Port tests from upstream parser_test.zig:
- "allow empty line before comment at start of block"
- "comptime struct field"
- "break from block"
- "grouped expressions (parentheses)"
- "array types last token"
Fix bugs in parser.c:
- parseBreakLabel: use null_token instead of null_node
- test decl: use null_token for unnamed tests

Port "zig fmt: respect line breaks in struct field value declaration"
test from upstream parser_test.zig.
Implement in parser.c:
- Slice types ([]T, [:s]T) in parseTypeExpr
- Array types ([N]T, [N:s]T) in parseTypeExpr
- Multiline string literals in parsePrimaryTypeExpr
- Add comments explaining why const/volatile/allowzero pointer
modifiers are consumed (not stored in AST; renderer re-derives
them from token positions)

Now it's based on calling fillMore rather than an illegal aliased stream
into the Reader buffer.
This commit also includes a disambiguation block inspired by #25162. If
`StreamTooLong` was added to `RebaseError` then this logic could be
replaced by removing the exit condition from the while loop. That error
code would represent when `buffer` capacity is too small for an
operation, replacing the current use of asserts.
Fix `takeDelimiter` and `takeDelimiterExclusive` tossing too many bytes
(#25132)
Also add/improve test coverage for all delimiter and sentinel methods,
update usages of `takeDelimiterExclusive` to not rely on the fixed bug,
tweak a handful of doc comments, and slightly simplify some logic.
I have not fixed#24950 in this commit because I am a little less
certain about the appropriate solution there.
Resolves: #25132

* File.Writer.seekBy passed wrong offset to setPosAdjustingBuffer.
* File.Writer.sendFile incorrectly used non-logical position.

Previously, the logic in peekDelimiterInclusive (when the delimiter was not found in the existing buffer) used the `n` returned from `r.vtable.stream` as the length of the slice to check, but it's valid for `vtable.stream` implementations to return 0 if they wrote to the buffer instead of `w`. In that scenario, the `indexOfScalarPos` would be given a 0-length slice so it would never be able to find the delimiter.
This commit changes the logic to assume that `r.vtable.stream` can both:
- return 0, and
- modify seek/end (i.e. it's also valid for a `vtable.stream` implementation to rebase)
Also introduces `std.testing.ReaderIndirect` which helps in being able to test against Reader implementations that return 0 from `stream`/`readVec`
Fixes#25428
Before, this had a subtle ordering bug where duplicate
deps that are specified as both lazy and eager in different
parts of the dependency tree end up not getting fetched
depending on the ordering. I modified it to resubmit lazy
deps that were promoted to eager for fetching so that it will
be around for the builds that expect it to be eager downstream
of this.
--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.
Before https://github.com/ziglang/zig/pull/18160, error tracing defaulted to true in ReleaseSafe, but that is no longer the case. These option descriptions were never updating accordingly.
* Add missing functions like ISDIR() or ISREG(). This is required to
build the zig compiler
* Use octal notation for the S_ constants. This is how it is done for
".freebsd" and it is also the notation used by DragonFly in
"sys/stat.h"
* Reorder S_ constants in the same order as ".freebsd" does. Again, this
follows the ordering within "sys/stat.h"
Clang fails to compile the CBE translation of this code ("non-ASM
statement in naked function"). Similar to the implementations of
`restore_rt` on x86 and ARM, when the CBE is in use, this commit employs
alternative inline assembly that avoids using non-immediate input
operands.
Fixes#25209.
On PowerPC, some registers are both inputs to syscalls and clobbered by
them. An example is r0, which initially contains the syscall number, but
may be overwritten during execution of the syscall.
musl and glibc use a `+` (read-write) constraint to indicate this, which
isn't supported in Zig. The current implementation of PowerPC syscalls
in the Zig standard library instead lists these registers as both inputs
and clobbers, but this results in the C backend generating code that is
invalid for at least some C compilers, like GCC, which doesn't support
the specifying the same register as both an input and a clobber.
This PR changes the PowerPC syscall functions to list such registers as
inputs and outputs rather than inputs and clobbers. Thanks to jacobly0
who pointed out that it's possible to have multiple outputs; I had
gotten the wrong idea from the documentation.
