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
