e05412669c8dde1230612de5af64fbc3fb0bc17e inadvertently changed the logic on Windows and made it so that supportsAnsiEscapeCodes was never checked. This fixes that regression while keeping the logic intact for other platforms.
The panic handler expects that this value is represented with the
generic address space, so cast the global to the generic address-
space before caching and returning the value.
The SPIR-V cannot print the helpful error messages from the
std.testing module. This commit overrides the default print
function used here to one that only prints if the target supports
it. For now, its only done for SPIR-V, but this function could
be adapted to more targets that need it.
This implements the semantics as discussed in today's compiler meeting,
where the alignment of pointers to fields of default-layout unions
cannot exceed the field's alignment.
Resolves: #15878
Previously, interned values were represented as AIR instructions using
the `interned` tag. Now, the AIR ref directly encodes the InternPool
index. The encoding works as follows:
* If the ref matches one of the static values, it corresponds to the same InternPool index.
* Otherwise, if the MSB is 0, the ref corresponds to an InternPool index.
* Otherwise, if the MSB is 1, the ref corresponds to an AIR instruction index (after removing the MSB).
Note that since most static InternPool indices are low values (the
exceptions being `.none` and `.var_args_param_type`), the first rule is
almost a nop.
When targeting WebAssembly, we default to building a single-threaded build
as threads are still experimental. The user however can enable a multi-
threaded build by specifying '-fno-single-threaded'. It's a compile-error
to enable this flag, but not also enable shared-memory.
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.
When `join` detects a thread has completed, it will free the allocated
memory of the thread. For this we must first copy the allocator. This is
required as the allocated memory holds a reference to the original
allocator. If we free the memory, we would end up with UB as the
allocator would free itself.
