Linux kernel fs/binfmt_elf_fdpic.c supports FDPIC for MMU-less systems. GCC/binutils/qemu support FDPIC ABI for ARM (https://github.com/mickael-guene/fdpic_doc). _ARM FDPIC Toolchain and ABI_ provides a summary. This patch implements FDPIC relocations to the integrated assembler. There are 6 static relocations and 2 dynamic relocations, with R_ARM_FUNCDESC as both static and dynamic. gas requires `--fdpic` to assemble data relocations like `.word f(FUNCDESC)`. This patch adds `MCTargetOptions::FDPIC` and reports an error if FDPIC is not set. _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
