bors 90442458ac Auto merge of #86048 - nbdd0121:no_floating_point, r=Amanieu ... core: add unstable no_fp_fmt_parse to disable float formatting code In some projects (e.g. kernel), floating point is forbidden. They can disable hardware floating point support and use `+soft-float` to avoid fp instructions from being generated, but as libcore contains the formatting code for `f32` and `f64`, some fp intrinsics are depended. One could define stubs for these intrinsics that just panic [1], but it means that if any formatting functions are accidentally used, mistake can only be caught during the runtime rather than during compile-time or link-time, and they consume a lot of space without LTO. This patch provides an unstable cfg `no_fp_fmt_parse` to disable these. A panicking stub is still provided for the `Debug` implementation (unfortunately) because there are some SIMD types that use `#[derive(Debug)]`.
