we access higher order bits of a register?
Date: Tue, 22 Nov 2011 15:31:00 -0000	[thread overview]
Message-ID: <CA+V5N8mtZKboyCyFeuxD4gH_byTUus=50hxqKA0NMxrKgq2gdA@mail.gmail.com> (raw)

Hi,

I wanted to write an RTL that would access the higher order bits of a
register.  I saw that high:<mode> works only with constants or labels.
 The subreg:<mode> only takes the lower order bits.  Can't find any
way to address the higher order bits.  Any help would be appreciated.

Thanks and regards
Ayonam
