Zig's format system is flexible enough to add custom formatters. This PR removes the new z/Z format specifiers that were added for printing Zig identifiers and replaces them with custom formatters.
This PR ensures we use system libc headers and system search paths for
framework headers when linking against frameworks and compiling natively
on macOS.
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
