Functions like isMinGW() and isGnuLibC() have a good reason to exist: They look
at multiple components of the target. But functions like isWasm(), isDarwin(),
isGnu(), etc only exist to save 4-8 characters. I don't think this is a good
enough reason to keep them, especially given that:
* It's not immediately obvious to a reader whether target.isDarwin() means the
same thing as target.os.tag.isDarwin() precisely because isMinGW() and similar
functions *do* look at multiple components.
* It's not clear where we would draw the line. The logical conclusion before
this commit would be to also wrap Arch.isX86(), Os.Tag.isSolarish(),
Abi.isOpenHarmony(), etc... this obviously quickly gets out of hand.
* It's nice to just have a single correct way of doing something.
these tasks have some shared data dependencies so they cannot be done
simultaneously. Future work should untangle these data dependencies so
that more can be done in parallel.
for now this commit ensures correctness by making linker input parsing
and codegen tasks part of the same queue.
It is now composed of these main sections:
* Declarations that are shared among all operating systems.
* Declarations that have the same name, but different type signatures
depending on the operating system. Often multiple operating systems
share the same type signatures however.
* Declarations that are specific to a single operating system.
- These are imported one per line so you can see where they come from,
protected by a comptime block to prevent accessing the wrong one.
Closes#19352 by changing the convention to making types `void` and
functions `{}`, so that it becomes possible to update `@hasDecl` sites
to use `@TypeOf(f) != void` or `T != void`. Happily, this ended up
removing some duplicate logic and update some bitrotted feature
detection checks.
A handful of types have been modified to gain namespacing and type
safety. This is a breaking change.
Oh, and the last usage of `usingnamespace` site is eliminated.
Instead of calling the dynamically loaded kernel32.GetLastError, we can extract it from the TEB.
As shown by [Wine](34b1606019/include/winternl.h (L439)), the last error lives at offset 0x34 of the TEB in 32-bit Windows and at offset 0x68 in 64-bit Windows.
This function accepts a WaitGroup parameter and manages the reference
counting therein. It also is infallible.
The existing `spawn` function is still handy when the job wants to
further schedule more tasks.
netbsd fix:
- `Futex.zig:542:56: error: expected error union type, found 'c_int'`
openbsd fix:
- `emutls.zig:10:21: error: root struct of file 'os' has no member named 'abort'`
- `Thread.zig:627:22: error: expected 6 argument(s), found 5`
Follow up to #19079, which made test names fully qualified.
This fixes tests that now-redundant information in their test names. For example here's a fully qualified test name before the changes in this commit:
"priority_queue.test.std.PriorityQueue: shrinkAndFree"
and the same test's name after the changes in this commit:
"priority_queue.test.shrinkAndFree"
* Add `timedWait` to `std.Thread.Semaphore`
Add example to documentation of `std.Thread.Semaphore`
* Add unit test for thread semaphore timed wait
Fix missing try
* Change unit test to be simpler
* Change `timedWait()` to keep a deadline
* Change `timedWait()` to return earlier in some scenarios
* Change `timedWait()` to keep a deadline (based on std.Timer)
(similar to std.Thread.Futex)

Free the allocated threads in the initialization of a thread pool only with pool.join instead of additionally calling allocator.free causing free to be called twice.
Resolves#18643
* move std.atomic.Atomic to std.atomic.Value
* fix incorrect argument order passed to testing.expectEqual
* make the functions be a thin wrapper over the atomic builtins and
stick to the naming conventions.
* remove pointless functions loadUnchecked and storeUnchecked. Instead,
name the field `raw` instead of `value` (which is redundant with the
type name).
* simplify the tests by not passing every possible combination. Many
cases were iterating over every possible combinations but then not
even using the for loop element value!
* remove the redundant compile errors which are already implemented by
the language itself.
* remove dead x86 inline assembly. this should be implemented in the
language if at all.
* 128-bit integer multiplication with overflow
* more instruction encodings used by std inline asm
* implement the `try_ptr` air instruction
* follow correct stack frame abi
* enable full panic handler
* enable stack traces
This reverts commit 0c99ba1eab, reversing
changes made to 5f92b070bf.
This caused a CI failure when it landed in master branch due to a
128-bit `@byteSwap` in std.mem.
When a thread is detached from the main thread, we automatically
cleanup any allocated memory. For this we first reset the stack-pointer
to the original stack-pointer of the main-thread so we can safely clear
the memory which also contains the thread's stack.
