Subject: [PATCH v2 0/3] ARM: iwmmxt/pj4 fixes for v7/Thumb-2
Date: Thu, 8 Sep 2011 17:04:11 +0100 [thread overview]
Message-ID: <1315497854-13311-1-git-send-email-dave.martin@linaro.org> (raw)
The iwmmxt and pj4 support code contains some code which isn't
compatible with Thumb-2 and looks possibly inappropriate for v7.
There is also an issue with Makefile rules causing iwmmxt.S to be
built for the wrong architecture.
The Makefile and .S changes for iwmmxt may get folded into a
single patch; they don't make much sense independently any more.
v2 changes:
* Makefile logic changed, so that -march=armv7-a+iwmmxt is
demanded for Thumb-2 kernels, and a warning is printed if the
assembler doesn't support this when buiding a v7 ARM kernel.
