pdecsub.pas looks like the place to look for, there I also found the
declarations for the other keywords that work with procedures/functions.
I am still not understanding enough of the inner workings of the
compiler so if anybody feels the urge to implement this please go ahead
;-) , for me this would be something for the longterm to try to do it
myself, first I would like to get support for pic32mx done, this burns
more under my fingernails and I am still not atb the end of the learning
curve there.

Maybe the section keyword that was introduced for embedded systems for
variables
(see compiler/pdecvar.pas unit, look for _SECTION and
try_consume_sectiondirective)
should be extended to function/procedure header parsing.
procedure reset; assembler; nostackframe; public name'_reset'; section
'.reset,"ax",@progbits';
would then do all you want.

I had some time this weekend (while beeing grilled by the sun on my

As said before in this thread, I wanted to distribute Code in two
different memory areas because
this needs to be done so that pic32 startup code works correctly.
But when I linked my binary the elf-file had always a startup address
somewhere in the wrong memory
area.
This is what I tried:
procedure reset; assembler; nostackframe; public name'_reset';
asm
.section ".reset,\"ax\",@progbits"
la $k0, _startup
jr $k0 //Jump to startup code
nop
.text
end;
In general, the custom section support in compiler needs a lot of
improvement...
Try the following, maybe it could work:
procedure anyname; assembler; nostackframe;
asm
.section ".reset,\"ax\",@progbits"
.globl _reset
_reset: // <-- correct name here
la $k0, _startup
jr $k0
nop
.text
end;
Regards,
Sergei
I agree that it needs some work. Having a way to specify the section
with a procedure directive would largely be preferable I think. Such a
directive could also be interesting for variables and typed constants
Also, I think
.section ".reset"
should work just fine in most cases
