1 # Library of functions for dealing with DejaGNU, or which are otherwise
2 # generally useful for the DejaGNU tool stack.
3 #
4 # Author: Matthew Sachs <msachs@apple.com>
5 #
6 # Functions:
7 # parseLogFile: See "sub parseLogFile" below for details. This function
8 # returns a detailed parse of a DejaGNU log or sum file.
9 # ispass: Takes a DejaGNU result (e.g. "PASS", "XPASS") and returns
10 # true if and only if it is a passing result (PASS, XFAIL, or
11 # KFAIL.)

68 # Extract information from DejaGNU log or sum files.

70 # gccdir:
71 # Passing in the full path to the root of the gcc/testsuite directory
72 # will help in the parsing, but if it isn't provided, it will be guessed.
73 # diagnostics:
74 # If set to 0, diagnostics will not be returned. This can save a lot
75 # of memory if you are not using this information.
76 # fullname:
77 # If set to 0, the fullname key will not be included in tests.
78 # Returns a hash with the following keys:
79 # incomplete: 1 if the summary file appears truncated, otherwise 0
80 # diagnostics: List of (type, value) for any errors detected. Type can be ERROR, WARNING, or NOTE.
81 # test: Array of root-level tests, with keys:
82 # name: Name of the test, relative to the enclosing test group.
83 # fullname: Fully-qualified name of the test.
84 # result: DejaGNU result (PASS, FAIL, XPASS, &c)
85 # detail: For multi-phase (e.g. compile/link/execute), this will be
86 # the furthest phase which the test was able to attempt,
87 # so if the result is FAIL and this is "link phase", the test
88 # compiled but failed to link. This key may contain other
89 # auxiliary data.
90 # pseudotest: If 1, this test may not really exist; see "pseudotest" below.
91 # testgroup: Array of root-level testgroups, with keys:
92 # name: Name of the group.
93 # parent: Parent test group.
94 # test: As per above.
95 # testgroup: Child test groups.
96 # compiler: Version string from compiler used to run the tests (if detected)
