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

2490 | # Single Unix Spec v3 says that "-E -o ..." together are not | |
2491 | # specified. And in fact, the native compiler on hp-ux 11 (among | |
2492 | # others) does not work with "-E -o ...". Most targets used to do | |
2493 | # this, and it mostly worked, because it works with gcc. | |
2494 | # | |
2495 | # [ catch "exec $compiler -E $ifile > $binfile.ci" exec_output ] | |
2496 | # source $binfile.ci | |
2497 | # | |
2498 | # This avoids the problem with -E and -o together. This almost works | |
2499 | # if the build machine is the same as the host machine, which is | |
2500 | # usually true of the targets which are not gcc. But this code does | |
2501 | # not figure which compiler to call, and it always ends up using the C | |
2502 | # compiler. Not good for setting hp_aCC_compiler. Targets | |
2503 | # hppa*-*-hpux* and mips*-*-irix* used to do this. | |

2508 | # dejagnu target_compile says that it supports output redirection, | |
2509 | # but the code is completely different from the normal path and I | |

2517 | # compiler, and TCL captures the output, and I eval the output. | |
2518 | # | |
2519 | # Unfortunately, expect logs the output of the command as it goes by, | |
