Fixes#13970.
This fix makes test runners resolve package paths relative to the
directory the test runner is in. This means it is not possible to import
a file from outside the file tree root at the directory containing the
test runner.
Breaking API change to std.Build.addConfigHeader. It now uses an options
struct.
Introduce std.Build.CompileStep.installConfigHeader which also accepts
an options struct. This is used to add a generated config file into the
set of installed header files for a particular compilation artifact.
std.Build.ConfigHeaderStep now additionally supports a "blank" style
where a header is generated from scratch. It no longer exposes
`output_dir`. Instead it exposes a FileSource via `output_file`.
It now additionally accepts an `include_path` option which affects the
include path of CompileStep when using the `#include` directive, as well
as affecting the default installation subdirectory for header
installation purposes.
The hash used for the directory to store the generated config file now
includes the contents of the generated file. This fixes possible race
conditions when generating multiple header files simultaneously.
The values hash table is now an array hash map, to preserve order for
the "blank" use case.
I also took the opportunity to remove output_dir from TranslateCStep and
WriteFileStep. This is technically a breaking change, but it was always
naughty to access these fields.
Add ability to generate a c header file from scratch, and then both
compile with it and install it if needed.
Example:
```zig
const avconfig_h = b.addConfigHeader(.{ .path = "libavutil/avconfig.h" }, .generated, .{
.AV_HAVE_BIGENDIAN = 0, // TODO: detect based on target
.AV_HAVE_FAST_UNALIGNED = 1, // TODO: detect based on target
});
lib.addConfigHeader(avconfig_h);
lib.installConfigHeader(avconfig_h);
```
Commit 40f5e5dfc6 ("CLI: introduce -fsingle-threaded/
-fno-single-threaded", 2021-12-01) removed the `--single-threaded`
option, but didn't update all mentions of it.
$ zig version
0.11.0-dev.1568+c9b957c93
$ zig build-exe --help | grep single
-fsingle-threaded Code assumes there is only one thread
-fno-single-threaded Code may not assume there is only one thread
$ zig build-exe --single-threaded foo.zig
error: unrecognized parameter: '--single-threaded'
assumeSentinel was removed and replaced with a compileError, but it's
not pub, so the error message indicates it's private rather than
providing the compileError message.
- In Integer Bit Operations, use zeros consistently and fix the
incorrect function descriptions
- In ucmp, fix the incorrect signedness of the operands
- In Integer Arithmetic, document the signedness of the operands in
div, udiv, mod, umod, udivmod and divmod as it is done in LLVM
documentation
- In Float Conversion, replace "int_to_float" to "int to float" and
"uint_to_float" to "uint to float"
New API introduced: std.Build.addModule
This function exposes a zig module with the given name, which can be
used by packages that depend on this one via std.Build.Dependency.module.
std.Build.Pkg and related functionality is deleted. Every use case has a
straightforward upgrade path using the new Module struct.
std.Build.OptionsStep.getPackage is replaced by
std.Build.OptionsStep.createModule.
std.Build.CompileStep.addPackagePath is replaced by
std.Build.CompileStep.addAnonymousModule.
This partially addresses #14307 by renaming some of the instances of
"package" to "module".
Closes#14278
Underlying fix should have been d7b029995c.
u128 limb sizes are still not fully tested as we are missing compiler-rt
support (__divei4, __modei4 on x86_64). Should be no zig blockers so the
assertion has been removed.
This finishes the work started in #14502 where atoms are owned by the
linker themselves. This now makes debug atoms fully owned by dwarf,
and no information is left stored on the decl.
* improve error message when build manifest file is missing
* update std.zig.Ast to support ZON
* Compilation.AllErrors.Message: make the notes field a const slice
* move build manifest parsing logic into src/Manifest.zig and add more
checks, and make the checks integrate into the standard error
reporting code so that reported errors look sexy
closes#14290
* std.zig.parse is moved to std.zig.Ast.parse
* the new function has an additional parameter that requires passing
Mode.zig or Mode.zon
* moved parser.zig code to Parse.zig
* added parseZon function next to parseRoot function
This commit makes the text more dense with sources, noes the outstanding
audit and adds an explanation of the table before converting everything
to markdown tables.
For the status a checkmark or cross in utf8 encoding are used and the
input and output sizes of all operations are given inclusive comments for
understanding of the routines.
This should document all compiler_rt integer and float routines, but
does not include a documentation of existing ieee floating and math
routines.
this patch is from upstream, to fix -Wdeprecated-non-prototypes issues.
K&R-style has apparently been deprecated since even C89, and C2x will be
repurposing the syntax space. this warning triggers when the change would
affect the meaning of the code.
Unfortunately, due to the Windows equivalent of executable permissions
being a bit tricky, there is follow-up work to be done.
What is done in this commit is the hash modifications. At the fetch
layer, executable bits inside packages are ignored. In the hash
computation layer, executable bit is implemented for POSIX but not yet
for Windows. This means that the hash will not break again in the future
for packages that do not have any executable files, but it will break
for packages that do.
This is a hash-breaking change.
Closes#14308
PR #10610 addressed most of the points from #1854. This
additional paragraph and examples covers the OMISSIONS section
clarifying issues about indexing into non-ASCII strings (whether valid
UTF-8 or not). I think this finally closes#1854.
