As a back end for gnu cc as has been thoroughly tested and should
work extremely well. We have tested it only minimally on hand written assembly
code and no one has tested it much on the assembly output from the HP
compilers.
The format of the debugging sections has changed since the original
as port (version 1.3X) was released; therefore,
you must rebuild all HPPA objects and libraries with the new
assembler so that you can debug the final executable.
The HPPA as port generates a small subset of the relocations
available in the SOM and ELF object file formats. Additional relocation
support will be added as it becomes necessary.
