Embrace the Path abstraction, doing more operations based on directory
handles rather than absolute file paths. Most of the diff noise here
comes from this one.
Fix sorting of crtbegin/crtend atoms. Previously it would look at all
path components for those strings.
Make the C runtime path detection partially a pure function, and move
some logic to glibc.zig where it belongs.
This works around the fact that LLVM and LLD both have broken support for the
small data area, yet the feature is on by default for all Hexagon CPUs.
I want to eventually replace this hack with a flag in update_cpu_features.zig
for marking features that should always be off by default and not be accessible
to users. That way, the compiler will have full control over them.
* Added error message 'ProcessNotFound' for reading and writing in a Linux
process.
This error occurs if the process to be read from or written to no longer exists.
Fixes#19875
* Added error message "ProcessNotFound" for error forwarding.
* Add error messgae for forwarding.
* Added message for forwarding.
* Error set completed.
* Fixed format error.
* Changed comments to doc comments.
Abi.android on its own is not enough to know whether soft float or hard float
should be used. In the C world, androideabi is typically used for the soft float
case, so let's go with that.
Note that Android doesn't have a hard float ABI, so no androideabihf.
Closes#21488.

Since we never hooked up the (experimental) DirectX LLVM backend, we've never
actually supported targeting DXIL in Zig. With Microsoft moving away from DXIL,
that seems very unlikely to change.
The previous API used `std.testing.fuzzInput(.{})` however that has the
problem that users call it multiple times incorrectly, and there might
be work happening to obtain the corpus which should not be included in
coverage analysis, and which must not slow down iteration speed.
This commit restructures it so that the main loop lives in libfuzzer and
directly calls the "test one" function.
In this commit I was a little too aggressive because I made the test
runner export `fuzzer_one` for this purpose. This was motivated by
performance, but it causes "exported symbol collision: fuzzer_one" to
occur when more than one fuzz test is provided.
There are three ways to solve this:
1. libfuzzer needs to be passed a function pointer instead. Possible
performance downside.
2. build runner needs to build a different process per fuzz test.
Potentially wasteful and unclear how to isolate them.
3. test runner needs to perform a relocation at runtime to point the
function call to the relevant unit test. Portability issues and
dubious performance gains.

This commit modifies the `multiline_string_literal_line`, `doc_comment`,
and `container_doc_comment` tokens to no longer include the line ending
as part of the token. This makes it easier to handle line endings (which
may be LF, CRLF, or in edge cases possibly nonexistent) consistently.
In the two issues linked above, Autodoc was already assuming this for
doc comments, and yielding incorrect results when handling files with
CRLF line endings (both in Markdown parsing and source rendering).
Applying the same simplification for multiline string literals also
brings `zig fmt` into conformance with
https://github.com/ziglang/zig-spec/issues/38 regarding formatting of
multiline strings with CRLF line endings: the spec says that `zig fmt`
should remove the CR from such line endings, but this was not previously
the case.
The parse of `fn foo(a: switch (...) { ... })` was previously handled
incorrectly; `a` was treated as both the parameter name and a label.
The same issue exists for `for` and `while` expressions -- they should
be fixed too, and the grammar amended appropriately. This commit does
not do this: it only aims to avoid introducing regressions from labeled
switch syntax.
The compiler actually doesn't need any functional changes for this: Sema
does reification based on the tag indices of `std.builtin.Type` already!
So, no zig1.wasm update is necessary.
This change is necessary to disallow name clashes between fields and
decls on a type, which is a prerequisite of #9938.
