Subject: [Patch] Update include/longlong.h to match GCC
Date: Thu, 01 May 2014 15:18:00 -0000 [thread overview]
Message-ID: <bc4d7f87-57da-4931-8f5f-5bf9df04c6af@BAMAIL02.ba.imgtec.org> (raw)
I would like to update include/longlong.h to pick up the latest changes
from GCC and keep this file in sync. I think changes to keep files
in sync are considered pre-approved so if I don't hear any objections
I will go ahead. The changes in GCC that are not yet in the binutils
tree are:
2014-05-01 Steve Ellcey <sellcey@mips.com>
* include/longlong.h: Use 'defined()' to check __mips16.
2014-04-30 Richard Sandiford <rdsandiford@googlemail.com>
* longlong.h (__i386__): Remove W_TYPE_SIZE==64 handling.
2014-04-22 Yufeng Zhang <yufeng.zhang@arm.com>
* longlong.h: Merge from glibc.

* include/longlong.h: Import latest version from GCC tree.
