AT&T <-> Intel assembler converter and indentation program
by Thorsten Hindermann 22 Jan '01

22 Jan '01

Hello together! I have a 2 questions: 1. In the GPC ToDo-list is a point for an AT&T <-> Intel assembler converter. Eike Lange and I discusses to implement this feature in pindent (see anouncement earlier this month). But we are both not very good assembler programmers. The questions: is there is anybody (with very good experience in both assembler languages) who want help us to implement this feature in pindent so please feel free to contribute to this little project. We only talk about inline-assembler and pindent doesn't eat .s-files. Contact us in the GPC- or pindent- (pindent(a)mond.dida.physik.uni-essen.de) mailing-list. Thanx 2. Today I've look in the GPC ToDo-list and I see the indentation program request. If there is any reason to have this point in the list now? Because pindent is in its first version availible (http://mond.dida.physik.uni-essen.de/~pindent/) and Eike and I working on the next version. Thorsten

OK, that's already fewer errors... :-) About the undefined reference to `toCall', `Get_loadpath' and `Moved'. These seem to be identifiers from your code, so I can only guess why they are missing: - You declared them `external' and didn't reference the unit containing them. - They were written in C or assembler and you didn't tell the compiler about it (you can use `{$L foo.c}' or `{$L foo.s}' or specify the file on the command line. - They were written in C or assembler or declared with an explicit `asmname' directive, and upper and lower case letters were mixed up. (Note, while Pascal identifiers are case-insensitive, assembler symbols, including `asmname's, and C identifiers, are case-sensitive.) If this doesn't help you find the problem, I can only help you further if you show me the places in the code where they are defined and used. About the multiple definition of `_p_strrscan'. `_p_strrscan' is the assembler symbol for the RTS routine CStringLastChPos. Do you happen to declare a routine of that name in yuor code? Though it's not reserved, that's currently a known bug that GPC will use the same assembler symbol then, resulting in such a problem. Please use another identifier then. If that's not the case, I don't know what's the problem, without seeing the code. You could try temporarily removing parts of pcamac.pas to find out what's causing the problem...

Oh, pcamac.pas is a unit? I thought it was the main program. To compile a unit, you can use the `-c' option. But normally you don't need to do that at all. Just compile the main program with `--automake', and all units will be compiled when necessary. (Of course, you don't get an executable when compiling just a unit, you need a main program for that -- just like in BP and probably every other compiler.)

Greetings, I think I might have discovered a bug in gpc. A test program follows. John Ollason ------------------- { The following program illustrates a bug discovered in gpc. The program functions correctly with the set 0..31, but with the set 0..32 or greater the second call to card returns zero, and the contents of the set disappear after the first call.

compilation problems

Hello, We have some problems in compilation of BP sources with GPC on Red Hat Linux. The following peice of code in our source is giving copilation problem procvar = procedure; const nilproc : procvar = nil; BP supports assinging pointer values to procedure types and we find that GPc doesnot support it. Expecting your advice on solving the above. regards hari

Hi Tom! I'll forward this to the list, because it might be interesting to others as well.

I removed gtkunit-20001119.tar.gz because this unit is outdated and we have nothing new as stable as the old unit. I hope, we finish the unit at the end of january 2001 :-)) We will give an announcement to the list, where to download. Eike
