* Deprecate many publically available headersJack Lloyd2019-09-061-0/+2

* Use __builtin_bswapN builtins on XLCJack Lloyd2018-12-311-4/+4
| | | | Recent XLC is based on clang and has these
* Fix generic 32-bit bswapJack Lloyd2018-12-311-2/+6
| | | | Was broken by removing inclusion of rotate header
* Avoid including rotate.h in bswap.hJack Lloyd2018-12-211-2/+1
| | | | | | | It was only needed for one case which is easily hardcoded. Include rotate.h in all the source files that actually use rotr/rotl but implicitly picked it up via loadstor.h -> bswap.h -> rotate.h include chain.
* Use builtin_bswap16 when availableJack Lloyd2018-11-201-0/+4

* Skip ARM32 specific byteswap code, enable MSVC byteswap intrinsicsJack Lloyd2017-10-241-33/+14
| | | | | | | | | | While older versions of GCC did very badly with __builtin_bswap on ARM, I checked GCC 4.8 and it behaves correctly, emitting either rev or else the same optimal sequence as was used in the inline asm (depending on if ARMv7 is enabled or not.) Enable MSVC byteswap intrinsics, which (hopefully) work on all platforms. Drop the x86-32 specific asm for byteswap.
* Add compile-time rotation functionsJack Lloyd2017-10-121-3/+3
| | | | | | | | | | | | | | | | | The problem with asm rol/ror is the compiler can't schedule effectively. But we only need asm in the case when the rotation is variable, so distinguish the two cases. If a compile time constant, then static_assert that the rotation is in the correct range and do the straightforward expression knowing the compiler will probably do the right thing. Otherwise do a tricky expression that both GCC and Clang happen to have recognize. Avoid the reduction case; instead require that the rotation be in range (this reverts 2b37c13dcf). Remove the asm rotations (making this branch illnamed), because now both Clang and GCC will create a roll without any extra help. Remove the reduction/mask by the word size for the variable case. The compiler can't optimize that it out well, but it's easy to ensure it is valid in the callers, especially now that the variable input cases are easy to grep for.
* Remove SSE2 bswap_4Jack Lloyd2017-10-111-24/+0
| | | | | It was disabled anyway (bad macro check) and with recent GCC turned out to be slower than just using bswap.
* Change header guard format to BOTAN_FOO_H_Jack Lloyd2017-09-201-2/+2
| | | | | | ISO C++ reserves names with double underscores in them Closes #512
* Convert to using standard uintN_t integer typesJack Lloyd2016-12-181-8/+8
| | | | | | Renames a couple of functions for somewhat better name consistency, eg make_u32bit becomes make_uint32. The old typedefs remain for now since probably lots of application code uses them.
* Initial support for 64 bit ARMDaniel Seither2015-10-131-2/+2
| | | | | | | | | | | | | | | This adds support for 64 bit ARM cores as used in many high-end phones such as all iPhones beginning with the 5s. While these newer phones still run 32 bit ARM code, Apple doesn't allow apps to be submitted to the app store if they don't provide a 64 bit build. This commit adds a new arm64 arch and renames arm to arm32 to stay consistent with the other architectures. The name arm can still be used for configuring because it has been added as an alias for arm32. Additionally, the one piece of ARM inline assembly that can be found in Botan doesn't work on 64 bit ARM, so I use the solution that has been proposed in #180: Use __builtin_bswap32 instead of inline assembly.
* Avoid 0-defining BOTAN_USE_GCC_INLINE_ASMsimon2015-05-311-3/+3

* Ensure all files have copyright and license info.lloyd2015-01-101-1/+1
| | | | | Update license header line to specify the terms and refer to the file, neither of which it included before.
* Move lib into srclloyd2014-01-101-0/+142
