Subject: [PATCH] BPF relocations review / refactoring
Date: Thu, 2 Mar 2023 11:25:31 +0000 [thread overview]
Message-ID: <20230302112531.200647-2-cupertino.miranda@oracle.com> (raw)
In-Reply-To: <20230302112531.200647-1-cupertino.miranda@oracle.com>
- Removed not needed relocations.
- Renamed relocations to match llvm and linux kernel.
Relocation changes:
R_BPF_INSN_64 => R_BPF_64_64
R_BPF_INSN_DISP32 => R_BPF_64_32
R_BPF_DATA_32 => R_BPF_64_ABS32
R_BPF_DATA_64 => R_BPF_64_ABS64
ChangeLog:
* bfd/bpf-reloc.def: Created file with BPF_HOWTO macro entries.
* bfd/reloc.c: Removed non needed relocations.
* bfd/bfd-in2.h: regenerated.
* bfd/libbfd.h: regenerated.
* bfd/elf64-bpf.c: Changed relocations.
* include/elf/bpf.h: Adapted relocation values/names.
* gas/config/tc-bpf.c: Changed relocation mapping.
