There are leading null bytes on output with gpc-20041017. $ gpc -v Reading specs from /usr/local/lib/gcc-lib/ia64-unknown-linux-gnu/3.3.3/specs Configured with: ../gcc-3.3.3/configure --enable-languages=c,p : (reconfigured) ../gcc-3.3.3/configure --enable-languages=c,pascal Thread model: posix gpc version 20041017, based on gcc-3.3.3 $ cat nullbytes.pas program main; begin writeln(1.0:20:10); end. $ gpc nullbytes.pas $ ./a.out | od -x 0000000 0000 0000 2020 2020 2e31 3030 3030 3030 0000020 3030 3030 000a 0000025 I'd prefer if there were spaces :-) Regards Thomas

PGCC
by Silvio a Beccara 17 Nov '04

17 Nov '04

Hi, I just found about PGCC, a version of GCC specially optimised for Pentium processors. Anybody ever thought about making GPC work using PGCC as a backend, so as to take profit of the (supposed) optimisations and speed gain? Regards Silvio a Beccara

working with char driver as with the file in GPC
by Igor Marnat 16 Nov '04

16 Nov '04

Hello dear List! Unfortunately there is no possibility at the moment to search through list-archives. Perhaps someone could give me an advise. I'd like to communicate with the char device driver which is realised as a file. In C I can just make "dsp_fd = open(dsp_devname, O_RDWR|O_SYNC)" and then work with it all the time using "write(fd, (const void*)msg, nbytes)" and read respectively without additional activities. How should I use it in GPC? The only way I see is to Assign (dsp_fd, dsp_devname) and then Rewrite it when I have to write to and Reset it when I need to read from. Is it the right way from the point of view of the system performance? Or should I better create an interface with file written in C to avoid the Reset and Rewrite operations? Thanks, regards, Igor mailto:marny@rambler.ru

unbalanced comment bug
by Russell Whitaker 13 Nov '04

13 Nov '04

Hi Found a rather trivial bug, shown here as { { }, the original was a typo: { ) { }. ( so I need new glasses ). program bug; begin { this writeln("OK"); exit; { is a bug } writeln("fail"); end. Russ p.s. built gpc with gcc-3.3.5, no errors in test suite. good.

GPC web site is back
by Frank Heckenbach 10 Nov '04

10 Nov '04

Hi everybody, I am happy to announce that the GPC web site <http://www.gnu-pascal.de> is back online, after several weeks of problems on the server. The current GPC beta release (20041017) is on the download page. Previous alphas/betas between 2.1 and this one have been omitted since I'd have to reconstruct them from my archives and verify them to be trushworthy, and I don't think it's worth the effort. If there are serious problems with 20041017, I'd rather fix them, so everyone can ugprade. Thanks to Eike Lange and Benedikt Wildenhain for helping set up the server again and to G-N-U GmbH for hosting the current GPC beta release in the meantime.

Cross compiling for Mach-O Darwin

It may be interesting to note that yesterday a cctools package has been released that can be used to cross compile and link Mach-O Darwin binaries on Linux, see the odcctools mailing list archives <http://www.opendarwin.org/pipermail/odcctools/2004-November/ 000034.html> of the opendarwin project <http://www.opendarwin.org>.

Environment variables on Mac OS X
by Adriaan van Os 01 Nov '04

01 Nov '04

As discussed before, shared libraries on Mac OS X can not reference the environ variable directly, where applications can. This is a show stopper on Mac OS X, because of the internals of autoconf and because the environ variable is referenced in gpc's runtime library. To solve this problem, I apply the following patch: --- gcc/p/rts/rts.c.orig Wed Apr 16 01:58:46 2003 +++ gcc/p/rts/rts.c Fri Jun 6 11:35:50 2003 @@ -195,7 +195,15 @@ extern int errno; #endif -#if defined (HAVE_ENVIRON) || defined (environ) +/* needed by Mac OS X */ +#if defined (__MACH__) && defined(__APPLE__) +#include <crt_externs.h> +#endif + +/* on Mac OS X the environ variable can not be referenced in shared libraries */ +#if defined (__MACH__) && defined(__APPLE__) +#define environ (*_NSGetEnviron()) +#elif defined (HAVE_ENVIRON) || defined (environ) #if !defined (environ) && !defined (ENVIRON_DECLARED) extern char **environ; #endif I would be grateful if this patch is merged with gpc's sources. Regards, Adriaan van Os

ANN id2id-20 now available
by CBFalconer 30 Oct '04

30 Oct '04

A replacement for the original version. This does not avoid comments and strings, and uses different algorithms. The hashlib package is a prerequisite, and supplies the storage. This is a complete rewrite, in a different language and thus begins life as version 2.0 of id2id. Id2id reads a list of idpairs in the form of lines holding oldname newname and then applies all those changes to the file specified. It does this with a single pass through the file, and thus is almost as quick as simply copying the file. Unlike a normal text replacement in an editor, id2id only operates on complete identifiers. Thus it cannot be used to replace prefixes or suffixes. An identifier is anything that begins with '_' or any letter, and continues for all following characters until a non '_', letter, or digit. The primary purpose is to make compatible changes across a complete set of files. The process of controlling the files modified is left for a supervisory script. Another use is when learning another program. Identifiers can be changed to something more understandable. As more and more of the program is understood, the idpairs file can be enhanced, always maintaining the original source unchanged This can also be applied to the output of a disassembler. The -r switch reverses the meanings of the columns of the idpairs file, and thus can often be used to recreate the original file. BEWARE - this is not always possible. In particular it is not possible if a 'newname' already existed in the original file. Copyright (C) 2004 by C.B.
