 1.8  05-Sep-2023  mrg apply previous to just GCC.
 1.7  05-Sep-2023  mrg apply -Wno-maybe-uninitialized to chacha_sse2.c.

there's a clearly initialised memory region that is claimed as
being maybe uninitialised, and this test-build version of it
triggers it while the normal build doesn't.
 1.6  08-Sep-2020  jakllsch Acknowledge clang warning for NEON cipher code on aarch64eb

We've already made the nonportable vector initializations portable; the
code works on aarch64eb.
 1.5  17-Aug-2020  riastradh Make the AES and ChaCha NEON tests work in softfloat userland.

(`Softfloat' here refers to the ABI, which of course may be running
on a CPU with NEON.)
 1.4  16-Aug-2020  martin Restrict the NEON code to v7hf - the softfloat toolchain does not like
it (nor is it likely to work if there is no FPU present).
 1.3  28-Jul-2020  riastradh Implement 4-way vectorization of ChaCha for armv7 NEON.

cgd performance is not as good as I was hoping (~4% improvement over
chacha_ref.c) but it should improve substantially more if we let the
cgd worker thread keep fpu state so we don't have to pay the cost of
isb and zero-the-fpu on every 512-byte cgd block.
 1.2  27-Jul-2020  riastradh Enable ChaCha NEON code on armv7 too.

The 4-blocks-at-a-time assembly helper is disabled for now; adapting
it to armv7 is going to be a little annoying with only 16 128-bit
vector registers.

(Should also do a fifth block in the integer registers for 320 bytes
at a time.)
 1.1  25-Jul-2020  riastradh Add kernel ChaCha test to exercise all available implementations.
