Subject: [RFC patch 1/5] RISC-V: Remove riscv-specific sigcontext.h
Date: Mon, 13 Sep 2021 09:41:14 +0800 [thread overview]
Message-ID: <1631497278-29829-2-git-send-email-vincent.chen@sifive.com> (raw)
In-Reply-To: <1631497278-29829-1-git-send-email-vincent.chen@sifive.com>
Remove riscv-specific sigcontext.h so that Glibc can directly use
sigcontext.h provided by the kernel to reduce synchronization work
when new extension support is introduced.
