Samuel Neves 0359065018 Another movd/movq inconsistency. 
- Visual Studio <= 2015 does not support AVX-512 either way;
 - Visual Studio 2017 does not tolerate vmovd with 64-bit operands;
 - Visual Studio 2019 does not care.

Some of the SIMD code is still unformatted, so for now I'm only touching
the files that just have a couple small changes.

More movd/movq discrepancies. Fixes #149. (#150) 
This should be irrelevant, but some toolchains will not accept movd with 64-bit arguments.

Hans Henrik Bergan c7c4bfafab fix disabled-optimization -Wall -Werror 
patch by Samuel Neves ( https://github.com/sneves )

if you tried to compile blake3_dispatch.c with
-Wall -Werror -DBLAKE3_NO_SSE2 -DBLAKE3_NO_SSE41 -DBLAKE3_NO_AVX2 -DBLAKE3_NO_AVX512

something like this would happen:

Jack O'Connor 35aa4259bd version 0.3.7 
Changes since 0.3.6:
- BUGFIX: The C implementation was incorrect on big endian systems for
  inputs longer than 1024 bytes. This bug affected all previous versions
  of the C implementation. Little endian platforms like x86 were
  unaffected. The Rust implementation was also unaffected.
  @jakub-zwolakowski and @pascal-cuoq from TrustInSoft reported this
  bug: https://github.com/BLAKE3-team/BLAKE3/pull/118
- BUGFIX: The C build on x86-64 was producing binaries with an
  executable stack. @tristanheaven reported this bug:
  https://github.com/BLAKE3-team/BLAKE3/issues/109
- @mkrupcale added optimized implementations for SSE2. This improves
  performance on older x86 processors that don't support SSE4.1.
- The C implementation now exposes the
  `blake3_hasher_init_derive_key_raw` function, to make it easier to
  implement language bindings. Added by @k0001.
 2020-10-01 10:00:06 -04:00
Jack O'Connor 3d212291b9 add cross_test.sh for the C bindings 
This will let us add big endian testing to CI for our C code. (We were
already doing it for our Rust code.)

This is adapted from test_vectors/cross_test.sh. It works around the
limitation that the `cross` tool can't reach parent directories. It's an
unfortunate hack, but at least it's only for testing. It might've been
less hacky to use symlinks for this somehow, but I worry that would
break things on Windows, and I don't want to have to add workarounds for
my workarounds.

Jack O'Connor 0b13637ae3 fix a couple of big-endianness mistakes in blake3.c 
Kudos to @pascal-cuoq and @jakub-zwolakowski from TrustInSoft for
catching these bugs.

Jack O'Connor 5b22bf57c8 add i586-unknown-linux-musl as a test target 
Samuel noticed that rustc seems to assume (incorrectly?) that all i686
targets support SSE2, but it doesn't make that assumption for i586.
 2020-08-31 18:25:38 -04:00
Jack O'Connor 3c1db55529 add the dynamic check for SSE2 support 
It will be very rare that this actually executes, but we should include
it for completeness.
 2020-08-31 18:25:38 -04:00
Jack O'Connor a79fec7e39 fix a build break on x86 targets without guaranteed SSE2 support 
This is quite hard to trigger, because SSE2 has been guaranteed for a
long time. But you could trigger it this way:

    rustup target add i686-unknown-linux-musl
    RUSTFLAGS="-C target-cpu=i386" cargo build --target i686-unknown-linux-musl

Note a relevant gotcha though: The `cross` tool will not forward
environment variables like RUSTFLAGS to the container by default, so if
you're testing with `cross` you'll need to use the `rustc` command to
explicitly pass the flag, as I've done here in ci.yml. (Or you could
create a `Cross.toml` file, but I don't want to commit one of those if I
can avoid it.)
