SDK version detection:
- read SDKSettings.json before inferral from SDK path
- vendored libc: add SDKSettings.json for SDK version info
resolveLibSystem:
- adjust search order to { search_dirs, { sysroot or vendored }}
- previous search order was { sysroot, search_dirs, vendored }

This prevents resinator from being included in zig1 and zig2.

Eventually, we will validate DWARF info upfront and report errors
to the user but this will require a rewrite of several parts of
the linker so leaving as a TODO for the near future.

We can infer the framework name from the included resolved framework
path.
Fix hash implementation, and bump linker hash value from 9 to 10.

std.builtin.Mode is deprecated.
|

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

* 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

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.

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.

The main motivation for this commit is eliminating Decl.value_arena.
Everything else is dominoes.
Decl.name used to be stored in the GPA, now it is stored in InternPool.
It ended up being simpler to migrate other strings to be interned as
well, such as struct field names, union field names, and a few others.
This ended up requiring a big diff, sorry about that. But the changes
are pretty nice, we finally start to take advantage of InternPool's
existence.
global_error_set and error_name_list are simplified. Now it is a single
ArrayHashMap(NullTerminatedString, void) and the index is the error tag
value.
Module.tmp_hack_arena is re-introduced (it was removed in
eeff407941560ce8eb5b737b2436dfa93cfd3a0c) in order to deal with
comptime_args, optimized_order, and struct and union fields. After
structs and unions get moved into InternPool properly, tmp_hack_arena
can be deleted again.

`-l :path/to/lib.so` behavior on gcc/clang is:
- the path is recorded as-is: no paths, exact filename (`libX.so.Y`).
- no rpaths.
The previous version removed the `:` and pretended it's a positional
argument to the linker. That works in almost all cases, except in how
rules_go[1] does things (the Bazel wrapper for Go).
Test case in #15743, output:
gcc rpath:
0x0000000000000001 (NEEDED) Shared library: [libversioned.so.2]
0x000000000000001d (RUNPATH) Library runpath: [$ORIGIN/x]
gcc plain:
0x0000000000000001 (NEEDED) Shared library: [libversioned.so.2]
zig cc rpath:
0x0000000000000001 (NEEDED) Shared library: [libversioned.so.2]
0x000000000000001d (RUNPATH) Library runpath: [$ORIGIN/x]
zig cc plain:
0x0000000000000001 (NEEDED) Shared library: [libversioned.so.2]
Fixes #15743

* build.zig: the result of b.option() can be assigned directly in many
cases thanks to the return type being an optional
* std.Build: make the build system aware of the
std.Build.Step.Compile.BuildId type when used as an option.
- remove extraneous newlines in error logs
* simplify caching logic
* simplify hexstring parsing tests and use a doc test
* simplify hashing logic. don't use an optional when the `none` tag
already provides this meaning.
* CLI: fix incorrect linker arg parsing
|

|
|
|
|
* CompileStep: Avoid calling producesPdbFile() to determine whether the
option should be respected. If the user asks for it, put it on the
command line and let the Zig CLI deal with it appropriately.
* Make the namespace of `std.dwarf.Format.dwarf32` no longer have a
redundant "dwarf" in it.
* Add `zig cc` integration for `-gdwarf32` and `-gdwarf64`.
* Toss in a bonus bug fix for `-gdwarf-2`, `-gdwarf-3`, etc.
* Avoid using default init values for struct fields unnecessarily.
* Add missing cache hash addition for the new option.

This commit enables producing 64-bit DWARF format for Zig executables
that are produced through the LLVM backend. This is achieved by exposing
both command-line flags and CompileStep flags. The production of the
64-bit format only affects binaries that use the DWARF format and it is
disabled on MacOS due to it being problematic. This commit, despite
generating the interface for the Zig user to be able to tell the compile
which format is wanted, is just implemented for the LLVM backend, so
clang and the self-hosted backends will need this to be implemented in a
future commit.
This is an effort to work around #7962, since the emission of the 64-bit
format automatically produces 64-bit relocations. Further investigation
will be needed to make DWARF 32-bit format to emit bigger relocations
when needed and not make the linker angry.

* use a set instead of a list
* use of this flag currently requires LLD
* add documentation
* make it only a zig cc compatibility flag for now because I personally
think this is an anti-feature.

We now only update one lazy symbol in flushModule.
Updating the rest from updateDecl is TBD.
|
|
|
|
Also clean up parsing of linker args - reuse `ArgsIterator`.
In MachO, ensure we add every symbol marked with `-u` as undefined
before proceeding with symbol resolution. Additionally, ensure those
symbols are never garbage collected.
MachO entry_in_dylib test: pass `-u _my_main` when linking executable
so that it is not incorrectly garbage collected by the linker.

Ideally, we would just do an atomic rename, but so far I had no
luck. I have also tried marking the file to delete-on-close but
then we cannot use it to spawn the process. So for now, let's just
put a copy in `zig-cache` and let the user decide when to recycle
the cache dir.
