Quoting from http://gcc.gnu.org/onlinedocs/gcc/Extended-Asm.html:

"You can put multiple assembler instructions together in a single asm
template, separated by the characters normally used in assembly code for the
system. A combination that works in most places is a newline to break the
line, plus a tab character to move to the instruction field (written as
‘\n\t’). Sometimes semicolons can be used, if the assembler allows semicolons
as a line-breaking character. Note that some assembler dialects use semicolons
to start a comment."

On OS X, neither __powerpc__ nor __ppc__ is defined on PPC64, so the
asm code was only being used on PPC32.

The upcoming BCP document recommends GCM as the default.

Some truncated HMAC test failing right now.
