From: zengxiao <zengx...@eswincomputing.com> Hi all RISC-V folks:
When riscv-objdump is used to generate dwarf information, problems are found, like: DW_CFA_??? (User defined call frame op: 0x3c) This error is related to that riscv-objdump does not follow the riscv R_RISCV_SUB6 standard. Riscv-readelf is correct because it follows the R_RISCV_SUB6 standard. There are test cases in https://github.com/zeng-xiao/gnu-bug-fix/tree/main/EG-769 that describe the error in detail. zengxiao (1): RISC-V: Make R_RISCV_SUB6 conforms to riscv abi standard bfd/elfxx-riscv.c | 7 +++++ .../testsuite/binutils-all/riscv/dwarf-SUB6.d | 31 +++++++++++++++++++ .../testsuite/binutils-all/riscv/dwarf-SUB6.s | 12 +++++++ 3 files changed, 50 insertions(+) create mode 100644 binutils/testsuite/binutils-all/riscv/dwarf-SUB6.d create mode 100644 binutils/testsuite/binutils-all/riscv/dwarf-SUB6.s -- 2.34.1
