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

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

| # dejagnu target_compile says that it supports output redirection, |
