716 | # Expect does something very strange when it receives a single braced | |
717 | # argument. It splits it along word separators and performs substitutions. | |
718 | # This means that { "[ab]" } is evaluated as "[ab]", but { "\[ab\]" } is | |
719 | # evaluated as "\[ab\]". But that's not how TCL normally works; inside a | |
720 | # double-quoted list item, "\[ab\]" is just a long way of representing | |
721 | # "[ab]", because the backslashes will be removed by lindex. | |
722 | ||
723 | # Unfortunately, there appears to be no easy way to duplicate the splitting | |
724 | # that expect will do from within TCL. And many places make use of the | |
725 | # "\[0-9\]" construct, so we need to support that; and some places make use | |
726 | # of the "[func]" construct, so we need to support that too. In order to | |
727 | # get this right we have to substitute quoted list elements differently | |
728 | # from braced list elements. | |
729 | ||
730 | # We do this roughly the same way that Expect does it. We have to use two | |
731 | # lists, because if we leave unquoted newlines in the argument to uplevel | |
732 | # they'll be treated as command separators, and if we escape newlines | |
733 | # we mangle newlines inside of command blocks. This assumes that the | |

1833 | # underlined substring in | |

1844 | # proc do_tests {} { | |

3288 | # | |
3289 | # - shlib=so_path: Add SO_PATH to the sources, and enable some target-specific | |
3290 | # quirks to be able to use shared libraries. | |
3291 | # - shlib_load: Link with appropriate libraries to allow the test to | |
3292 | # dynamically load libraries at runtime. For example, on Linux, this adds | |
3293 | # -ldl so that the test can use dlopen. | |
3294 | # - nowarnings: Inhibit all compiler warnings. | |

3296 | # And here are some of the not too obscure options understood by DejaGnu that | |
3297 | # influence the compilation: | |
3298 | # | |
3299 | # - additional_flags=flag: Add FLAG to the compiler flags. | |
3300 | # - libs=library: Add LIBRARY to the libraries passed to the linker. The | |
3301 | # argument can be a file, in which case it's added to the sources, or a | |
3302 | # linker flag. | |
3303 | # - ldflags=flag: Add FLAG to the linker flags. | |
3304 | # - incdir=path: Add PATH to the searched include directories. | |
3305 | # - libdir=path: Add PATH to the linker searched directories. | |
3306 | # - ada, c++, f77: Compile the file as Ada, C++ or Fortran. | |
