The include directories used when preprocessing .rc files are now separate from the target, and by default will use the system MSVC include paths if the MSVC + Windows SDK are present, otherwise it will fall back to the MinGW includes distributed with Zig. This default behavior can be overridden by the `-rcincludes` option (possible values: any (the default), msvc, gnu, or none).
This behavior is useful because Windows resource files may `#include` files that only exist with in the MSVC include dirs (e.g. in `<MSVC install directory>/atlmfc/include` which can contain other .rc files, images, icons, cursors, etc). So, by defaulting to the `any` behavior (MSVC if present, MinGW fallback), users will by default get behavior that is most-likely-to-work.
It also should be okay that the include directories used when compiling .rc files differ from the include directories used when compiling the main binary, since the .res format is not dependent on anything ABI-related. The only relevant differences would be things like `#define` constants being different values in the MinGW headers vs the MSVC headers, but any such differences would likely be a MinGW bug.
Regressed in 2006add8496c47804ee3b6c562f420871cb4ea0a.
References to native_darwin_sdk are no longer kept in the frontend.
Instead the darwin SDK is detected as part of NativePaths and as part of
LibCInstallation.
This can be null in two cases right now:
1. Windows DLLs that zig ships such as advapi32.
2. extern "foo" fn declarations where we find out about libraries too late
TODO: make this non-optional and resolve those two cases somehow.
search_strategy is no longer passed to Compilation at all; instead it is
used in the CLI code only.
When using Zig CLI mode, `-l` no longer has the ability to link
statically; use positional arguments for this.
The CLI has a small abstraction around library resolution handling which
is used to remove some code duplication regarding static libraries, as
well as handle the difference between zig cc CLI mode and zig CLI mode.
Thanks to this, system libraries are now included in the cache hash, and
thus changes to them will correctly cause cache misses.
In the future, lib_dirs should no longer be passed to Compilation at
all, because it is a frontend-only concept.
Previously, -search_paths_first and -search_dylibs_first were
Darwin-only arguments; they now work the same for all targets. Same
thing with --sysroot.
Improved the error reporting for failure to find a system library. An
example error now looks like this:
```
$ zig build-exe test.zig -lfoo -L. -L/a -target x86_64-macos --sysroot /home/andy/local
error: unable to find Dynamic system library 'foo' using strategy 'no_fallback'. search paths:
./libfoo.tbd
./libfoo.dylib
./libfoo.so

/home/andy/local/a/libfoo.dylib
/home/andy/local/a/libfoo.so
/a/libfoo.tbd

Specifically this is to make sure llvm data layout generation doesn't
regress. The no emit bin is to allow testing targets that can't
currently be linked. The commented out targets are ones that fail in
the linker anyway when no emit bin is passed.
6e4fff6ba62ae3e61a948c98fa8fea7e35732cc0 regressed the direct CLI
interface of -femit-docs.
This commit fixes it and also hooks up to the progress bar.
* build.zig: introduce `-Dflat` option which makes the installation
match what we want to ship for our download tarballs. This allows
deleting a bunch of shell script logic from the CI.
- for example it puts the executable directly in prefix/zig rather
than prefix/bin/zig and it additionally includes prefix/LICENSE.
* build.zig: by default also install std lib documentation to doc/std/
- this can be disabled by `-Dno-autodocs` similar to how there is
already `-Dno-langref`.
* build.zig: add `std-docs` and `langref` steps which build and install
the std lib autodocs and langref to prefix/doc/std and
prefix/doc/langref.html, respectively.
* std.Build: implement proper handling of `-femit-docs` using the
LazyPath system. This is a breaking change.
- this is a partial implementation of #16351
* frontend: fixed the handling of Autodocs with regards to caching and
putting the artifacts in the proper location to integrate with the
build system.
- closes#15864
* CI: delete the logic for autodocs since it is now handled by build.zig
and is enabled by default.
- in the future we should strive to have nearly all the CI shell
script logic deleted in favor of `zig build` commands.
* CI: pass `-DZIG_NO_LIB=ON`/`-Dno-lib` except for the one command where
we want to actually generate the langref and autodocs. Generating the
langref takes 14 minutes right now (why?!) so we don't want to do that
more times than necessary.
* Autodoc: fixed use of a global variable. It works fine as a local
variable instead.
- note that in the future we will want to make Autodoc run
simultaneously using the job system, but for now the principle of
YAGNI dictates that we don't have an init()/deinit() API and instead
simply call the function that does the things.
* Autodoc: only do it when there are no compile errors
This is consistent with what clang and gcc are doing, because
headers such as <cet.h> are specifically designed to be used
in the context of assembly code.
Fixes#16449
The idea here is to move towards a future where anonymous decls are
represented entirely by an `InternPool.Index`. This was needed to start
implementing `InternPool.getFuncDecl` which requires moving creation and
deletion of Decl objects into InternPool.
* remove `Namespace.anon_decls`
* remove the concept of cleaning up resources from anonymous decls,
relying on InternPool instead.
* move namespace and decl object allocation into InternPool
Abridged summary:
* Move `Module.Fn` into `InternPool`.
* Delete a lot of confusing and problematic `Sema` logic related to
generic function calls.
This commit removes `Module.Fn` and replaces it with two new
`InternPool.Tag` values:
* `func_decl` - corresponding to a function declared in the source
code. This one contains line/column numbers, zir_body_inst, etc.
* `func_instance` - one for each monomorphization of a generic
function. Contains a reference to the `func_decl` from whence the
instantiation came, along with the `comptime` parameter values (or
types in the case of `anytype`)
Since `InternPool` provides deduplication on these values, these fields
are now deleted from `Module`:
* `monomorphed_func_keys`
* `monomorphed_funcs`
* `align_stack_fns`
Instead of these, Sema logic for generic function instantiation now
unconditionally evaluates the function prototype expression for every
generic callsite. This is technically required in order for type
coercions to work. The previous code had some dubious, probably wrong
hacks to make things work, such as `hashUncoerced`. I'm not 100% sure
how we were able to eliminate that function and still pass all the
behavior tests, but I'm pretty sure things were still broken without
doing type coercion for every generic function call argument.
After the function prototype is evaluated, it produces a deduplicated
`func_instance` `InternPool.Index` which can then be used for the
generic function call.
Some other nice things made by this simplification are the removal of
`comptime_args_fn_inst` and `preallocated_new_func` from `Sema`, and the
messy logic associated with them.
I have not yet been able to measure the perf of this against master
branch. On one hand, it reduces memory usage and pointer chasing of the
most heavily used `InternPool` Tag - function bodies - but on the other
hand, it does evaluate function prototype expressions more than before.
We will soon find out.
When targeting WebAssembly, we default to building a single-threaded build
as threads are still experimental. The user however can enable a multi-
threaded build by specifying '-fno-single-threaded'. It's a compile-error
to enable this flag, but not also enable shared-memory.
When the user enabled the linker-feature 'shared-memory' we do not force
a singlethreaded build. The linker already verifies all other CPU features
required for threads are enabled. This is true for both WASI and
freestanding.
This flag allows the user to force export the memory to the host
environment. This is useful when the memory is imported from the
host but must also be exported. This is (currently) required
to pass the memory validation for runtimes when using threads.
In this future this may become an error instead.
.res files are compiled Windows resource files that get linked into executables/libraries. The linker knows what to do with them, but previously you had to trick Zig into thinking it was an object file (by renaming it to have the .obj extension, for example).
After this commit, the following works:
zig build-exe main.zig resource.res
or, in build.zig:
exe.addObjectFile("resource.res");
Closes#6488
Most of this migration was performed automatically with `zig fmt`. There
were a few exceptions which I had to manually fix:
* `@alignCast` and `@addrSpaceCast` cannot be automatically rewritten
* `@truncate`'s fixup is incorrect for vectors
* Test cases are not formatted, and their error locations change
