`-undefined dynamic_lookup` was added in #13991. `-undefined error` is the
opposite, and can be used to revert an `-undefined dynamic_lookup` flag
specified previously on the command line.
When using llvm opaque pointers, typed pointers and pointer bitcasts are
no longer needed. This also avoids needing packed struct layouts that
are nested inside pointers, letting us avoid computing struct layouts
in Sema that could cause unnecessary dependency loops.
* allow file level `union {}` to parse as tuple field
this was found while fuzzing zls.
* before this patch the input `union {}` crashed the parser. after
this, it parses correctly just like `struct {}`.
* adds behavior tests for both inputs `struct {}` and `union {}`,
checking that each becomes a file level tuple field.
Otherwise, we were prematurely committing `__LINKEDIT` segment LC
with outdated size (i.e., without code signature being taken into account).
This would scaffold into strict validation failures by Apple tooling.
Can occur when trying to open a directory for iteration but the 'List folder contents' permission of the directory is set to 'Deny'.
This was found because it was being triggered during PATH searching in ChildProcess.spawnWindows if a PATH entry did not have 'List folder contents' permission, so this fixes that as well (note: the behavior on hitting this during PATH searching is to treat it as the directory not existing and therefore will fail to find any executables in a directory in the PATH without 'List folder contents' permission; this matches Windows behavior which also fails to find commands in directories that do not have 'List folder contents' permission).
* pthread_key_t should also be available for non-android platforms
* Also change the type to c_uint because Linux pthreadtypes.h typedefs it as "unsigned int"
Partially addresses #13950
The extended instructions starting with opcode `0xFC` are refactored
to make the work the same as the SIMD instructions. This means a
`Mir` instruction no longer contains a field 'secondary'. Instead,
we use the `payload` field to store the index into the extra list
which contains the extended opcode value. In case of instructions
such as 'memory.fill' which also have an immediate value, such
values will also be stored in the extra list right after the
instruction itself. This makes each `Mir` instruction smaller.
These errdefer where never executed, while this didn't bother the stage1
compiler, it caused an error in stage2.
The fix is just removing those errdefer which doesn't change any
behaviour because they were never executed in the first place.
This reverts commit aa3964477f.
This declaration is already provided by operating-system-specific files.
This is not the correct solution to the problem.

these were found while fuzzing zls.
this patch prevents overflow for the following file contents and adds
tests for them.
* `enum(u32)` - causes overflow in std.zig.Ast.fullContainerDecl()
* `*x` - causes overflow in std.zig.Ast.fullPtrType()
* `**x` - causes overflow in std.zig.Ast.firstToken()
When reading a document with nested sections, it is not easy to discover
the depth of the current section.
Add support for nested section numbers, from the h2 to the h4 heading,
in the format "lv1. ", "lv1.lv2. ", "lv1.lv2.lv3. ". The "Zig Version"
and "Table of Content" sections are excluded.
The section numbers are implemented in CSS, with the CSS rules declared
inside a @media rule. Currently the @media rule targets all media.
