* Breaking language change: inline assembly must use string literal
syntax. This is in preparation for inline assembly improvements that
involve more integration with the Zig language. This means we cannot
rely on text substitution.
* Liveness: properly handle inline assembly and function calls with
more than 3 operands.
- More than 35 operands is not yet supported. This is a low priority
to implement.
- This required implementation in codegen.zig as well.
* Liveness: fix bug causing incorrect tomb bits.
* Sema: enable switch expressions that are evaluated at compile-time.
- Runtime switch instructions still need to be reworked in this
branch. There was a TODO left here (by me) with a suggestion to do
some bigger changes as part of the AIR memory reworking. Now that
time has come and I plan to honor the suggestion in a future commit
before merging this branch.
* AIR printing: fix missing ')' on alive instructions.
We're back to "hello world" working for the x86_64 backend.
- deprecates `std.Thread.spinLoopHint` and moves it to `std.atomic.spinLoopHint`
- added an Atomic(T) generic wrapper type which replaces atomic.Bool and atomic.Int
- in Atomic(T), selectively expose member functions depending on T and include bitwise atomic methods when T is an Integer
- added fence() and compilerFence() to std.atomic

Master branch added `try` to a bunch of testing function calls, and some
lines also had changed how to refer to the native architecture and other
`@import("builtin")` stuff.
Beside the new order being consistent with the ThreadPool API and making
more sense, this shuffling allows to write the context argument type in
terms of the startFn arguments, reducing the use of anytype (eg. less
explicit casts when using comptime_int parameters, yay).
Sorry for the breakage.
Closes#8082
* move concurrency primitives that always operate on kernel threads to
the std.Thread namespace
* remove std.SpinLock. Nobody should use this in a non-freestanding
environment; the other primitives are always preferable. In
freestanding, it will be necessary to put custom spin logic in there,
so there are no use cases for a std lib version.
* move some std lib files to the top level fields convention
* add std.Thread.spinLoopHint
* add std.Thread.Condition
* add std.Thread.Semaphore
* new implementation of std.Thread.Mutex for Windows and non-pthreads Linux
* add std.Thread.RwLock
Implementations provided by @kprotty
* std.Mutex API is improved to not have init() deinit(). This API is
designed to support static initialization and does not require any
resource cleanup. This also happens to work around some kind of
stage1 behavior that wasn't letting the new allocator mutex code
get compiled.
* the general purpose allocator now returns a bool from deinit()
which tells if there were any leaks. This value is used by the test
runner to fail the tests if there are any.
* self-hosted compiler is updated to use the general purpose allocator
when not linking against libc.
This change was mostly made with `zig fmt` and this also modified some whitespace. Note that in some files, `zig fmt` produced incorrect code, so the change was made manually.
