Tests that only reference decls for the purpose of analyzing more tests
should be unnamed, otherwise trying to filter for just a referenced test
can become impossible depending on the names.
When a big.Int.Mutable had more than two limbs, it was possible for
this function to change the `len` field without zeroing limbs in the
active range. These uninitialized limbs would then be used in
`truncate()` and could cause invalid results.
Closes#13571
* 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.
ccf670c made using `return` from within a comptime block in a non-inline
function illegal, since it is a use of runtime control flow in a
comptime block. It is allowed if the function in question is `inline`,
since no actual control flow occurs in this case. A few functions from
std (notably `std.fmt.comptimePrint`) needed to be marked `inline` to
support this change.
This pull request removes the optional allocator argument from functions
`divFloor` and `divTrunc`. As a result, the comments related to accepting an
optional `allocator` are no longer applicable. The support for accepting
an optional allocator was removed in #10017.
- Hold the lock for a shorter amount of time
- Previously, when holding the lock while signaling, the other, resumed
thread could potentially get suspended again immediately because
the mutex was still locked.
- Fix comment
- walk the stack via the method that is aware of unwind info (fixes x86_64 / aarch64 traces)
- enhance the output for frames where the debug info isn't available by printing the module name
DELETE_PENDING can happen when the file is yet to be closed for deletion
or if it never get closed. In that case, DeleteFile should assume the
file deletion is succeeding (no CloseHandle is required as it's a "failure"). In case of `DELETE_PENDING` failure, the file
may still exist. In which case if it's part of `deleteTree`, it will
eventually fail on `error.DirNotEmpty`.
This fixes `.INVAL => unreachable` being triggered by the cache system
on macOS when multiple processes race to create the same compilation.
The problem is that when two processes race to create a file, it
sometimes returns ENOENT even though that error code is nonsensical for
this situation.
Commit 2b0929929d purportedly solved this,
but it did not open the file with write permissions, leading to the
EINVAL panic later on. This commit remedies the situation by introducing
a loop and simply retrying when the ENOENT occurs.
Deleting a read-only file should result in `AccessDenied` (`CANNOT_DELETE`).
Note: This test was observed to fail when the file is closed then reopened
before the change in permission due to the absence of
`FILE_WRITE_ATTRIBUTES` when re-opened. (see #15316).
Using `FILE_DELETE_ON_CLOSE` can silently succeed without reporting any error
on non-empty directory. This commit adds usage of NtSetInformationFile
which will report `DIRECTORY_NOT_EMPTY`.
