Elf36 Specification:
- Do we want to adjust SHN_LORESERVE up to SHN_HIRESERVE, including SHN_XINDEX, to
account for the fact that we have 2 more bits available in Elf36_Half?
I'm inclined not to change, but to allow indices in [SHN_HIRESERVE+1,PDP10_UINT18_MAX]
as-is without going through SHN_XINDEX.
- Same question for PN_XNUM?
- Summarize the differences between Elf32 and Elf36 in a document somewhere.
pdp10-stdio:
- Handle non-seekable output files better (i.e., allow 8to9 to write to stdout)
Tools:
- size: implement it
- strip: implement it
- ld: implement it
- readelf: add support for relocs
- readelf: add support for program headers
- pdp10-opcodes.{h,c}: rewrite completely
- as:
* add line-comment character, e.g. '#'
+ use it in doc/MUUO.txt
+ use it in as/tests/*.s
+ add license boilerplate to the above files
* support .ident:
+ change strtab to have a finalizer which returns an image array,
+ use standard output_section for strtab
+ move strtab to tunit
+ have .ident append string to .comment strtab
+ finalize .comment strtab before output()
* add support for named sections
* add support for sub-sections
* add support for data directives (.word, .asciz, etc)
* add support for relocs
* add support for extended opcodes (emit second opcode after current .text section)
* add support for symbolic references to 30 or 36-bit addresses via something like %hi/%lo functions
