RTEMS Tools | rap: The format cannot hold AArch64 relocation types (#45)

[Sebastian Huber (@sebhub)]

Issue created by Sebastian Huber: https://gitlab.rtems.org/rtems/tools/rtems-tools/-/work_items/45



A relocation record of a RAP file holds the ELF relocation type in bits 7:0 of its info word.  The AArch64 relocation types start at 257, for example `R_AARCH64_CALL26` is 283.  The upper bits of the type overlap the section index or the string offset in bits 30:8.  An AArch64 RAP file thus carries wrong types and wrong symbol names, and the load of `dl06` of RTEMS fails with "global symbol not found: l_o2_func2".

The format needs a field of its own for the type.  This requires a new format version which rtems-ld, rtems-rap and the libdl loader of RTEMS agree on.

Found while running the RTEMS test suite on eleven simulators.  This description was created with Claude Code assistance.
