This cleans up how the CLI parses and handles -E, -S, and -c.
Compilation explicitly acknowledges when it is being used to do C
preprocessing.
-S is properly translated to -fno-emit-bin -femit-asm but Compilation
does not yet handle -femit-asm.
There is not yet a mechanism for skipping the linking step when there is
only a single object file, and so to make this work we have to do a file
copy in link.flush() to copy the file from zig-cache into the output
directory.
When upgrading to the new std lib HashMap API, the process_headers code
regressed because something that was supposed to be a pointer ended up
being a copy of a value. This resulted in the modification of a field
not being picked up.
Also switch from Sha256 to Blake3 while we're at it.
Instead of having all primitives and constructions share the same namespace,
they are now organized by category and function family.
Types within the same category are expected to share the exact same API.
In an MSVC context, `-MT` means
"Use static run-time"
and it is a flag with no parameter.
On POSIX it means
"Specify name of main file output in depfile"
and it is "joined or separate".
The former was interfering with the latter. Now, the MT flag is required
to be specified with a `/` to disambiguate: `/MT`.
This caused link errors in c++ code because it was not correct to pass
these flags to child codegens. And that was the only reason to detect
these flags. Otherwise we can safely rely on non-explicitly-detected
flag forwarding.
This is only the first step; it makes zig cc recognize -z and append it to the linker args, but the linker arg parsing doesn't support -z yet so it will just give the warning 'unsupported linker arg: -z'
* The generated options data file is sorted now in a way that
makes sure longer prefixes are first. This prevents collisions
with some parameters.
* Add support for `-fPIC`, `-fno-PIC`, `-nostdlib`, `-shared`,
`-rdynamic`, `-Wl,-soname`, `-Wl,-rpath`
* Better support for `-o`.
* Disable generating h files
* Shared library support.
* Better positional argument support.
This change was mostly made with `zig fmt` and this also modified some whitespace. Note that in some files, `zig fmt` produced incorrect code, so the change was made manually.
* introduce std.json.WriteStream API for writing json
data to a stream
* add WIP tools/merge_anal_dumps.zig for merging multiple semantic
analysis dumps into one. See #3028
* add std.json.Array, improves generated docs
* add test for `std.process.argsAlloc`, improves test coverage and
generated docs
