Document for-loop in tutorial section on loops
Revised Crate section of tutorial for clarity.
Ignore #[phase] on use view items

Closes #11806
Output the correct library filename with --dep-info

Fixes #12174.
Don't use -Z prefer-dynamic at stage0

This is blocking a snapshot because the stage0 target compiler comes from a
stage1 host compiler. This means that the stage0 compiler doesn't actually
understand the -Z prefer-dynamic flag and is dying as a result.

This will get added back to stage0 after a snapshot.
Factoring bigint, rational, and complex out of libextra into libnum.

Removed use of globs present in earlier versions of modules.

Fix tutorial.md to reflect `extra::rational` ==> `num::rational`.
auto merge of #12175 : sfackler/rust/phase-use-ignored, r=alexcrichton

It could throw an error but I think it's best to not since `#[phase(..)]` syntax in other places would be silently ignored.

Closes #11806
auto merge of #12154 : pnkfelix/rust/fsk-factor-bigint-and-rat-out-of-libextra, r=alexcrichton

Removed use of globs present in earlier versions of modules.

Fix tutorial.md to reflect `extra::rational` ==> `num::rational`.
auto merge of #12176 : kballard/rust/dep-info-lib-filename, r=alexcrichton

Fixes #12174.
Correct span for self and ExprStruct
auto merge of #12177 : alexcrichton/rust/fix-snapshot, r=kballard

This is blocking a snapshot because the stage0 target compiler comes from a
stage1 host compiler. This means that the stage0 compiler doesn't actually
understand the -Z prefer-dynamic flag and is dying as a result.

This will get added back to stage0 after a snapshot.
 Explain container iteration in the loop tutorial

 As suggested by @pnkfelix in #12161, this extends the examples by a for-loop
 that iterates over a string as an example for container iteration.
Fix broken link to the container guide
remove dead link to rustpkg documentation
auto merge of #12181 : sanxiyn/rust/accurate-span-4, r=alexcrichton
Tweak test name and make it more specific
Change `xfail` directives in compiletests to `ignore`, closes #11363
auto merge of #12110 : fhahn/rust/issue-11363-change-xfail, r=alexcrichton

Patch for #11363
Add ignore-cross-compile directive for compiletest

Loadable syntax extensions don't work when cross compiling (see #12102), so the
fourcc tests all need to be ignored. They're valuable tests, so they shouldn't
be outright ignored, so they're now flagged with ignore-cross-compile
auto merge of #12171 : chromatic/rust/fix_crate_tutorial_typos, r=brson

This commit attempts to clarify a section of the tutorial. It also fixes some typos.
