--debug-rt previously would make rt libs match the root module. Now they
are always debug when --debug-rt is passed. This includes compiler-rt,
fuzzer lib, and others.
with field_ptr_load and field_ptr_named_load.
These avoid doing by-val load operations for structs that are
runtime-known while keeping the previous semantics for comptime-known
values.
When building on macOS Tahoe, binaries were getting duplicate LC_RPATH
load commands which caused dyld to refuse to run them with a
"duplicate LC_RPATH" error that has become a hard error.
The duplicates occurred when library directories were being added
to rpath_list twice:
- from lib_directories
- from native system paths detection which includes the same dirs
I’ve been typing `zig fmt **/.zig` for a long time, until I discovered
that the argument can actually be a directory.
Mention this feature explicitly in the help message.
This bug was manifesting for user as a nasty link error because they
were calling their application's main entry point as a coerced function,
which essentially broke reference tracking for the entire ZCU, causing
exported symbols to silently not get exported.
I've been a little unsure about how coerced functions should interact
with the unit graph before, but the solution is actually really obvious
now: they shouldn't! `Sema` is now responsible for unwrapping
possibly-coerced functions *before* queuing analysis or marking unit
references. This makes the reference graph optimal (there are no
redundant edges representing coerced versions of the same function) and
simplifies logic elsewhere at the expense of just a few lines in Sema.
This instruction actually has fairly useless semantics, and even the
cases that were semantically correct could save 1 cycle of latency by
using a different sequnce involving the avx version instead.

missing `extern` on a struct.
but also all these instances that call pwriteAll with a `@ptrCast` are
endianness bugs.
this should be changed to use File.Writer and call writeSliceEndian
instead.
this commit fixes one immediate problem but does not fix everything.
Before this commit, -Mfoo=bar=baz would be incorrectly split into mod_name: `foo` and root_src_orig: `bar`
After this commit, -Mfoo=bar=baz will be correctly split into mod_name: `foo` and root_src_orig: `bar=baz`
Closes#25059
