I got this error when re-running the cmake line setting
-DZIG_EXECUTABLE:
```
ninja: warning: multiple rules generate zig1.o. builds involving
this target will not be correct; continuing anyway
[-w dupbuild=warn]
```
But it works fine with make.
* no longer depend on apt.llvm.org, instead we rely on a zig-bootstrap
tarball with pre-built Zig, LLVM, LLD, and Clang. Similar to the
Windows Dev Kit but for Linux. This also makes the script no longer
depend on Docker, libxml2, or GCC.
* remove bash retry logic; it was only needed for flaky apt.llvm.org
and isn't needed for the other resources we download.
* build and upload the experimental std lib automatically generated
docs. langref.html is moved to docs/langref.html because the std lib
docs are in docs/std/.
* the superfluous "zig" directory in $prefix/lib/zig/std/std.zig is
removed from the tarball.
* update_download_page makes a commit in the www.ziglang.org repository
updating data/releases.json so that repository can manage deploys.
* std.ArrayList gains `moveToUnmanaged` and dead code
`ArrayListUnmanaged.appendWrite` is deleted.
* emit_h state is attached to Module rather than Compilation.
* remove the implementation of emit-h because it did not properly
integrate with incremental compilation. I will re-implement it
in a follow-up commit.
* Compilation: use the .codegen_failure tag rather than
.dependency_failure tag for when `bin_file.updateDecl` fails.
C backend:
* Use a CValue tagged union instead of strings for C values.
* Cleanly separate state into Object and DeclGen:
- Object is present only when generating a .c file
- DeclGen is present for both generating a .c and .h
* Move some functions into their respective Object/DeclGen namespace.
* Forward decls are managed by the incremental compilation frontend; C
backend no longer renders function signatures based on callsites.
For simplicity, all functions always get forward decls.
* Constants are managed by the incremental compilation frontend. C
backend no longer has a "constants" section.
* Participate in incremental compilation. Each Decl gets an ArrayList
for its generated C code and it is updated when the Decl is updated.
During flush(), all these are joined together in the output file.
* The new CValue tagged union is used to clean up using of assigning to
locals without an additional pointer local.
* Fix bug with bitcast of non-pointers making the memcpy destination
immutable.
* CBE buffers are only valid during a flush()
* the file is reopened and truncated during each flush()
* CBE now explicitly ignores updateDecl and deleteDecl
* CBE updateDecl is gone
* test case is enabled
In strictly conforming C, identifiers cannot container dollar signs.
However GCC and Clang allow them by default, so translate-c should
handle them. See http://gcc.gnu.org/onlinedocs/cpp/Tokenization.html
I encountered this in the wild in windows.h
Fixes#7585
This broke build scripts that wanted to refer to `exe_dir` or
`install_path`.
There has also been some pushback and discussion on this breaking
change. I think it should be re-evaluated.
This reverts commit a1a1929cf4ff979bdaba17f858d4ce8647e87a65.
`@setEvalBranchQuota` can be called before the comptime/inline call
stack is created.
For example:
```zig
@setEvalBranchQuota(100);
comptime {
while (true) {}
}
```
Here we need to set the branch_quota before the comptime block creates a
scope for the branch_count.
