There can be a maximum of 256 compact encodings per page in compact
unwind info, and we were using `u8` to represent the count which is insufficient.
This commit bumps it to `u9`.
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.
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
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
Several enhancements to the build system. Many breaking changes to the API.
* combine `std.build` and `std.build.Builder` into `std.Build`
* eliminate `setTarget` and `setBuildMode`; use an options struct for `b.addExecutable` and friends
* implement passing options to dependency packages. closes#14285
* rename `LibExeObjStep` to `CompileStep`
* move src.type.CType to std lib, use it from std.Build, this helps with populating config.h files.
