If set to false, `-nodefaultlibs` is not passed to the linker. This
was the default behavior on Windows, but it should be configurable
per target.
This is a [breaking-change] for target specifications that have
the `is_like_windows` option set to true. Such targets need to
set `no_default_libraries` to false in order to restore the old
behavior.
Since 1.3.0 the BufWriter has seen tremendous speedups. So when I use it in the shootout benchmarks, I see some nice speedup (which up to 1.2.0 was nixed by the pessimizations during initialization).
With -O2, LLVM's inliner can remove this code, but this does not happen
with -O1 and lower. As a result, dropping Vec<u8> was linear with length,
resulting in abysmal performance for large buffers.
See issue #24280.
Move private bignum module to core::num, because it is not only used in flt2dec.
Extract private 80-bit soft-float into new core::num module for the same reason.
This breaks out some of the lints defined in `librustc_lint/builtin.rs` into two new modules: `unused` for the `UNUSED_*` lints and `bad_style` for the various style related lints as suggested in #22206. `builtin.rs` could probably get broken up more but this is a start.
By default, the linker in use under OpenBSD is the linker of base, which
don't include /usr/local/lib where libstdc++ of gcc-4.9 lives. We need
to add this directory to linker-path-search (using -L).
Search the path of libstdc++.a, which is a known name (libstdc++.so has
SO_VERSION) in the same directory.

this commit needs #28495 to be commited first. It should be the last piece for building rustc under OpenBSD from scratch.

This changes how rustic generate `id` and `href` attributes for section header anchor. Now they are more github-like.
Also fixes breakage in docs caused by this and broken links in "Error Handling" section of book.

This reduces some clones of `Vec`s. These are not deep copies since the
token tree is made using `Rc`s, so this won't be a major improvement.
