[openssl-dev] [openssl.org #4397] BUG: 1.0.2g fails to build on Mac OS X 10.6.8 due to 0b assembly literals

[Clemens Lang via RT]

Some older versions of OS X (10.6.8 "Snow Leopard" and possibly below)
ship with a toolchain that is based on an old version of the GNU
assembler, which does not support binary literals. Assembling an
expression that contains a 0b00011011 literal will cause a warning and
treat the immediate as 0.

This makes the build fail:

sha1-x86_64.s:1243:missing or invalid immediate expression `0b00011011' taken as 0
sha1-x86_64.s:1243:suffix or operands invalid for `pshufd'
sha1-x86_64.s:1245:missing or invalid immediate expression `0b00011011' taken as 0
sha1-x86_64.s:1245:suffix or operands invalid for `pshufd'
sha1-x86_64.s:1395:missing or invalid immediate expression `0b00011011' taken as 0
sha1-x86_64.s:1395:suffix or operands invalid for `pshufd'
sha1-x86_64.s:1396:missing or invalid immediate expression `0b00011011' taken as 0
sha1-x86_64.s:1396:suffix or operands invalid for `pshufd'
make[2]: *** [sha1-x86_64.o] Error 1

An easy workaround is using hexadecimal literals, which are supported by
the toolchain. Joshua Root has prepared a patch that I have sent as a
pull request at
  https://github.com/openssl/openssl/pull/792

Please pull to avoid breaking openssl for users on Mac OS X 10.6.8.
