Adds a linker test case for each possible export case. This means
one where no exports are done (i.e. no flags set), when the -dynamic
flag is set, and finally when --export=<value> flag(s) are set.
Adds support for both the `-rdynamic` and the `--export=<value>`
flags. Support is added to both the incremental linker as well as
the traditional linker (zld).
Previously, the implementation would essentially check `startsWith` instead of `eql` (e.g. it would return true for `.exec` because it erroneously 'matched' `.exe`).
Follow up to #13993
In sponge-based constructions, the block size is not the same as
the state size. For practical purposes, it's the same as the rate.
Size this is a constant for a given type, we don't need to keep
a copy of that value in the state itself. Just use the constant
directly. This saves some bytes and may even be slightly faster.
More importantly:
Fixes#14128
Move the parsing of Root from the parse function to the Parser.parseRoot
method.
Add an empty line between each rule, for consistency with grammar.y.
Ensure that normal doc-comments are always on the top, for consistency.
Add extract-grammar.zig to the tools directory; it is used to extract
the PEG grammar from parse.zig, so that it can be compared with
grammar.y.
The HKDF extract function uses HMAC under the hood, but requiring
applications to directly use HMAC functions reduces clarity and
feels like the wrong abstraction.
So, in order to get the PRK length, add a `prk_length` constant
that applications can use directly.
Also add an `extractInit()` function for cases where the keying
material has to be provided as multiple chunks.

LinearFifo is removed from BufferedWriter
Basically, LinearFifo does extra work via copying bytes and increasing
an offset.
This hack was initially introduced as we would export all symbols
unconditionally, including non-function definitions. This would cause
an error from the Wasmtime runtime engine, which this flag would
suppress. As we now properly export symbols, this flag is no longer
needed and any user running into this error can manually include it.
This commit also adds the `--import-symbols` ability to build.zig
When we're compiling compiler_rt for any WebAssembly target, we do
not want to expose all the compiler-rt functions to the host runtime.
By setting the visibility of all exports to `hidden`, we allow the
linker to resolve the symbols during linktime, while not expose the
functions to the host runtime. This also means the linker can
properly garbage collect any compiler-rt function that does not get
resolved. The symbol visibility for all target remains the same as
before: `default`.
No longer automatically append the `--export` flag for each exported
function unconditionally. This was essentially a hack to prevent
binary bloat caused by compiler-rt symbols being always included in
the final binary as they were exported and therefore not garbage-
collected. This is no longer needed as we now support the ability to
set the visibility of exports.

This reverts commit 3370d58956.
This commit was done with an LLVM build that did not have assertions
enabled. There are LLVM assertions being triggered due to this commit.
Reopens#10627Reopens#12013Reopens#12027
This reverts commit 55c3efcb58.
This caused a regression when building Zig with Homebrew.
Also I don't like that it prints a message on success. Only when there
is a problem should an error message be printed.
