Use i32 instead of isize for os.timeval's for socket read/write
timeouts.
Add a comptime check to resolveScopeID to see if `IFNAMESIZE` is
available on the host. If it is not available, return an error
indicating that resolving the scope ID of a IPv6 address is not yet
supported on the host platform.
Address comments from @ifreund and @MasterQ32 to address unsafeness and
ergonomics of the `Address` API.
Rename the `TCP` namespace to `tcp` as it does not contain any
top-level fields.
Fix missing reference to `sockaddr` which was identified by @kprotty in
os/bits/linux/arm64.zig.
The `Socket` abstraction was refactored to only comprise of methods that
can be generically used/applied to all socket domains and protocols.
A more comprehensive IPv4/IPv6 module derived from @LemonBoy's earlier
work was implemented under `std.x.os.IPv4` and `std.x.os.IPv6`. Using
this module, one can then combine them together into a union for example
in order to optimize memory usage when dealing with socket addresses.
A `TCP.Client` and `TCP.Listener` abstraction is introduced that is one
layer over the `Socket` abstraction, which isolates methods that can
only be applied to a "client socket" and a "listening socket". All prior
tests from the `Socket` abstraction, which all previously operated
assuming the socket is operating via. TCP/IP, were moved. All TCP socket
options were also moved into the `TCP.Client` and `TCP.Listener`
abstractions respectively away from the `Socket` abstraction.
Some additional socket options from @LemonBoy's prior PR for Darwin were
also moved in (i.e. SIGNOPIPE).
Leave the minimum amount of stack space required by the ABI (16 * 8
bytes for the window contents plus 6 * 8 bytes for the input arguments)
on the new thread stack.
Uses verified code generated by fiat-crypto for field arithmetic, and complete formulas to avoid side channels.
There's still plenty of room for optimizations, especially with a fixed base. But this gives us a framework to easily add other similar curves.
Conflicts:

I had resolved those by removing `comptime` but master branch decided to
make the parameters `comptime`.
This also pulls in the updated default `zig build` install directory.
stage1 did this by accident by unconditionally semantically analyzing
std.builtin.panic, which imports the root source file to look for a
panic handler override. But stage2 is smarter; it will only semantically
analyze std.builtin.panic if any panic calls are emitted. So for very
simple compilations, the root source file was being ignored, even if it
contained `export` functions in it.
* Add a yield pattern for PowerPC64
* Fix compile error on pre-v6 ARM targets
* Use isb instead of yield on AArch64 to give the CPU a chance to enter
low-power states.
* Make the hint an inline function, the call overhead can be avoided.
Currently the default install prefix is $BUILD_ROOT/zig-cache,
but mixing cache and artifacts makes little sense. Instead make
$BUILD_ROOT/zig-out the default.
Should be good enough to unblock progress on the stage2 compiler.
Unifying this parser and the regular one (and perhaps rewrite it, #2207)
is left as an exercise for the reader.
* Remove some unused imports in AstGen.zig. I think it would make sense
to start decoupling AstGen from the rest of the compiler code,
similar to how the tokenizer and parser are decoupled.
* AstGen: For decls, move the block_inline instructions to the top of
the function so that they get lower ZIR instruction indexes. With
this, the block_inline instruction index combined with its corresponding
break_inline instruction index can be used to form a ZIR instruction
range. This is useful for allocating an array to map ZIR instructions
to semantically analyzed instructions.
* Module: extract emit-h functionality into a struct, and only allocate
it when emit-h is activated.
* Module: remove the `decl_table` field. This previously was a table of
all Decls in the entire Module. A "name hash" strategy was used to
find decls within a given namespace, using this global table. Now,
each Namespace has its own map of name to children Decls.
- Additionally, there were 3 places that relied on iterating over
decl_table in order to function:
- C backend and SPIR-V backend. These now have their own decl_table
that they keep populated when `updateDecl` and `removeDecl` are
called.
- emit-h. A `decl_table` field has been added to the new GlobalEmitH
struct which is only allocated when emit-h is activated.
* Module: fix ZIR serialization/deserialization bug in debug mode having
to do with the secret safety tag for untagged unions. There is still an
open TODO to investigate a friendlier solution to this problem with
the language.
* Module: improve deserialization of ZIR to allocate only exactly as
much capacity as length in the instructions array so as to not waste
space.
* Module: move `srcHashEql` to `std.zig` to live next to the definition
of `SrcHash` itself.
* Module: re-introduce the logic for scanning top level declarations
within a namespace.
* Compilation: add an `analyze_pkg` Job which is used to kick off the
start of semantic analysis by doing the equivalent of
`_ = @import("std");`. The `analyze_pkg` job is unconditionally added
to the work queue on every update(), with pkg set to the std lib pkg.
* Rename TZIR to AIR in a few places. A more comprehensive rename will
come later.
* 25519: remove unused const, safeguard against unreduced scalars
No behavior change, but it makes the existing code better match
the forthcoming code for other curves.
Rename nonAdjacentForm() to slide(), remove an unneeded and
confusing constant, and do a reduction in slide() if 257 bits would
be required.
Note that in all the high-level functions, the top bit is always
cleared, so the reduction is never necessary. But since the low-level
functions are public, the check is a safe thing to have.
* 25519: make identityElement public, deprecate neutralElement
Also fix a few comments by the way.
This reverts commit 77cb45f59f.
Zig's error return traces will point to the return token if they
happen to occur, so having multiple return statements makes those
stack traces really helpful. This destroys debuggability.
