Now that they are lazy, they need to get analyzed in the correct
context, when requested.
This commit also hooks up std.builtin type values being resolved
properly. This is needed, for example, with the `@export` builtin
function, which occurs in start.zig, for `std.builtin.ExportOptions`.
The ZIR code uses the special `Ref.export_options` value, and semantic
analysis has to map this to the corresponding type from `std.builtin`.
Functions generated by Fiat-crypto are not prefixed by their description any more. This matches an upstream change.
We can now use a single type for different curves and implementations.
The field type is now generic, so we can properly handle the base field and scalars without code duplication.
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).
AstGen is now completely independent from the rest of the compiler. It
ingests an AST tree and produces ZIR code as the output, without
depending on any of the glue code of the compiler.
In the byteOffset function, compile errors may need to compute the AST
from source bytes in order to resolve source locations. Previously there
were a few lines trying to access the AST before it was loaded. Trivial
fix, just move load the tree at the beginning.
This allows Sema to namespace them separately from function decls with
the same name. Ran into this in std.math.order conflicting with a test
with the same name.
instead of node indexes.
* AstGen: dbg_stmt instructions now have line and column indexes,
relative to the parent declaration. This allows codegen to emit debug
info without having the source bytes, tokens, or AST nodes loaded
in memory.
* ZIR: each decl has the absolute line number. This allows computing
line numbers from offsets without consulting source code bytes.
Memory management: creating a function definition does not prematurely
set the Decl arena. Instead the function is allocated with the general
purpose allocator.
Codegen no longer looks at source code bytes for any reason. They can
remain unloaded from disk.
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.

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.
* AstGen: LocalVal and LocalPtr use string table indexes for their
names. This is more efficient because local variable declarations do
need to include the variable names so that semantic analysis can emit
a compile error if a declaration is shadowed. So we take advantage of
this fact by comparing string table indexes when resolving names.
* The arg ZIR instructions are needed for the above reasoning, as well
as to emit equivalent AIR instructions for debug info.
Now that we have these arg instructions, get rid of the special
`Zir.Inst.Ref` range for parameters. ZIR instructions now refer
to the arg instructions for parameters.
* Move identAsString and strLitAsString from Module.GenZir to AstGen
where they belong.
