Subject: [PATCH 00/34] Add clang support for ARM and cleanups
Date: Tue, 25 Mar 2014 16:55:07 +0000 [thread overview]
Message-ID: <1395766541-23979-1-git-send-email-julien.grall@linaro.org> (raw)
Hello all,
The main goal of this patch series is to add support for Clang on ARM.
The work has been done with Clang 3.5 which is not yet release but have
a good support for ARM32. I think clang 3.4 may also be able to compile
Xen but I didn't try.
With the first part of the serie (patch #1-#19 and patch #33), I'm able to boot
Xen compiled by Clang on midway. The patch #33 workaround for a bug in Clang
(http://llvm.org/bugs/show_bug.cgi?id=19199). I'm not sure if the patch would
be acceptable for Xen upstream.
While I was working on Clang 3.5, I played with -Wmissing-prototypes (patch #20-#30)
and discovered some exported functions which were:
- the prototype were not declared before because of a missing include
- never used
Finally the last part of this series (patch #31-33) contains a start of
bug fixes to be able to compile the tools with Clang. I didn't include
the patch https://patches.linaro.org/26826/.
The branch will all the patch applied (+few required patches) can be found here:
git clone git://xenbits.xen.org/people/julieng/xen-unstable.git -b clang
