* make it always return a fully qualified name. stage1 is inconsistent
about this.
* AstGen: fix anon_name_strategy to correctly be `func` when anon type
creation happens in the operand of the return expression.
* Sema: implement type names for the "function" naming strategy.
* Put "enum", "union", "opaque", or "struct" in place of "anon" when
creating respective anonymous Decl names.
* std.testing: add `expectStringStartsWith`. Didn't end up using it
after all.
Also this enables the real test runner for stage2 LLVM backend (sans
wasm32) since it works now.
I hit the "quotes in an RSP file" issue when trying to compile gRPC using
"zig cc". As a fun exercise, I decided to see if I could fix it myself.
I'm fully open to this code being flat-out rejected. Or I can take feedback
to fix it up.
This modifies (and renames) _ArgIteratorWindows_ in process.zig such that
it works with arbitrary strings (or the contents of an RSP file).
In main.zig, this new _ArgIteratorGeneral_ is used to address the "TODO"
listed in _ClangArgIterator_.
This change closes#4833.
**Pros:**
- It has the nice attribute of handling "RSP file" arguments in the same way it
handles "cmd_line" arguments.
- High Performance, minimal allocations
- Fixed bug in previous _ArgIteratorWindows_, where final trailing backslashes
in a command line were entirely dropped
- Added a test case for the above bug
- Harmonized the _ArgIteratorXxxx._initWithAllocator()_ and _next()_ interface
across Windows/Posix/Wasi (Moved Windows errors to _initWithAllocator()_
rather than _next()_)
- Likely perf benefit on Windows by doing _utf16leToUtf8AllocZ()_ only once
for the entire cmd_line
**Cons:**
- Breaking Change in std library on Windows: Call
_ArgIterator.initWithAllocator()_ instead of _ArgIterator.init()_
- PhaseMage is new with contributions to Zig, might need a lot of hand-holding
- PhaseMage is a Windows person, non-Windows stuff will need to be double-checked
**Testing Done:**
- Wrote a few new test cases in process.zig
- zig.exe build test -Dskip-release (no new failures seen)
- zig cc now builds gRPC without error
* Create Vector language documentation
Main changes to docs:
1. Create brief documentation on Zig vector types with code example
2. Get rid of the SIMD sub-heading under the main Vectors heading,
and update links accordingly
3. Add an example to the `@shuffle` docs
`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.
Updates the Language Reference sections: Comments, Values, and Zig Test.
Zig Test section moved down with the goal "make sure it can be read top to
bottom sensibly" in mind (issue #1524).
Comments and Values section examples changed test declarations to a main
function and expect statement to print statements.
A print statement was added to the "String Literals and Unicode Code Point"
section's example to demonstrate the "u" format specifier.
Zig Test Section:
* Addresses the question: "How does the syntax work?".
* Partially answers the question: "What can I do with the zig test tool?" but
should be sufficient to understand the examples in all of this document.
* Addresses the question: "How does a top-level test block differ from a function definition?"
* Provides a example to run multiple test.
Lacks clear definitions of containers, top-level, order independence, lazy
analysis, resolve, reference.
