this might be useful for some of you out
I just upgraded the compiler from version 2.3.0 to
one of the latest nightly snappshots, I think it's 2.3.5. (Windows
I tried to compile some files with the new compiler
that were compiling fine with the older version.
The new compiler went thrue with no errors or
warnings or errors but the program wouldn't run.
After a couple hours I found out that the header
file for special function register and bits caused the problem.
The old compiler did handle the syntax: for example
Sfr P0=0x80 the right way.
The new compiler first reserved Ram space like
P0 .ds 1 and so one for all special function registers and bits, later it
put values to them like mov P0,#0x80.
But P0 has the same address then Ram address 00, P1
the same address then ram address 10h and so on.
As I'm not a compiler designer, maybe someone who
is doing some work on improving the compiler might have a look at this and gives
out some warnings.
I hope this was helpful for some of
Maybe someone can answer me a
Do the nightly snappshots derive from earlier
relised versions or from other snappshots ?
