Subject: [PATCH v2 0/5] gdb/aarch64: Support for FPMR
Date: Tue, 7 Oct 2025 13:31:27 +0100	[thread overview]
Message-ID: <20251007123132.26769-1-Ezra.Sitorus@arm.com> (raw)

From: Ezra Sitorus <ezra.sitorus@arm.com>

The Floating Point Mode Register (FPMR) determines the behaviour of FP8
instructions. This patch series adds support for this register into gdb.

I've run the full testsuite on aarch64-none-linux-gnu, and ran the
gdb.arch tests using Shrinkwrap, which allows me to run Linux on a
model of an Arm system with new features. You can find more information
here: [1].

In v2:
* I've addressed the various comments on formatting/whitespaces
* Testing is simplified - there's less repetition of code. I've also
  removed the remote versions of procedures to run the tests on
  gdbserver remotely.
