Currently -freference-trace only works when running from a terminal.
This is annoying if you're running in another environment or if you redirect the output.
But -freference-trace also works fine without the color, so change how the build runner is interpreting this option.
This allocator has no purpose since it cannot truly fulfill the role of
page allocation, and std.heap.wasm_allocator is better both in terms of
performance and code size.
This commit redefines `std.heap.page_allocator` to be less strict:
"On operating systems that support memory mapping, this allocator makes
a syscall directly for every allocation and free. Otherwise, it falls
back to the preferred singleton for the target. Thread-safe."
This now matches how it was actually being implemented, and matches its
use sites - which are mainly as the backing allocator for
`std.heap.ArenaAllocator`.
These are system DLLs, most of which MinGW provides .def files for. It just so
happens that MinGW also has some static libraries by the same name which link in
some GUID definitions.
The remaining non-MinGW library names represent libraries that are always
statically linked, so if those are requested by the user, it makes sense to
error if libc is not linked. A future enhancement could be to compile those
independent of mingw32.lib, however.
Closes#22560.
I recently saw a user hit the "comptime call of extern function" error,
and get confused because they didn't know why the scope was `comptime`.
So, use `explainWhyBlockIsComptime` on this and related errors to add
all the relevant notes.
The added test case shows the motivating situation.
Turns out this was already fixed in #21964.
I have no idea why GitHub showed an incorrect diff in #21273, or how applying the diff to master was even possible, but here we are.
* `std.builtin.Panic` -> `std.builtin.panic`, because it is a namespace.
* `root.Panic` -> `root.panic` for the same reason. There are type
checks so that we still allow the legacy `pub fn panic` strategy in
the 0.14.0 release.
* `std.debug.SimplePanic` -> `std.debug.simple_panic`, same reason.
* `std.debug.NoPanic` -> `std.debug.no_panic`, same reason.
* `std.debug.FormattedPanic` is now a function `std.debug.FullPanic`
which takes as input a `panicFn` and returns a namespace with all the
panic functions. This handles the incredibly common case of just
wanting to override how the message is printed, whilst keeping nice
formatted panics.
* Remove `std.builtin.panic.messages`; now, every safety panic has its
own function. This reduces binary bloat, as calls to these functions
no longer need to prepare any arguments (aside from the error return
trace).
* Remove some legacy declarations, since a zig1.wasm update has
happened. Most of these were related to the panic handler, but a quick
grep for "zig1" brought up a couple more results too.
Also, add some missing type checks to Sema.
Resolves: #22584
formatted -> full
When using the self-hosted backends, especially in incremental mode, the
.eh_frame_hdr section may be incomplete, so we can't treat it as authoritative.
Instead, if we started out intending to use .eh_frame_hdr but find that it's
incomplete, load .eh_frame/.debug_frame on demand and use that info going
forward.
This will mainly be used when targeting our wasm2c implementation which has no
problem with zero-length bulk memory operations, as a non-standard extension.
