676 | # TCL/EXPECT WART ALERT |
677 | # Expect does something very strange when it receives a single braced | |
678 | # argument. It splits it along word separators and performs substitutions. | |
679 | # This means that { "[ab]" } is evaluated as "[ab]", but { "\[ab\]" } is | |
680 | # evaluated as "\[ab\]". But that's not how TCL normally works; inside a | |
681 | # double-quoted list item, "\[ab\]" is just a long way of representing | |
682 | # "[ab]", because the backslashes will be removed by lindex. | |
683 | ||
684 | # Unfortunately, there appears to be no easy way to duplicate the splitting | |
685 | # that expect will do from within TCL. And many places make use of the | |
686 | # "\[0-9\]" construct, so we need to support that; and some places make use | |
687 | # of the "[func]" construct, so we need to support that too. In order to | |
688 | # get this right we have to substitute quoted list elements differently | |
689 | # from braced list elements. | |
690 | ||
691 | # We do this roughly the same way that Expect does it. We have to use two | |
692 | # lists, because if we leave unquoted newlines in the argument to uplevel | |
693 | # they'll be treated as command separators, and if we escape newlines | |
694 | # we mangle newlines inside of command blocks. This assumes that the | |

1665 | # Test files shall make sure all the test result lines in gdb.sum are |

1667 | # test runs gives correct results. Test files that exercise | |

1672 | # About test prefixes: | |
1673 | # | |
1674 | # $pf_prefix is the string that dejagnu prints after the result (FAIL, | |
1675 | # PASS, etc.), and before the test message/name in gdb.sum. E.g., the | |
1676 | # underlined substring in | |
1677 | # | |
1678 | # PASS: gdb.base/mytest.exp: some test | |
1679 | # ^^^^^^^^^^^^^^^^^^^^ | |
1680 | # | |
1681 | # is $pf_prefix. | |
1682 | # | |
1683 | # The easiest way to adjust the test prefix is to append a test | |
1684 | # variation prefix to the $pf_prefix, using the with_test_prefix | |
1685 | # procedure. E.g., | |
1686 | # | |
1687 | # proc do_tests {} { | |
1688 | # gdb_test ... ... "test foo" | |
1689 | # gdb_test ... ... "test bar" | |

2526 | # others) does not work with "-E -o ...". Most targets used to do | |

2533 | # if the build machine is the same as the host machine, which is | |
2534 | # usually true of the targets which are not gcc. But this code does | |
2535 | # not figure which compiler to call, and it always ends up using the C | |
