RE: [sdcc-devel]Using movc to read xram

[Dario V. <dve...@el...>]

It is an interesting feature but needs more flexibility.
With a command line option you force all your code to work in same way.

Maybe should be better a #pragma directive that let you select where
use movc istead of movx.

Suppose you have a layout memory like Paul's board but you also have
some hardware latch driven by RD pin: you would use movx to access it
and cannot if the global options force the use of movc.

Commercial compilers also use the "code" storage class for variables.

eg. code int my_var;
