I don't understand how they are getting this problem. Pairing .text/.rodata with a .cpp file worked fine to me on my hit_and_run repo.

ieee802dot11ac commented 1 month ago

It appears using o_as_suffix sidesteps this issue entirely, as i.e. src/utl/PrnStream.cpp becomes src/utl/PrnStream.o.

ethteck commented 1 month ago

were you getting .cpp.o @AngheloAlf ? if so there's still probably a bug or something. I can try to clone the repo and check it out

AngheloAlf commented 1 month ago

I definitely use o_as_suffix, that must be why I'm not getting this issue

AngheloAlf commented 1 month ago

I just checked this on my hit_and_run repo again. I can't reproduce the issue even when turning off o_as_suffix.

My the relevant entries from my yaml looks like this:

      - [0x062648, cpp, code/allps2main]
      # ...
      - [0x35D010, .rodata, code/allps2main]

Using o_as_suffix: True the generated linker script looks like this:

        build/us_2003_07_10/src/code/allps2main.o(.text);
        /* ... */
        build/us_2003_07_10/src/code/allps2main.o(.rodata);

Using o_as_suffix: False the generated linker script looks like this:

        build/us_2003_07_10/src/code/allps2main.cpp.o(.text);
        /* ... */
        build/us_2003_07_10/src/code/allps2main.cpp.o(.rodata);

@ieee802dot11ac Actually your yaml looks a bit wrong. Each one of your sections are to be placed on different top-level segments, which prevents splat from being able to pair them. All of them should be present on your main segment just as a bunch of other entries. You can see this on my my hit_and_run repo, the data, rodata, etc sections are just entries of the only important segment

It looks like the root issue has been resolved, so I'm gonna close this for now. Feel free to reply if this is still a problem or open a new one if you run into something else!
