aarch64 support. This is an initial cut at aarch64 support. I have only qemu to test it however—hopefully hardware will be coming soon. This also affects 32-bit ARM in that aarch64 chips can run 32-bit code and we would like to be able to take advantage of the crypto operations even in 32-bit mode. AES and GHASH should Just Work in this case: the -armx.pl files can be built for either 32- or 64-bit mode based on the flavour argument given to the Perl script. SHA-1 and SHA-256 don't work like this however because they've never support for multiple implementations, thus BoringSSL built for 32-bit won't use the SHA instructions on an aarch64 chip. No dedicated ChaCha20 or Poly1305 support yet.

Add ppc64le vector implementation of SHA-1. This change contains a C implementation of SHA-1 for POWER using AltiVec. It is almost as fast as the scalar-only assembly implementation for POWER/POWERPC family in OpenSSL but it is easier to maintain and it allows error checking with tools like ASAN. This is tested only for ppc64le. It may nor may not work for other platforms in the POWER/POWERPC familiy. Before: SHA-1 @ 16 bytes: ~30 MB/s SHA-1 @ 8K: ~140 MB/s After: SHA-1 @ 16 bytes: ~70 MB/s SHA-1 @ 8K: ~480 MB/s Change-Id: I790352e86d9c0cc4e1e57d11c5a0aa5b0780ca6b Reviewed-on: https://boringssl-review.googlesource.com/12203 Reviewed-by: Adam Langley <agl@google.com> Commit-Queue: Adam Langley <agl@google.com> CQ-Verified: CQ bot account: commit-bot@chromium.org <commit-bot@chromium.org>

int SHA1_Init(SHA_CTX *sha) {
memset(sha, 0, sizeof(SHA_CTX));
Improve crypto/digest/md32_common.h mechanism. The documentation in md32_common.h is now (more) correct with respect to the most important details of the layout of |HASH_CTX|. The documentation explaining why sha512.c doesn't use md32_common.h is now more accurate as well. Before, the C implementations of HASH_BLOCK_DATA_ORDER took a pointer to the |HASH_CTX| and the assembly language implementations took a pointer to the hash state |h| member of |HASH_CTX|. (This worked because |h| is always the first member of |HASH_CTX|.) Now, the C implementations take a pointer directly to |h| too. The definitions of |MD4_CTX|, |MD5_CTX|, and |SHA1_CTX| were changed to be consistent with |SHA256_CTX| and |SHA512_CTX| in storing the hash state in an array. This will break source compatibility with any external code that accesses the hash state directly, but will not affect binary compatibility. The second parameter of |HASH_BLOCK_DATA_ORDER| is now of type |const uint8_t *|; previously it was |void *| and all implementations had a |uint8_t *data| variable to access it as an array of bytes. This change paves the way for future refactorings such as automatically generating the |*_Init| functions and/or sharing one I-U-F implementation across all digest algorithms.

#define HASH_BLOCK_DATA_ORDER sha1_block_data_order
Use the straight-forward ROTATE macro. I would hope any sensible compiler would recognize the rotation. (If not, we should at least pull this into crypto/internal.h.) Confirmed that clang at least produces the exact same instructions for sha256_block_data_order for release + NO_ASM. This is also mostly moot as SHA-1 and SHA-256 both have assembly versions on x86 that sidestep most of this. For the digests, take it out of md32_common.h since it doesn't use the macro. md32_common.h isn't sure whether it's a multiply-included header or not. It should be, but it has an #include guard (doesn't quite do what you'd want) and will get HOST_c2l, etc., confused if one tries to include it twice.

Improve crypto/digest/md32_common.h mechanism. The documentation in md32_common.h is now (more) correct with respect to the most important details of the layout of |HASH_CTX|. The documentation explaining why sha512.c doesn't use md32_common.h is now more accurate as well. Before, the C implementations of HASH_BLOCK_DATA_ORDER took a pointer to the |HASH_CTX| and the assembly language implementations took a pointer to the hash state |h| member of |HASH_CTX|. (This worked because |h| is always the first member of |HASH_CTX|.) Now, the C implementations take a pointer directly to |h| too. The definitions of |MD4_CTX|, |MD5_CTX|, and |SHA1_CTX| were changed to be consistent with |SHA256_CTX| and |SHA512_CTX| in storing the hash state in an array. This will break source compatibility with any external code that accesses the hash state directly, but will not affect binary compatibility. The second parameter of |HASH_BLOCK_DATA_ORDER| is now of type |const uint8_t *|; previously it was |void *| and all implementations had a |uint8_t *data| variable to access it as an array of bytes. This change paves the way for future refactorings such as automatically generating the |*_Init| functions and/or sharing one I-U-F implementation across all digest algorithms.

Fix integer types in low-level hash functions. Use sized integer types rather than unsigned char/int/long. The latter two are especially a mess as they're both used in lieu of uint32_t. Sometimes the code just blindly uses unsigned long and sometimes it uses unsigned int when an LP64 architecture would notice.

Improve crypto/digest/md32_common.h mechanism. The documentation in md32_common.h is now (more) correct with respect to the most important details of the layout of |HASH_CTX|. The documentation explaining why sha512.c doesn't use md32_common.h is now more accurate as well. Before, the C implementations of HASH_BLOCK_DATA_ORDER took a pointer to the |HASH_CTX| and the assembly language implementations took a pointer to the hash state |h| member of |HASH_CTX|. (This worked because |h| is always the first member of |HASH_CTX|.) Now, the C implementations take a pointer directly to |h| too. The definitions of |MD4_CTX|, |MD5_CTX|, and |SHA1_CTX| were changed to be consistent with |SHA256_CTX| and |SHA512_CTX| in storing the hash state in an array. This will break source compatibility with any external code that accesses the hash state directly, but will not affect binary compatibility. The second parameter of |HASH_BLOCK_DATA_ORDER| is now of type |const uint8_t *|; previously it was |void *| and all implementations had a |uint8_t *data| variable to access it as an array of bytes. This change paves the way for future refactorings such as automatically generating the |*_Init| functions and/or sharing one I-U-F implementation across all digest algorithms.
