2018-12-16Rollup merge of #56855 - nikic:remove-cttz-hack, r=nagisaMazdak Farrokhzad-14/+1
Remove u8 cttz hack This issue has since been fixed in LLVM: https://github.com/llvm-mirror/llvm/commit/1886c8e29a9992d73c5e6ba0d52eb98ee036ab5d Furthermore this code doesn't actually work, because the 8 literal does not match the $BITS provided from the macro invocation, so effectively this was just dead code. Ref #43024. What LLVM does is still not ideal for CPUs that only have bsf but not tzcnt, will create a patch for that later. r? @nagisa

Add TryFrom<&[T]> for [T; $N] where T: Copy `TryFrom<&[T]> for &[T; $N]` (note *reference* to an array) already exists, but not needing to dereference makes type inference easier for example when using `u32::from_be_bytes`. Also add doc examples doing just that.

Make `ParseIntError` and `IntErrorKind` fully public Why would you write nice error types if I can't read them? # Why It can be useful to use `match` with errors produced when parsing strings to int. This would be useful for the `.err_match()` function in my [new crate](https://crates.io/crates/read_input). --- I could also do this for `ParseFloatError` if people think it is a good idea. I am new around hear so please tell me if I am getting anything wrong.

2018-11-03Implement rotate using funnel shift on LLVM >= 7Nikita Popov-2/+12
Implement the rotate_left and rotate_right operations using llvm.fshl and llvm.fshr if they are available (LLVM >= 7). Originally I wanted to expose the funnel_shift_left and funnel_shift_right intrinsics and implement rotate_left and rotate_right on top of them. However, emulation of funnel shifts requires emitting a conditional to check for zero shift amount, which is not necessary for rotates. I was uncomfortable doing that here, as I don't want to rely on LLVM to optimize away that conditional (and for variable rotates, I'm not sure it can). We should revisit that question when we raise our minimum version requirement to LLVM 7 and don't need emulation code anymore.
