Hello hpa,
Thank you for your write-up and your information about H. J.
Lu's implementation.
One thing I am still not sure about though is where and how the
segment relocations will be generated in an MZ executable's
MZ header (or in a Windows NE file, etc.) --- since in general
an OS might load an executable at any starting segment in
physical space. These were issues I also tried (in a way)
to tackle in my current R_386_SEGMENT16/_RELSEG16 hack.
Should I take it that a R_386_SEG16 relocation will result in a
relocation entry in the output MZ file? If so, how should the
MZ relocation entries be handled at the linking stage --- e.g.
should they get sections of their own, as with e.g. .rela.iplt?
Do let me know what you think.
Thank you!
