Subject: [PATCH bpf-next v3 09/11] libbpf: Fix accessing program counter on riscv
Date: Fri,  4 Feb 2022 15:50:16 +0100	[thread overview]
Message-ID: <20220204145018.1983773-10-iii@linux.ibm.com> (raw)
In-Reply-To: <20220204145018.1983773-1-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.

Fixes: 3cc31d794097 ("libbpf: Normalize PT_REGS_xxx() macro definitions")
Signed-off-by: Ilya Leoshkevich <iii@linux.ibm.com>
