Subject: [PATCH v2 22/24] linux-user: permit RISC-V CFI dynamic entry in VDSO
Date: Mon, 29 Jul 2024 10:53:24 -0700	[thread overview]
Message-ID: <20240729175327.73705-23-debug@rivosinc.com> (raw)
In-Reply-To: <20240729175327.73705-1-debug@rivosinc.com>

RISC-V CFI use new processor-specific dynamic entry in ELF. Permit it in
VDSO post-processing script.
