Subject: [PATCH bpf-next v5 05/10] libbpf: Fix riscv register names
Date: Wed, 9 Feb 2022 03:17:40 +0100 [thread overview]
Message-ID: <20220209021745.2215452-6-iii@linux.ibm.com> (raw)
In-Reply-To: <20220209021745.2215452-1-iii@linux.ibm.com>
riscv registers are accessed via struct user_regs_struct, not struct
pt_regs. The program counter member in this struct is called pc, not
epc. The frame pointer is called s0, not fp.
Fixes: 3cc31d794097 ("libbpf: Normalize PT_REGS_xxx() macro definitions")
