2017-04-28Auto merge of #41508 - michaelwoerister:generic-path-remapping, r=alexcrichtonbors-1/+1
Implement a file-path remapping feature in support of debuginfo and reproducible builds This PR adds the `-Zremap-path-prefix-from`/`-Zremap-path-prefix-to` commandline option pair and is a more general implementation of #41419. As opposed to the previous attempt, this implementation should enable reproducible builds regardless of the working directory of the compiler. This implementation of the feature is more general in the sense that the re-mapping will affect *all* paths the compiler emits, including the ones in error messages. r? @alexcrichton

* Use `make check-lexer` to verify the grammar. * Extend grammar/README * Add make clean-grammar rule * Add target `check-build-lexer-verifier` to `make tidy`, so it will build the verifier with every build and catch future errors * Search for antlr4 with configure and find

2015-05-17Revert "Panic if the grammar verifier sees a token it doesn't recognize"Carol Nichols-1/+1
This reverts commit 9c7d5ae57c27ebfc019c2c23283bb905d8c3b74f. This was wrong... the `continue` was to ignore the latter half of the tokens file. Another mechanism will have to be used to keep the model grammar's tokens in sync with the actual grammar's tokens :-/

2015-05-05Panic if the grammar verifier sees a token it doesn't recognizeCarol Nichols-1/+1
To prevent the reference grammar from getting out of sync with the real grammar, panic if RustLexer.tokens contains an unknown token in a similar way that verify.rs panics if it encounters an unknown binary operation token.
2015-05-05Declare other tokens used later in the reference grammarCarol Nichols-3/+3
There were some tokens used in the grammar but not declared. Antlr doesn't really seem to care and happily uses them, but they appear in RustLexer.tokens in a potentially-unexpected order.
2015-05-05Correct a typo in a declared token in the reference grammarCarol Nichols-1/+1
This appears to not have too much of a detrimental effect, but it doesn't seem to be what is intended either. antlr doesn't mind that `PLUS` isn't declared in `tokens` and happily uses the `PLUS` that appears later in the file, but the generated RustLexer.tokens had PLUS at the end rather than where it was intended: NOT=10 TILDE=11 PLUT=12 MINUS=13 ... PLUS=56

2015-02-08Auto merge of #22011 - fhahn:separate-parse-fail-tests, r=nikomatsakisbors-12/+20
This PR moves all `compile-fail` tests that fail at the parsing stage to a `parse-fail` directory, in order to use the tests in the `parse-fail` directory to test if the new LALR parser rejects the same files as the Rust parser. I also adjusted the `testparser.py` script to handle the tests in `parse-fail` differently. However during working on this, I discovered, that Rust's parser sometimes fails during parsing, but does not return a nonzero return code, e.g. compiling `/test/compile-fail/doc-before-semi.rs` with `-Z parse-only` prints an error message, but returns status code 0. Compiling the same file without `-Z parse-only`, the same error message is displayed, but error code 101 returned. I'll look into that over the next week.
