Commit 5393e56500d499753dbc39704c0161b47d1e4d5c has a flaw pointed out
by @mlugg: the `ty` field of pointer values changes when comptime values
are pointer-casted. This commit introduces a new encoding which
additionally stores the "original pointer type" which is used to store
the alignment of the anonymous decl, and potentially other information
in the future such as section and pointer address space. However, this
new encoding is only used when the original pointer type differs from
the casted pointer type in a meaningful way.
I was able to make the LLVM backend and the C backend lower anonymous
decls with the appropriate alignment, however I will need some help
figuring out how to do this for the backends that lower anonymous decls
via src/codegen.zig and the wasm backend.
Instead of creating Module.Decl objects, directly create InternPool
pointer values using the anon_decl Addr encoding.
The LLVM backend needed code to notice the alignment of the pointer and
lower accordingly. The other backends likely need a similar change.
* Add missing period in Stack's description
This looks fine in the source, but looks bad when seen on the documentation website.
* Correct documentation for attachSegfaultHandler()
The description for attachSegfaultHandler() looks pretty bad without indicating that the stuff at the end is code
* Added missing 'the's in Queue.put's documentation
* Fixed several errors in Stack's documentation
`push()` and `pop()` were not styled as code
There was no period after `pop()`, which looks bad on the documentation.
* Fix multiple problems in base64.zig
Both "invalid"s in Base64.decoder were not capitalized.
Missing period in documentation of Base64DecoderWithIgnore.calcSizeUpperBound.
* Fix capitalization typos in bit_set.zig
In DynamicBitSetUnmanaged.deinit's and DynamicBitSet.deinit's documentation, "deinitializes" was uncapitalized.
* Fix typos in fifo.zig's documentation
Added a previously missing period to the end of the first line of LinearFifo.writableSlice's documentation.
Added missing periods to both lines of LinearFifo.pump's documentation.
* Fix typos in fmt.bufPrint's documentation
The starts of both lines were not capitalized.
* Fix minor documentation problems in fs/file.zig
Missing periods in documentation for Permissions.setReadOnly, PermissionsWindows.setReadOnly, MetadataUnix.created, MetadataLinux.created, and MetadataWindows.created.
* Fix a glaring typo in enums.zig
* Correct errors in fs.zig
* Fixed documentation problems in hash_map.zig
The added empty line in verify_context's documentation is needed, otherwise autodoc for some reason assumes that the list hasn't been terminated and continues reading off the rest of the documentation as if it were part of the second list item.
* Added lines between consecutive URLs in http.zig
Makes the documentation conform closer to what was intended.
* Fix wrongfully ended sentence in Uri.zig
* Handle wrongly entered comma in valgrind.zig.
* Add missing periods in wasm.zig's documentation
* Fix odd spacing in event/loop.zig
* Add missing period in http/Headers.zig
* Added missing period in io/limited_reader.zig
This isn't in the documentation due to what I guess is a limitation of autodoc, but it's clearly supposed to be. If it was, it would look pretty bad.
* Correct documentation in math/big/int.zig
* Correct formatting in math/big/rational.zig
* Create an actual link to ZIGNOR's paper.
* Fixed grammatical issues in sort/block.zig
This will not show up in the documentation currently.
* Fix typo in hash_map.zig
RSA exponents are typically 3 or 65537, and public.
For those, we don't need to use conditional moves on the exponent,
and precomputing a lookup table is not worth it. So, save a few
cpu cycles and some memory for that common case.
For safety, make `powWithEncodedExponent()` constant-time by default,
and introduce a `powWithEncodedPublicExponent()` function for exponents
that are assumed to be public.
With `powWithEncodedPublicExponent()`, short (<= 36 bits) exponents
will take the fast path.
Previous commit caused this error to be printed:
zig build-exe zig Debug aarch64-macos-none: error: memory usage peaked
at 6323765248 bytes, exceeding the declared upper bound of 5200000000
I observed some out-of-memory conditions happening on one of the CI
servers. This should make it avoid scheduling compiler builds at the
same time as other memory-intensive operations.
Currently, Zig uses the oldest Debian release that is still under LTS
for the default version minimum. This is now Debian 10 (Buster), with
long-term support until 2024-06-30.
Debian Buster uses Linux 4.19 and glibc 2.28.
For the default version maximum, Zig uses the newest stable Linux
version, which is currently 6.5.7.

This reverts commit 78855bd21866b515018259a2194e036e4b3120df.
This commit did not replace uses of `Type.err_int` of which there are
currently 60 uses.
