Subject: [PATCH] tcg/tcg-op.c: Fix ld/st of 64 bit values on 32-bit bigendian
hosts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Commit 951c6300f7 out-of-lined the 32-bit-host versions of
tcg_gen_{ld,st}_i64, but in the process it inadvertently changed
an #ifdef HOST_WORDS_BIGENDIAN to #ifdef TCG_TARGET_WORDS_BIGENDIAN.
Since the latter doesn't get defined anywhere this meant we always
took the "LE host" codepath, and stored the two halves of the value
in the wrong order on BE hosts. This typically breaks any 64-bit
guest on a 32-bit BE host completely, and will have possibly more
subtle effects even for 32-bit guests.
Switch the ifdef back to HOST_WORDS_BIGENDIAN.
