Not getting the concept

I looked at the TRKADDR macro and found that it does different expansions based on SYSSTATE AMODE64. The author evidently thought that using all 64 bits of registers was disallowed unless AMODE64 was set; and conversely, also seemed to think that it's required that *G instructions be used if on

Re: Not getting the concept

That's plausible. I don't know how old TRKADDR is, but the non-G expansions would work on ESA. On Wed, Sep 30, 2015 at 10:26 AM, Paul Gilmartin < 0014e0e4a59b-dmarc-requ...@listserv.uga.edu> wrote: > On 2015-09-30, at 08:10, Steve Smith wrote: > > > I looked at the TRKADDR macro and found
