94a2972d3f compiletest: Add support for ignoring certain tests under --compare-mode=... 2018-07-26 14:51:36 +02:00

4b2e553dac integrate the edition code. 
As a driveby change, I made `#![feature(nll)]` *always* take
precedence over `-Z borrowck`.  The main effect this had is that it
means tests with `#![feature(nll)]` will ignore uses of `-Z
borrowck=compare`. This affected only one test as far as I can tell,
and I think that test used `-Z borrowck=compare` only as a historical
accident.

1a59dafe11 Bug fix: #![feature(nll)] takes precedence over -Z borrowck=migrate. 
(Includes test illustrating desired behavior; compare its diagnostic
output to that of the file `borrowck-migreate-to-nll.rs`.)

f808405328 Test for -Z borrowck=migrate. 
Note that this test is carefully crafted to *try* to not segfault
during its run.  Howver, it really is representing unsound code that
should be rejected after we manage to remove the AST-borrowck entirely
from the compiler.

91dc3e5b56 Add scary warnings to errors-downgraded-to-warnings in borrowck=migrate. 
Also convert an ICE that became reachable code under borrowck=migrate
into a normally reported error (which is then downgraded to a
warning). This actually has a nice side benefit of providing a
somewhat more useful error message, at least in the particular case of
the example from issue #27282.

97f3d21c64 Issue #51348: lower match so an ident gets a distinct temp *for each* candidate pat. 
This required a bit of plumbing to keep track of candidates. But I
took advantage of the hack session to try to improve the docs for the
relevant structs here.

(I also tried to simplify some of the related code in passing.)

f069a57bb1 rustc: Register crates under their real names 
Whenever we register a crate into the crate store, make sure to use the real
name mentioned in the metadata instead of the name mentioned in the `extern
crate` statement, as the statement can be wrong!

Closes #51796

580f437ff2 ARM: expose rclass and dsp target features 
- `dsp`: the subtarget supports the DSP (saturating arith. and such)
         instructions
- `rclass`: target is a Cortex-R

Both features are useful to support ARM MCUs on `coresimd`.

Note: Cortex-R52 is the first Armv8-R with `neon` support
