musl v1.2.4 dropped the "64"-suffixed aliases for legacy "LFS64" ("large
file support") interfaces, so this commit changes the corresponding Zig
logic to call the correct names.
PPC targets can also use the functionality-equivalent standard routine, so
unconditionally export the standard routine.
Fixup of #16054 merged in f043071cdfb956ff16b1441c9d01ce43eea9fb7b.
The assert is changed from `int != 0` to `int > 0` because negative
integers always return `false`.
Python's `math.log2` does the same and errors for 0 or negative integers.
isatty on Windows is implemented as a isCygwinPty call and a GetConsoleMode call, so calling isatty just duplicates the function calls we already need to do in supportsAnsiEscapeCodes.
Make to avoid releasing request's connection twice.
Change the `Request.connection` field optional. This field is null while the connection is released.
Fixes#15965
Adress review comments from https://github.com/ziglang/zig/pull/13977
by using the same naming convention as zstd.
And by using `finish()` instead of `close()` for the finalisation of the compressed stream.
rationale:
- it is not the same as how close() is usually used, since it must be called to flush and write the final bytes. And as such it may fail.
- it is not the same `flush` in the deflate code, which allows to keep writting more bytes later, and doesn't write the final checksum.
- it is the same name as used in the original zlib library (Z_FINISH)
Also, use a packed struct for the header, which seems a better fit.
Anecdote 1: The generic version is way more popular than the non-generic
one in Zig codebase:
git grep -w alignForward | wc -l
56
git grep -w alignForwardGeneric | wc -l
149
git grep -w alignBackward | wc -l
6
git grep -w alignBackwardGeneric | wc -l
15
Anecdote 2: In my project (turbonss) that does much arithmetic and
alignment I exclusively use the Generic functions.
Anecdote 3: we used only the Generic versions in the Macho Man's linker
workshop.
Adds conditional exports
- __fixkfti
- __fixunskfti
- __floattikf
- __negkf2
- __mulkc3
- __divkc3
- __powikf2
and adjusts tools/gen_stubs.zig.
From https://gcc.gnu.org/onlinedocs/gcc/Floating-Types.html:
"When long double transitions to __float128 on PowerPC in the future,
__ibm128 will remain for use in conversions between the two types."
Hence `__extendkftf2` and `__trunctfkf2` for conversion are superfluous
and only using f128 for `kf` routines is justified.
Closes#16057.
Missed this originally because I was only able to trigger it when
SA_RESTART was missing from the sigaction handlers. I'm unconvinced this
is actually a sane way for stdlib to behave (see #15664). But this does
duplicate the existing behavior throughout os.zig which IMO should be
prioritized here.
See https://reviews.llvm.org/D81809 for upstream description.
In summary this is ~10x improvement for small divisors and similar
performance for equal divisors.
Closes#13523.
