* FileCheck: fix a bug with multiple --check-prefix options. Similar to r194565Daniel Sanders2013-11-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Directives are being ignored, when they occur between a partial-word false match and any match on another prefix. For example, with FOO and BAR prefixes: _FOO FOO: foo BAR: bar FileCheck incorrectly matches: fog bar This happens because FOO falsely matched as a partial word at '_FOO' and was ignored while BAR matched at 'BAR:'. The match of BAR is incorrectly returned as the 'first match' causing the FOO directive to be discarded. Fixed this the same way as r194565 (D2166) did for a similar test case. The partial-word false match should be counted as a match for the purposes of finding the first match of a prefix, but should be returned as a false match using CheckTy::CheckNone so that it isn't treated as a directive.

* FileCheck: fix a bug with multiple --check-prefix options.Alexey Samsonov2013-11-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This fixes a subtle bug in new FileCheck feature added in r194343. When we search for the first satisfying check-prefix, we should actually return the first encounter of some check-prefix as a substring, even if it's not a part of valid check-line. Otherwise "FileCheck --check-prefix=FOO --check-prefix=BAR" with check file: FOO not a vaild check-line FOO: foo BAR: bar incorrectly accepted file: fog bar as it skipped the first two encounters of FOO, matching only BAR: line.

* [tests] Cleanup initialization of test suffixes.Daniel Dunbar2013-08-16
| | | | | | | | | | | | | | | | | - Instead of setting the suffixes in a bunch of places, just set one master list in the top-level config. We now only modify the suffix list in a few suites that have one particular unique suffix (.ml, .mc, .yaml, .td, .py). - Aside from removing the need for a bunch of lit.local.cfg files, this enables 4 tests that were inadvertently being skipped (one in Transforms/BranchFolding, a .s file each in DebugInfo/AArch64 and CodeGen/PowerPC, and one in CodeGen/SI which is now failing and has been XFAILED). - This commit also fixes a bunch of config files to use config.root instead of older copy-pasted code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188513 91177308-0d34-0410-b5e6-96231b3b80d8

* Add new directive called CHECK-LABEL to FileCheck.Stephen Lin2013-07-12
| | | | | | | | | CHECK-LABEL is meant to be used in place on CHECK on lines containing identifiers or other unique labels (they need not actually be labels in the source or output language, though.) This is used to break up the input stream into separate blocks delineated by CHECK-LABEL lines, each of which is checked independently. This greatly improves the accuracy of errors and fix-it hints in many cases, and allows for FileCheck to recover from errors in one block by continuing to subsequent blocks. Some tests will be converted to use this new directive in forthcoming patches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186162 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove SMLoc paired with CHECK-NOT patterns. Not functionality change.Michael Liao2013-04-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Pattern has source location by itself. After adding a trivial method to retrieve it, it's unnecessary to pair a source location for CHECK-NOT patterns. One thing revised after this is the diagnostic info is more accurate by pointing to the start of the CHECK-NOT pattern instead of the end of the CHECK-NOT pattern. E.g. diagnostic message previously looks like <stdin>:1:1: error: CHECK-NOT: string occurred! test ^ test.txt:1:16: note: CHECK-NOT: pattern specified here CHECK-NOT: test ^ is changed to <stdin>:1:1: error: CHECK-NOT: string occurred! test ^ test.txt:1:12: note: CHECK-NOT: pattern specified here CHECK-NOT: test ^ git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180578 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix a bug in FileCheck that wouldn't let define variables as follows:Eli Bendersky2012-12-02
| | | | | | | | | | | | | | | ; CHECK: [[VAR:[a-z]]] The problem was that to find the end of the regex var definition, it was simplistically looking for the next ]] and finding the incorrect one. A better approach is to count nesting of brackets (taking escaping into account). This way the brackets that are part of the regex can be discovered and skipped properly, and the ]] ending is detected in the right place. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169109 91177308-0d34-0410-b5e6-96231b3b80d8
