2016-05-16Fix `asm!` blocksAndrea Canciani-2/+2
The `volatile` modifier was incorrectly written outside of the `asm!` blocks.
2016-05-16Cleanup documentationAndrea Canciani-31/+10
Remove irrelevant information (and instead provide pointer to reference documentation), replace ASCII-art table with the corresponding MarkDown one, and minor fixes.
2016-05-13Document the x87 control wordAndrea Canciani-5/+62
Explain the meaning of the fields of the control word and provide more details about how the relevant one (Precision Control) is updated in the fast path.
2016-05-13Fix fast path of float parsing on x87Andrea Canciani-7/+40
The fast path of the float parser relies on the rounding to happen exactly and directly to the correct number of bits. On x87, instead, double rounding would occour as the FPU stack defaults to 80 bits of precision. This can be fixed by setting the precision of the FPU stack before performing the int to float conversion. This can be achieved by changing the value of the x87 control word. This is a somewhat common operation that is in fact performed whenever a float needs to be truncated to an integer, but it is undesirable to add its overhead for code that does not rely on x87 for computations (i.e. on non-x86 architectures, or x86 architectures which perform FPU computations on using SSE). Fixes `num::dec2flt::fast_path_correct` (on x87).

2016-05-06Auto merge of #33138 - arielb1:sized-shortcut, r=nikomatsakisbors-1/+1
Short-cut `T: Sized` trait selection for ADTs Basically avoids all nested obligations when checking whether an ADT is sized - this speeds up typeck by ~15% The refactoring fixed #32963, but I also want to make `Copy` not object-safe (will commit that soon). Fixes #33201 r? @nikomatsakis

Implement negation for wrapping numerals. Fixes #33037

2016-05-03require the non-last elements of a tuple to be SizedAriel Ben-Yehuda-1/+1
This requirement appears to be missing from RFC1214, but is clearly necessary for translation. The last field of a tuple/enum remains in a state of limbo, compiling but causing an ICE when it is used - we should eventually fix that somehow. this is a [breaking-change] - a soundness fix - and requires a crater run.

2016-03-12std: Clean out deprecated APIsAlex Crichton-176/+1
Removes all unstable and deprecated APIs prior to the 1.8 release. All APIs that are deprecated in the 1.8 release are sticking around for the rest of this cycle. Some notable changes are: * The `dynamic_lib` module was moved into `rustc_back` as the compiler still relies on a few bits and pieces. * The `DebugTuple` formatter now special-cases an empty struct name with only one field to append a trailing comma.
2016-03-11core: Make a new tracking issue for prelude traitsAlex Crichton-3/+3
The referenced issues here were both closed, so hook up a new issue which tracks specifically the prelude traits being unstable.
2016-03-11core: Mark Wrapping impls as stableAlex Crichton-5/+5
These are all insta-stable anyway, so just properly tag them.
2016-03-08doc: Fix a bunch of broken linksAlex Crichton-3/+3
A few categories: * Links into compiler docs were just all removed as we're not generating compiler docs. * Move up one more level to forcibly go to std docs to fix inlined documentation across the facade crates.
2016-03-01Rollup merge of #31965 - miqid:doc, r=steveklabnikSteve Klabnik-10/+10
Hello. Quite a few of the links in the `core` module concerning redirection to additional primitive type documentation are broken. I noticed in #30214 that there seemed to be a consensus with linking across to `std` module documentation from the `core` module. This is what I've done with the `core` modules for primitive types. If the changes here are good to go forward with, I'll happily tend to adding more documentation links for the extension traits in the aforementioned issue if need be. r? @steveklabnik
2016-03-01Fix broken links for core primitivesMichael Huynh-10/+10
Redirects existing links for more details on primitive types in the `core` module to the ones that exist in the `std` module.

2016-02-26Use .copy_from_slice() where applicableUlrik Sverdrup-2/+2
.copy_from_slice() does the same job of .clone_from_slice(), but the former is explicitly for Copy elements and calls `memcpy` directly, and thus is it efficient without optimization too.

2016-02-04Prevent the immediate panic uncovered by #31109 and add a test.Robin Kruppe-8/+28
The code there still triggers an ICE, but for different reasons (const eval unwraps the parse result).
2016-02-04Use the right target ratio in Algorithm M quickstart.Robin Kruppe-1/+1
Using f64's bit size probably wasn't actually *wrong*, but it would overshoot for no reason. This might have slowed down f32 parsing significantly.

2016-01-14Auto merge of #30466 - alexcrichton:move-wrapping-and-fill-out, r=aturonbors-14/+658
This commit migrates all of the methods on `num::wrapping::OverflowingOps` onto inherent methods of the integer types. This also fills out some missing gaps in the saturating and checked departments such as: * `saturating_mul` * `checked_{neg,rem,shl,shr}` This is done in preparation for stabilization, cc #27755
2016-01-13Auto merge of #30639 - rkruppe:dec2flt-fastpath-tables, r=alexcrichtonbors-9/+59
Add tables of small powers of ten used in the fast path. The tables are redundant: We could also use the big, more accurate table and round the value to the correct type (in fact we did just that before this commit). However, the rounding is extra work and slows down the fast path. Because only very small exponents enter the fast path, the table and thus the space overhead is negligible. Speed-wise, this is a clear win on a [benchmark] comparing the fast path to a naive, hand-optimized, inaccurate algorithm. Specifically, this change narrows the gap from a roughly 5x difference to a roughly 3.4x difference. [benchmark]: https://gist.github.com/Veedrac/dbb0c07994bc7882098e
