[sdcc-devel] PIC regression tests

[Erik P. <epe...@iv...>]

There are a large number of PIC related bugs in the bug tracker. I am
willing to tackle them, but I don't seem to understand how to run the PIC
specific regression tests. After building and install gputils and gpsim, I
go back to sdcc/src/regression and run make. This results in

../../bin/sdcc -mpic14 -c -pp16f873  b.c
Processor: p16f873
b.c:2:21: p16f873.h: No such file or directory
Temporary ERROR: at the moment you have to use
an include file create by inc2h.pl. See SDCC source:
support/scripts/inc2h.pl
this is a nuisance bug that will be fixed shortly

After some trial and error, I arrive at the command

../../support/scripts/inc2h.pl 16f873 /usr/local/share/gptuils >p16f873.h

Now make yields

../../bin/sdcc -mpic14 -c -pp16f873  b.c
Processor: p16f873
 *** Saved 1 registers ***
No registers saved on this pass
 *** Saved 1 registers ***
No registers saved on this pass
gplink --map -c -s 16f873.lkr -o b.o b.o
16f873.lkr: No such file or directory

gplink's usage shows that its default linker script path is
/usr/local/share/gputils/lkr. In this directory, I find a 16f873.lkr file,
so I'm not sure why it can't find it also. In any case, I copy 16f873.lkr
to the current directory and run make again. This time I get

../../bin/sdcc -mpic14 -c -pp16f873  b.c
Processor: p16f873
 *** Saved 1 registers ***
No registers saved on this pass
 *** Saved 1 registers ***
No registers saved on this pass
gplink --map -c -s 16f873.lkr -o b.o b.o
error: no target memory available for section ".udata"


I am thinking that I do not have gputils installed correctly and/or the
PIC regression Makefile is out of date. Any suggestions would be
appreciated. (My development environment is Red Hat Linux 9 for IA32)
