May 12, 2002 -- gputils-0.10.3 Released and gputils-extra-0.0.2 Released

At the request of a user, man pages have been generated for gputils. These pages are not considered a substitute for the manual. The header files and linker scripts have been updated. Changes were incorporated for the Code Warrior port of gpasm.

A new branch in cvs has been created for the relocatable object file support. This branch will become 0.10.4 or 0.10.5. A notice will be posted when it is ready for the users.

April 4, 2002 -- gputils-0.10.2 Released

gpasm now generates messages, warnings, and errors for various invalid arguments to instructions. Typically because the argument is not within the valid range. Additionally, gpasm now generates messages and warnings related to setting the bank and page bits.

February 24, 2002 -- gputils-0.10.1 Released

This release includes a major overhaul of macros. The macros are now stored as text instead of a parsed structure. This text is inputted into the lexer each time the macro is called. Several macro related problems were also fixed.

January 24, 2002 -- gputils-extra-0.0.1 Released

The is the first release of the new extras package. Anything which doesn't fit into gputils will go into this new package. The package is distributed in source only and does not install.

January 20, 2002 -- gputils-0.10.0 Released

This release is basically gpasm-0.9.14 with bug fixes. Additionally, there are some new tools. However, these new tools are not complete, so they are not installed. Please see the ChangeLog for details on the bug fixes.

January 13, 2002 -- gputils imported to cvs

The new package has been imported to cvs. The first release should occur in the coming weeks.

December 12, 2001 -- gputils package created

A new linker and lib tool are under development. These new tools along with gpasm will be distributed in a new package gputils, GNU PIC Utilities.

November 20, 2001 -- gpasm-extra announced

A new package, gpasm-extra, is being put together. See the description above for details.

October 31, 2001 -- v0.9.14 Released

The path to the header files is automatically loaded into the include paths list. This means that you no longer need to add "-I /usr/local/share/gpasm/header" to gpasm to use the provided header files. This feature can be disabled by adding "--disable-path" when configuring. One key point, gpasm always checks the local directory for includes before checking any of the include paths.

The fill directive will now allow a line of assembly as an argument. The argument must be enclosed by parentheses.

fill (goto start), NextBlock - $

Several bugs were fixed in the lexer. These were related to malformed input files confusing gpasm about when pass 1 could be ended. One of the file problems was a missing newline before the end of file marker. The bugs have been fixed so they shouldn't cause any more problems. Gpasm will warn the user when one of these files is processed. If you receive the warning, open the input file in vi and save it. Vi will fix the problem. The test has been disabled on win32 systems because of inconsistencies in the editors and file formats.

October 6, 2001 -- v0.9.13 Released

The release is mainly to add several new processors. Additionally, new header files to support the processors were added.

A new feature is "list n=0". This will prevent page breaks in the source code section of the list file. A related bug was also fixed. All numeric arguments to the list directive are now interpretted as decimal regardless of the current radix setting.

September 8, 2001 -- v0.9.12 Released

This release makes more improvements to the preprocessor. A brief description of the features are in the ChangeLog. A more comprehensive explaination will be included in the updated documentation in the next minor release.

In addition to the new features, several bug fixes were incorporated. The most significant was the replacement of the old "can't evaluate expression" error message with more meaningful messages.

I was surprised to see that more than 400 people downloaded the MinGW32 port of gpasm 0.9.11. No one has reported any bugs in the port. Because of the large number of downloads, the MinGW32 distribution will continue to be generated.

More progress was made with the new macro implementation. With these changes all of the known macro defiencies have been fixed. These changes will be distributed in the next minor release (there might be a couple more micros releases first).

August 17, 2001 -- MinGW32 binary

For the next few releases a win32 binary will be provided. If this distribution is popular the releases will continue.

August 14, 2001 -- v0.9.11 Released

This release primarily fixes bugs and adds features to the gpasm preprocessor. This is all ground work for the up coming macro implementation changes.

With the changes in this release, gpasm should correctly identify any opcode, directive, or macro incorrectly placed in column 1. It will also substitute any symbol found in column 1 that appears in the #defines table.

August 4, 2001 -- v0.9.10 for win32 experiment

A gpasm user has decided to attempt a gpasm port to win32 using Microsoft Visual C++ 6.0. To my knowledge this has never been attempted. I have done this using the Borland compiler. In order to help the user, the data from the Borland port has been added. The data is available in the "What Platforms are Supported?" section of this page.

The Borland data will be added to the distribution sometime in the future. If Visual C port works that data could be added as well.

Try out the Borland port. If you have an opinion send me an email <craigfranklin@users.sourceforge.net>.

July 30, 2001 -- v0.9.10 Released

I experienced a moment of terror on July 29th, when my new 0.9.9 release generated a core dump. I made the 0.9.9 release inactive and investigated the problem. It turned out to be a really old bug. I had already stopped the presses, so I decided to just make a new release that included the fix.

July 28, 2001 -- v0.9.9 Released

This release fixes some minor bugs and cleans up some of the old code. Most of the changes probably won't effect users who are not writing new code. For those that are, several new tests should help to catch some problems before they occur. For example, all labels are checked to see if they are a resevered word. If they are a warning is generated and the text is treated accordingly. This test should help catch typos.

July 17, 2001 -- v0.9.8 Released

gpasm will now expand macros in the listing and cod files. The real advantage of this is gpsim will jump to the macro or while loop source when stepping through the code. If you like the old way that gpasm operated add a "NOEXPAND" or "LIST x=OFF" to the top of your source code. Another way is to add the argument "e=OFF" to gpasm.

New with this release is an optional i386 rpm distribution. Make sure you uninstall any previous gpasm installation before installing the rpm. This can be accomplished by running a "make uninstall" on 0.9.7 or by removing the binaries from /usr/local/bin and the data from /usr/local/share/gpasm. The only difference the users should notice is the headers are now located in /usr/share/gpasm/header.

June 17, 2001 -- v0.9.7 Released

This one has some new features. New operators have been implemented. i++, i--, i+=1 are some examples.

There is also some new eye candy in this one as well. A memory map is now produced as part of the list file. The number of program words used by the file is also reported.

Some work was done to make gpasm a little more friendly to non Linux systems. More can probably be done in this area. If you have to patch gpasm to compile it, please send me the data. I will evaluate it for possible inclusion in future gpasm releases <craigfranklin@users.sourceforge.net>.

May 30, 2001 -- v0.9.6 Released

This release primarily fixes bugs submitted into the bug tracker. Most of them are minor. The one some of you may have experienced is failure of 0.9.5 to compile due to missing getopt_long(). This problem occurs on Solaris and some BSDs. This version of gpasm will configure around your system. If you don't have it, gpasm won't use it.

The first version of the object file viewer is included in this release. It is not a final version. Please hold off on the bug reports for a few weeks at least. The basic functions of the viewer work, but there are still some holes to fill. Completion of this viewer will lead directly into object file generation for gpasm.

May 18, 2001 -- v0.9.5 Released

The release was completed on May 13th, so this is probably old news for many of you.

Much was accomplished, but nothing that I planned for. The main changes are related to getting some case sensitivity problems solved. The problem was that the mneumonics in special.inc are implemented as macros. This created some case sensitivity headaches. This release solves all of the problems (at least the ones I know about).

The solution was to move the functionality of special.inc into the source code. With 0.9.5 you can safely remove special.inc from /usr/local/share/gpasm. This can also be accomplished be running a "make uninstall" on 0.9.4 before installing 0.9.5.

The macro expansion and object file viewer are in about the same shape they were a couple of weeks ago. They are still at the top of the list. I will try to make finish them for the next release. I won't make any promises though.

April 22, 2001 -- v0.9.4 Released

More compatibility changes ... most are minor. 460 of 501 gpasm test files are now passing.

Many things are in the queue for 0.9.5. Most are very close to being complete, but weren't ready to make the 0.9.4 cut. These things include:

  • A utility to view the contents of Microchip's object files. The next step in adding object file support to gpasm.

  • Macro expansion. It has been on the back burner for some time. I just want to get it off of my "To Do" list.

March 17, 2001 -- v0.9.3 Released

The work has continued on the Microchip test files. 431 of 501 gpasm test files are now passing.

March 4, 2001 -- v0.9.2 Released

I have spent most of the last week working on the Microchip test files. They provided > 500 asm files for testing MPASM. The first time I tested gpasm, only 53 of the files passed. With the changes made in 0.9.2 we are up to 387. Not 500, but much better than 53. The rest of the 0.9.x series will concentrate on getting closer to 500 files passing.

The linker support was put on hold when the Microchip test files came in. I felt it was better to fix bugs than to add features. Not to worry, I will pick it back up in a few weeks. Currently, the linker can read Microchip's object files and combine the data into one hex file. (All of the important steps in between are skipped.)

Carlos Nieves has provided a patch which adds the 17cxx family. It will be part of 0.9.3.
