Mostly, these are the ones whose body just contains `f(self)`.
2020-02-13Rollup merge of #69050 - nnethercote:micro-optimize-leb128, r=michaelwoeristerDylan DPC-50/+14
Micro-optimize the heck out of LEB128 reading and writing. This commit makes the following writing improvements: - Removes the unnecessary `write_to_vec` function. - Reduces the number of conditions per loop from 2 to 1. - Avoids a mask and a shift on the final byte. And the following reading improvements: - Removes an unnecessary type annotation. - Fixes a dangerous unchecked slice access. Imagine a slice `[0x80]` -- the current code will read past the end of the slice some number of bytes. The bounds check at the end will subsequently trigger, unless something bad (like a crash) happens first. The cost of doing bounds check in the loop body is negligible. - Avoids a mask on the final byte. And the following improvements for both reading and writing: - Changes `for` to `loop` for the loops, avoiding an unnecessary condition on each iteration. This also removes the need for `leb128_size`. All of these changes give significant perf wins, up to 5%. r? @michaelwoerister

2019-12-24Deprecate Error::description for realDavid Tolnay-18/+3
`description` has been documented as soft-deprecated since 1.27.0 (17 months ago). There is no longer any reason to call it or implement it. This commit: - adds #[rustc_deprecated(since = "1.41.0")] to Error::description; - moves description (and cause, which is also deprecated) below the source and backtrace methods in the Error trait; - reduces documentation of description and cause to take up much less vertical real estate in rustdocs, while preserving the example that shows how to render errors without needing to call description; - removes the description function of all *currently unstable* Error impls in the standard library; - marks #[allow(deprecated)] the description function of all *stable* Error impls in the standard library; - replaces miscellaneous uses of description in example code and the compiler.

2019-07-07rustc: Remove `dylib` crate type from most rustc cratesAlex Crichton-1/+0
Now that procedural macros no longer link transitively to libsyntax, this shouldn't be needed any more! This commit is an experiment in removing all dynamic libraries from rustc except for librustc_driver itself. Let's see how far we can get with that!

2019-06-23Fix meta-variable binding errors in macrosJulien Cretin-9/+9
The errors are either: - The meta-variable used in the right-hand side is not bound (or defined) in the left-hand side. - The meta-variable used in the right-hand side does not repeat with the same kleene operator as its binder in the left-hand side. Either it does not repeat enough, or it uses a different operator somewhere. This change should have no semantic impact.

2019-06-10Rollup merge of #59600 - tobia:master, r=pnkfelixMazdak Farrokhzad-5/+12
Replaced linear token counting macros with optimized implementation There are currently two distinct token-counting macros in the source. Both implement the trivial algorithm, with linear complexity. They may or may not be adequate for their use case, but considering that other people are probably going to copy and paste them whenever they need a token-counting macro, I replaced them with an optimized implementation with logarithmic complexity.
