* Reorganize crypto/aes in order to separate parameters, implementations and
modes.
* Add a zero-cost abstraction over the internal representation of a block,
so that blocks can be kept in vector registers in optimized implementations.
* Add architecture-independent aesenc/aesdec/aesenclast/aesdeclast operations,
so that any AES-based primitive can be implemented, including these that don't
use the original key schedule (AES-PRF, AEGIS, MeowHash...)
* Add support for parallelization/wide blocks to take advantage of hardware
implementations.
* Align T-tables to cache lines in the software implementations to slightly
reduce side channels.
* Add an optimized implementation for modern Intel CPUs with AES-NI.
* Add new tests (AES256 key expansion).
* Reimplement the counter mode to work with any block cipher, any endianness
and to take advantage of wide blocks.
* Add benchmarks for AES.
Password hashing functions are not general-purpose KDFs, and KDFs
don't have to satisfy the same properties as a PHF.
This will allow fast KDFs such as the HKDF construction to be in a
category of their own, while clarifying what functions are suitable
for using passwords as inputs.
A simple empty main with evented-io would not quit, because some
threads were still waiting to be resumed (by the os). The os.write to
the eventfd only wakes up one thread and thus there are multiple writes
needed to wake up all the other threads.
As part of this:
* add std.process.cleanExit. closes#6395
- use it in several places
* adjust the alignment of text in `zig build --help` menu
* Cache: support the concept of "unhit" so that we properly keep track
of the cache when we find out using the secondary hash that the cache
"hit" was actually a miss. Use this to fix false negatives of caching
of stage1 build artifacts.
* fix not deleting the symlink hash for stage1 build artifacts causing
false positives.
* implement support for Package arguments in stage1 build artifacts
* update and add missing usage text
* add --override-lib-dir and --enable-cache CLI options
- `--enable-cache` takes the place of `--cache on`
* CLI supports -femit-bin=foo combined with --enable-cache to do an
"update file" operation. --enable-cache without that argument
will build the output into a cache directory and then print the path
to stdout (matching master branch behavior).
* errors surfacing from main() now print "error: Foo" instead of
"error: error.Foo".
* add CLI support for verbose debugging options
* implement building compiler_rt and libc static archive using stage1
C++ backend
* add function_sections and link_libcpp to root cache hash.
* cleanups to use the new Directory.join method.
* Package supports being initialized directly and cleaned up create()
method.
* fix classifyFileExt incorrectly saying .zir is .zig. Thanks
@Rocknest!
* unify updateSubCompilation implementations
HeapAllocator stores the pointer returned by HeapAlloc right after the
data block and, after the recent allocator refactoring, the space for
this pointer was not taken into account in the calculation of the final
block size.
Fixes#5830
* move stage2.cpp code into zig0.cpp for simplicity
* add -ftime-report and some more CLI options to stage2
* stage2 compites the llvm cpu features string
* classifyFileExt understands more file extensions
* correction to generateBuiltinZigSource using the wrong allocator
(thanks dbandstra!)
* stage2 is now able to build hello.zig into hello.o using stage1 as a
library however it fails linking due to missing compiler-rt
* remove dead code
* simplify zig0 builtin.zig source
* fix not resolving builtin.zig source path causing duplicate imports
* fix stage1.h not being valid C code
* fix stage2.h not being valid C code
