- Wellcome to the MacOS port of FreePascal (FPC)
- ==============================================
- It is considered under construction, at the moment.
- Please note that compiling must be done on a platform
- supported by FPC, e g a PC. Then the generated assemble files
- is to be transfered to a Macintosh with MPW installed.
- For compiling with FPC, use it as for other operating systems
- and add these options:
- -Tmacos # target macos
- -dpowerpc
- -al # dont delete asm output
- -s # dont generate executable
- Note that at the moment, FPC yells about not supporting
- creating of executables at the platform, nevertheless
- it creates all asm files to produce an application on the Mac.
- Use MPW to assemble and link the output from FreePascal
- For PPCAsm, use options:
- -case on
- For PPCLink, use options
- -dead on
- -tocdataref off
- -m program_init
- Note on the compiler implementation
- ===================================
- Procedure pointers
- ------------------
- The entries in the transition vector is used as procedure pointers.
- That is the symbol xxx[DS].
- Global variables
- ----------------
- Currently all global variables are indirect, that is the entry in
- the TOC is always a pointer to data. (In the future small data items
- may be stored directly in the TOC, but I have not found out how this
- is supported by PPCLink.)
- Thus all references to globals are via a construct like:
- lwz rX, yyy[TC](r2) ;loads a pointer to a global into rX
