the assert_eq! macro compares its arguments and fails if they're not
equal. It's more informative than fail_unless!, because it explicitly
writes the given and expected arguments on failure.
Refactor the self-info so that the def-id is carried in ty_self()and the fn_ctxt doesn't need any self_info field at all. Pull out explicit self transformation into `check_method`. Step towards fixing `fn(&self)` to have a distinct lifetime. (cc #4846)
r? @catamorphism
Removes a lot of instances of `/*bad*/ copy` throughout libsyntax/librustc. On the plus side, this shaves about 2s off of the runtime when compiling `librustc` with optimizations.
Ideally I would have run a profiler to figure out which copies are the most critical to remove, but in reality there was a liberal amount of `git grep`s along with some spot checking and removing the easy ones.
Partial Fix for #5265
- Enabling LLVM ARM ehabi option.
- Add ARM debug information manually for ccall.s
- Compile object file using Android-NDK.
Current LLVM trunk version can generate ARM debug information for assembly files but it is incomplete for object files. Unwinding on ARM can be done with LLVM trunk(the LLVM submodule of rust has problem on generating ARM debug information). See #5368
The Android-NDK detour(0f89eab) can be removed after LLVM has complete feature of generating ARM debug information for object file.
This would close#2761. I figured that if you're supplying your own custom message, you probably don't mind the stringification of the condition to not be in the message.
My goal is to explain the underlying concepts first (destructors and then ownership) with plenty of step-by-step examples, so that thoroughly explaining the semantics of mutability, boxes, moves, etc. is a breeze. I'm trying to avoid the comparisons with C++ that were done before, because this should be approachable for people coming from any language. C++ programmers already know these concepts so they aren't the audience that needs to be catered to. Comparisons with other languages can be done in separate documents (like [this one](https://github.com/mozilla/rust/wiki/Rust-for-CXX-programmers)).
This still needs examples for ownership (inherited mutability), owned boxes and managed boxes.
So this is a partial fix for #3469. Partial because it only works for simple constant expressions like `32/2` and `2+2` and not for any actual constants.
For example:
```
const FOO: uint = 2+2;
let v: [int * FOO];
```
results in:
```
error: expected constant expr for vector length: Non-constant path in constant expr
```
This seems to be because at the point of error (`typeck::astconv`) the def_map doesn't contain the constant and thus it can't lookup the actual expression (`2+2` in this case).
So, feedback on what I have so far and suggestions for how to address the constant issue?
All current meta items types (word, name-value, list) are now
properly parsed by rustc --cfg command line. Fixes#2399
