Nice work but please hold the horses concerning math/f32/f64. I have a patch for this ready that just awaits pcwalton's review/acceptance of my last pull request and does add a few other things. Concerning min/max: there are generic variants of that in core::float, no need to add them per type. |

In case you are interested, the relevant upcoming patch is https://github.com/boggle/rust/tree/kmath Need a new snapshot before I can test and submit it properly. |
This parallels nicely with string_reader and string_writer, but working with raw byte strings. I'm not quite sure if the return type for bytes_writer.get_bytes should be [u8] or [mutable u8] though, so I'm arbitrarily picking mutable for now.

Thanks Boggle. I stripped out the math/f32/f64 changes. I'll wait for the rest until after your branch gets merged in. |

…<try> Bump bootstrap cc to 1.2.14 and cmake to 0.1.54 ## Summary Bump bootstrap's `cc` and `cmake` deps: 1. To make it easier to add new/unofficial targets. In particular, `cc` v1.2.4+ allows using env vars to pass target parameters to the `cc` crate. This was previously attempted in rust-lang#134344 but ran into macos-cross-to-iOS problems with `cmake` (and also rust-lang#136440, rust-lang#136720). See also discussions in rust-lang/cc-rs#1317. 2. Fix some flag inheritance warnings. Fixes rust-lang#136338. ## `cc` changelogs between `1.2.0` and `1.2.14` > ## [1.2.14](rust-lang/cc-rs@cc-v1.2.13...cc-v1.2.14) - 2025-02-14 > > ### Other > > - Regenerate target info ([rust-lang#1398](rust-lang/cc-rs#1398)) > - Add support for setting `-gdwarf-{version}` based on RUSTFLAGS ([rust-lang#1395](rust-lang/cc-rs#1395)) > - Add support for alternative network stack io-sock on QNX 7.1 aarch64 and x86_64 ([rust-lang#1312](rust-lang/cc-rs#1312)) > > ## [1.2.13](rust-lang/cc-rs@cc-v1.2.12...cc-v1.2.13) - 2025-02-08 > > ### Other > > - Fix cross-compiling for Apple platforms ([rust-lang#1389](rust-lang/cc-rs#1389)) > > ## [1.2.12](rust-lang/cc-rs@cc-v1.2.11...cc-v1.2.12) - 2025-02-04 > > ### Other > > - Split impl Build ([rust-lang#1382](rust-lang/cc-rs#1382)) > - Don't specify both `-target` and `-mtargetos=` on Apple targets ([rust-lang#1384](rust-lang/cc-rs#1384)) > > ## [1.2.11](rust-lang/cc-rs@cc-v1.2.10...cc-v1.2.11) - 2025-01-31 > > ### Other > > - Fix more flag inheritance ([rust-lang#1380](rust-lang/cc-rs#1380)) > - Include wrapper args. in `stdout` family heuristics to restore classifying `clang --driver-mode=cl` as `Msvc { clang_cl: true }` ([rust-lang#1378](rust-lang/cc-rs#1378)) > - Constrain `-Clto` and `-Cembed-bitcode` flag inheritance to be `clang`-only ([rust-lang#1379](rust-lang/cc-rs#1379)) > - Pass deployment target with `-m*-version-min=` ([rust-lang#1339](rust-lang/cc-rs#1339)) > - Regenerate target info ([rust-lang#1376](rust-lang/cc-rs#1376)) > > ## [1.2.10](rust-lang/cc-rs@cc-v1.2.9...cc-v1.2.10) - 2025-01-17 > > ### Other > > - Fix CC_FORCE_DISABLE=0 evaluating to true ([rust-lang#1371](rust-lang/cc-rs#1371)) > - Regenerate target info ([rust-lang#1369](rust-lang/cc-rs#1369)) > - Make hidden lifetimes explicit.

Most patches should be pretty straightforward. The only one I have some question about is 0f1713 (libstd: add bytes_reader and bytes_writer). I'm not quite sure if the return type for get_bytes should be [mutable u8] or [u8]. It's easy enough to convert from one to the other, but most functions seem to return immutable vectors, so I'm not positive my decision to return mutable vectors was the right one or not.
