- Pila 1.0 Beta 2 ReadMe
- By Darrin Massena (darrin@massena.com)
- 5 Oct 96
-
- Pila is a 68000 assembler that runs under Windows 95/NT and produces
- Pilot executables. Documentation for Pila is in the HTML file PilaUM.htm.
-
- This version is of a BETA level of quality. That means it includes all
- the documented features and has undergone a fair amount of public testing
- to be sure they work. It also means that there are known bugs and anyone
- using unstressed areas of the program may discover more bugs. If you
- uncover any bugs or have suggestions on how to improve anything in the
- Pila package (the program, documentation, this readme, etc) please send me
- mail at darrin@massena.com. This is a part-time effort for me but I really
- value your feedback and will respond as soon as I can.
-
- Consult http://www.massena.com/darrin/pilot/pila.htm for an up-to-date
- list of known bugs and other Pila status.
-
- KNOWN BUGS
-
- - Certain invalid syntaxes will cause the assembler to crash.
- For example defining an address operand like (a6,6) instead of 6(a6)
- will crash. (reported by Greg Hewgill)
-
- - Pila reports the compressed size of an application's data section as
- being larger than the uncompressed size! This is actually not a bug
- but a fact because Pila does not implement complete data section
- compression yet. The 'compressed' size is larger (only 16 byte or so)
- because of overhead the PalmOS' compression format introduces.
- Presumably, when complete compression is implemented the savings will
- more than offset the overhead
-
- REVISION HISTORY
-
- ALPHA 1 (7 Aug 96)
- - First release!
-
- BETA 1 (10 Sep 96)
- - added Wes Cherry's PilRC (0.71), a tool for creating Pilot resources,
- to the Pila package
- - added Bill Hunt's PilDis (Alpha 1), a tool for disassembling Pilot
- code resources
- - added Sample.rcp file to demonstrate resource creation. Sample.rcp
- replaces mbar1.bin and tfrm1.bin which are removed
- - added Sample.bat file to build Sample.prc
- - added special equates to Pilot.inc for the serial library APIs
- - implemented source file name printing in error messages
- - implemented a statistics dump after successful assembly. Displays
- sizes for code, data, resource, and the entire PRC. Keep those PRCs
- small!
- - implemented a very minor Startup.inc optimization
- - fixed bug that was causing line numbers to be offset by one inside
- include files and off by another one in the 'including' file
- - fixed a HUGE bug that caused the data section and A5 register to be
- improperly initialized
- - updated Sample.asm to demonstrate data section access (amongst other
- things)
- - updated PilaUM.htm to incorporate various suggestions I received
- from Alpha testers, including a new section on the PalmOS API
- calling convention and a pointer to an online version of the
- Motorola 680x0 Programmer's Reference Manual -- get it!
-
- Beta 2 (2 Oct 96)
- - added 'align' directive for aligning code/data on user-defined boundaries
- - added 'list' directive for enabling/disabling listing output
- - added include path support via PILAINC environment variable
- - added Copilot-compatible code symbol generation. Specify "-s" and your
- app's code symbols will be available while debugging under Copilot
- - updated Startup.inc to use Wes' new directives (see below)
- - updated documentation
- - changed all errors to be output to stdout, rather than a mix of stdout/
- stderr
- - added Wes Cherry's PilRCUI, a tool for previewing Pilot form resources,
- to the Pila package
- - updated to Wes Cherry's PilRC version .8
-
- Wes Cherry has been extending Pila and has added many new features to make
- assembly language programming easier and less bug-prone. His new directives
- and syntax support procedure parameter definition, procedure calling, trap
- calling, local and global variable definition, and structure definition and
- usage. Wow!
-
- - the new directives are: call, systrap, syslibtrap, local, global, proc,
- beginproc, endproc, struct, endstruct, and sizeof
- - added documentation for new directives to PilaUM.htm! Updated examples,
- etc to show new syntax
- - Pila names (e.g., labels, equates) are now case sensitive. Instructions
- and directives remain case insensitive
- - updated Pilot.inc to use the new structure syntax. Several incorrect
- structure member offsets were fixed in the process
- - updated Sample.asm to use the new directives
- - fixed the 'end' directive to work as it should and be optional
