Subject: [meta-oe][PATCH] luajit: test SITEINFO_BITS instead of maintaining a list of 32bit targets
Date: Wed, 25 Jan 2017 13:43:21 -0800	[thread overview]
Message-ID: <1485380601-6226-1-git-send-email-armccurdy@gmail.com> (raw)

When cross compiling, the word size of the compiler set via HOST_CC
must match the word size of the target. That's achieved by appending
"-m32" to BUILD_CC_ARCH if the target word size is known to be 32bits.

Unfortunately the current list of over-rides (powerpc, x86 and arm)
does not cover all cases (e.g. it ignores MIPS). Using SITEINFO_BITS
is a more generic solution.
