567 | # TCL/EXPECT WART ALERT |
568 | # Expect does something very strange when it receives a single braced | |
569 | # argument. It splits it along word separators and performs substitutions. | |
570 | # This means that { "[ab]" } is evaluated as "[ab]", but { "\[ab\]" } is | |
571 | # evaluated as "\[ab\]". But that's not how TCL normally works; inside a | |
572 | # double-quoted list item, "\[ab\]" is just a long way of representing | |
573 | # "[ab]", because the backslashes will be removed by lindex. | |
574 | ||
575 | # Unfortunately, there appears to be no easy way to duplicate the splitting | |
576 | # that expect will do from within TCL. And many places make use of the | |
577 | # "\[0-9\]" construct, so we need to support that; and some places make use | |
578 | # of the "[func]" construct, so we need to support that too. In order to | |
579 | # get this right we have to substitute quoted list elements differently | |
580 | # from braced list elements. | |
581 | ||
582 | # We do this roughly the same way that Expect does it. We have to use two | |
583 | # lists, because if we leave unquoted newlines in the argument to uplevel | |
584 | # they'll be treated as command separators, and if we escape newlines | |
585 | # we mangle newlines inside of command blocks. This assumes that the | |

1368 | # BINFILE is a "compiler information" output file. This implementation | |
1369 | # does not use BINFILE. | |
1370 | # | |
1371 | # ARGS can be empty or "C++". If empty, "C" is assumed. | |
1372 | # | |

1374 | # | |
1375 | # [ gdb_compile -E $ifile -o $binfile.ci ] | |
1376 | # source $binfile.ci | |
1377 | # | |
1378 | # Single Unix Spec v3 says that "-E -o ..." together are not | |
1379 | # specified. And in fact, the native compiler on hp-ux 11 (among | |
1380 | # others) does not work with "-E -o ...". Most targets used to do | |
1381 | # this, and it mostly worked, because it works with gcc. | |
1382 | # | |
1383 | # [ catch "exec $compiler -E $ifile > $binfile.ci" exec_output ] | |
1384 | # source $binfile.ci | |
1385 | # | |
1386 | # This avoids the problem with -E and -o together. This almost works | |
1387 | # if the build machine is the same as the host machine, which is | |
1388 | # usually true of the targets which are not gcc. But this code does | |
1389 | # not figure which compiler to call, and it always ends up using the C | |
1390 | # compiler. Not good for setting hp_aCC_compiler. Targets | |
1391 | # hppa*-*-hpux* and mips*-*-irix* used to do this. | |

1396 | # dejagnu target_compile says that it supports output redirection, | |
1397 | # but the code is completely different from the normal path and I | |

1406 | # | |
1407 | # Unfortunately, expect logs the output of the command as it goes by, | |
