I'm working on a build.zig file where I'm leveraging InstallRawStep but I'd like to change the install dir. This allows the install dir to be changd and also enhances InstallRawStep to add more options in the future by putting them into a struct with default values. This also removes the need for an extra addInstallStepWithFormat function in build.zig.
`getExternalExecutor` is moved from `std.zig.CrossTarget` to
`std.zig.system.NativeTargetInfo.getExternalExecutor`.
The function also now communicates a bit more information about *why*
the host is unable to execute a binary. The CLI is updated to report
this information in a useful manner.
`getExternalExecutor` is also improved to detect such patterns as:
* x86_64 is able to execute x86 binaries
* aarch64 is able to execute arm binaries
* etc.
Added qemu-hexagon support to `getExternalExecutor`.
`std.Target.canExecBinaries` of is removed; callers should use the more
powerful `getExternalExecutor` instead.
Now that `zig test` tries to run the resulting binary no matter what,
this commit has a follow-up change to the build system and docgen to
utilize the `getExternalExecutor` function and pass `--test-no-exec`
in some cases to avoid getting the error.
Additionally:
* refactor: extract NativePaths and NativeTargetInfo into their own
files named after the structs.
* small improvement to langref to reduce the complexity of the `callconv`
expression in a couple examples.
Previously when using `zig run` or `zig test`, zig would try to guess
whether the host system was capable of running the target binaries. Now,
it will always try. If it fails, then Zig emits a helpful warning to
explain the probable cause.
from zig-specific options to generally recognized zig build options that
any project can take advantage of. See the updated usage text for more
details.

Previously there was only `--single-threaded`.
This flag now matches other boolean flags, instead of only being able to
opt in to single-threaded builds, you can now force multi-threaded
builds. Currently this only has the possibility to emit an error
message, but it is a better user experience to understand why one cannot
choose to enable threads in some cases.
This is breaking change to the CLI.

The INVAL error was marked unreachable which prevents handling
of the error at a higher level.
It seems like it should map to BadPathError based on the man page for
rmdir (and an incomplete understanding of DeleteDirError), which says:
```
EINVAL pathname has . as last component.

This also modifies tools/update-linux-headers.zig to remove these same
files for next time to prevent a regression.
closes#10249
I don't think we can guarantee that especially for system dyld
dylibs which can be loaded at any address (perhaps even some
OS preferential low memory address).
Incidentally, this fixes stack trace tests on x86_64 macOS 12.
In order to be linker-independent, when parsing debug info in each
linked OSO, we also create a quick lookup table for symbols defined
within the OSO. We then use this lookup to map symbol from the EXE
to its defined address within the original OSO which we can then
use to extract its associated DWARF info (if any).
* Add missing Linux headers. Closes#9837
* Update existing headers to latest Linux.
* Consolidate headers that are the same for multiple Zig target CPU
architectures. For example, Linux has only an x86 directory for both
x86_64 and x86 CPU architectures. Now Zig only ships an x86 directory
for Linux headers, and will emit the proper corresponding -isystem
flags.
* tools/update-linux-headers.zig is now available for upgrading to
newer Linux headers, and the update process is now documented on the
wiki.

- This implements the required codegen for decl types such as pointers, arrays, structs and more.
- Wasm's start function can now use both a 'u8' and 'void' as return type. This will help us with writing tests
using the stage2 testing backend. (Until all tests of behavioural tests pass).
- Now correctly generates relocations for function pointers.
- Also implements unwrapping error union error, as well as return pointers.
- Converts previous `DeclBlock` into `Atom`'s to also make them compatible when
the rest of zlwd gets upstreamed and we can link with other object files.
- Resolves function signatures and removes any duplicates, saving us a lot of
potential bytes for larger projects.
- We now create symbols for each decl of the respective type
- We can now (but not implemented yet) perform proper relocations.
- Having symbols and segment_info allows us to create an object file
for wasm.
