Subject: [Buildroot] [PATCH] package/wpewebkit: disable JIT for all MIPS CPUs
Date: Sat, 28 Feb 2026 21:49:02 +0200	[thread overview]
Message-ID: <20260228194903.1908686-1-aperez@igalia.com> (raw)

Change the mips32r6 into a blanket BR2_mips[el] check to disable the
JSC JIT. Upstream removed JIT support for all MIPS processors in
January 2024 [0], and the change trickled down to stable releases
starting on version 2.44.0 [1].

While at it, change the upstream bug links to point to a more
appropriate bug report.
