[PATCH 5/5] aarch64: Enable building the aarch64 cipher assembly for windows
Martin Storsjö

Thu Mar 22 09:56:15 CET 2018
Don't require .type and .size in configure; we can make
them optional via a preprocessor macro.
This is mostly a mechanical change, wrapping the .type and .size
directives in an ELF() macro, with two actual manual changes
(when targeting windows):
- Don't load global symbols via a GOT (in chacha20)
- Don't use the x18 register (in camellia); back up and restore x19
in the prologue/epilogue and use that instead (on windows only).
x18 is a platform specific register; on linux, it's free to be used
by user code, while it's reserved for platform use on windows and
darwin.
Signed-off-by: Martin Storsjö <martin at martin.st>

This isn't strictly necessary for building libgcrypt for windows
on aarch64; previously configure concludes that the assembly can't
be built since the .type and .size directives don't work. This
just allows using more of the existing assembly routines.
This also probably has the effect that the same assembly gets
enabled when targeting darwin (iOS), but building with assembly
enabled doesn't work for darwin anyway (even prior to this change,
since darwin requires an extra leading underscore on all symbols,
while the mpi/aarch64 code gets automatically enabled).
