Subject: [PATCH v9 07/11] unwind_user/sframe/x86: Enable sframe unwinding on x86
Date: Wed, 16 Jul 2025 21:28:55 -0400 [thread overview]
Message-ID: <20250717012936.785935784@kernel.org> (raw)
In-Reply-To: 20250717012848.927473176@kernel.org
From: Josh Poimboeuf <jpoimboe@kernel.org>
The x86 sframe 2.0 implementation works fairly well, starting with
binutils 2.41 (though some bugs are getting fixed in later versions).
Enable it.
