Subject: Fix build error for aarch64 big endian.
X-Git-Tag: OpenSSL_1_1_1d~111
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=5a63e155ff115f9684a43d8d6034e63e189436d3;p=oweals%2Fopenssl.git

Fix build error for aarch64 big endian.

Modified rev to rev64, because rev only takes integer registers.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90827
Otherwise, the following error will occur.

Error: operand 1 must be an integer register -- `rev v31.16b,v31.16b'
