this isn't actually calloc - it calls the malloc wrapper which no
longer zeroes

it doesn't actually call calloc, so it's fairly pointless

Issue rust-lang#4524

Rename const_view to const_slice
Renamed mut_view to mut_slice

…=catamorphism

This is a natural extension of rust-lang#4887, and handles the following three cases:

a line with only /s
////////////////////////////////////////////

a line with only /s followed by whitespace
////////////////////////////////////////////         

a block comment with only *s between two /s

I removed the unused wrappers methods named `calloc` because they relied on the malloc wrapper having a `bool zero = true` default parameter (which resulted in some accidental zeroing). Perhaps wrapping the actual calloc function would be useful, but I don't know of an existing use case that could use it so I just removed these.

This gives an ~1% performance improvement for TreeMap, which does a lot of small allocations. Vectors use `realloc` which didn't zero before these changes so there's no measurable change in performance.

…amorphism

Removed hacky dependency on Round trait and generic infinity functions
Removed generic-runtime-failure-depending-on-type behavior

Updated the rustc manpage based on the usage message for 0.6 (including -Z options). Also added an example showing how to compile with debug info.

This targets incoming rather than master. rust-lang#4936 can be closed.

Needs a snapshot to remove stage0 extfmt export in core

…sing space-separated ones. rs=plussing

Rid libsyntax of records and get rid of the last piece in `librustc/front/test.rs`.

…r=catamorphism

Previously an unimplemented error was thrown when using #[deriving_eq] on tuple-like struct definitions.

…tpkg.

compiles-as-is, but needs a snapshot to remove the `stage0`ed extfmt export in core.

Closes rust-lang#4750

Now only `lib core/pipes.rs` has `#[allow(structural_records)]`. That can be removed after a snapshot.

…ion-depth-limit, r=catamorphism

It appears that using deriving_eq/auto_encode on ASTs bumps up against the "gee this looks like infinite unfolding" limit of 10 in monomorphization. Increasing it to 30 seems to solve this problem for me....

Also, commenting and a few renames.

Local testing shows it's correctly putting things like ~(@10) in the managed heap. Not entirely sure how to turn such tests (which just log annihilation stats) into a regression test; we don't have much in the way of feedback from the annihilator. Open to suggestions. I will want to be keeping more detailed runtime stats on the gc as I proceed.

With the exception of three places where explicit self ran into borrowing errors. Will try those again once borrowing is refined.
