Project:Branches: sebhub/rtems-tools:up/rap-relocs to rtems/tools/rtems-tools:main Author: Sebastian Huber ## Summary Closes #1, #43, #44 and #45. **Problem:** `rtems-ld` writes broken RAP files. The RTEMS test `dl06` fails on every simulator BSP that builds it: - An unused undefined `_GLOBAL_OFFSET_TABLE_` stops the link on i386 and microblaze (#43). - Relocations against undefined symbols are dropped but still counted, so the loader reads past the end of the file (#1). - Code and symbols of an object end up at different offsets, for example on i386 (#44). - The relocation type has only 8 bits, which is too small for AArch64 types (#45). **Fix:** One commit per issue. The last commit adds RAP format version 3, which writes the relocation type as a word of its own. `rtems-rap` reads versions 2 and 3. **Review hints:** - The RTEMS loader for version 3 is rtems/rtos/rtems!1575 (rtems/rtos/rtems#5801). The loader still reads version 2. - The `dl06` fix on the RTEMS side is rtems/rtos/rtems!1574. ## Test RTEMS `dl06` with this `rtems-ld`, rtems/rtos/rtems!1574 and the version 3 loader: `END OF TEST` on `aarch64/a53_lp64_qemu`, `arm/xilinx_zynq_a9_qemu`, `i386/pc586-sse`, `microblaze/petalogix_s3adsp1800`, `mips/jmr3904`, `mips/malta`, `powerpc/psim`, `riscv/rv64imafdc`, `sparc/gr712rc`, `sparc/gr740` and `sparc/gr765`. ## AI Details <!-- Make sure you have read our statement at https://www.rtems.org/generative-ai/ --> ### Prompt used None as a single prompt. The work was done in an interactive Claude Code session on the RTEMS Tools tree. Each change was directed and reviewed. ### AI model used Claude Opus 5.5 (claude-opus-5-5), through Claude Code. ### How AI was used for the contribution - ( ) Formatting - ( ) Test creation. - (x) Code comments. - ( ) The entire contribution was generated using AI - ( ) AI code completion such as Copilot in VSCode. The implementation was produced in that session under my direction, and the commit messages were drafted there. ### Access I have not used a product which claims copyright in its output, and I have legitimate access to the one I used. -- View it on GitLab: https://gitlab.rtems.org/rtems/tools/rtems-tools/-/merge_requests/100 You're receiving this email because of your account on gitlab.rtems.org.
