Subject: [PATCH,V1 0/1] RISC-V: Make R_RISCV_SUB6 conforms to riscv abi standard
Date: Tue, 15 Nov 2022 14:51:58 +0800 [thread overview]
Message-ID: <20221115065159.2353620-1-zengxiao@eswincomputing.com> (raw)
From: zengxiao <zengxiao@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.
