776 | # Expect does something very strange when it receives a single braced | |
777 | # argument. It splits it along word separators and performs substitutions. | |
778 | # This means that { "[ab]" } is evaluated as "[ab]", but { "\[ab\]" } is | |
779 | # evaluated as "\[ab\]". But that's not how TCL normally works; inside a | |
780 | # double-quoted list item, "\[ab\]" is just a long way of representing | |
781 | # "[ab]", because the backslashes will be removed by lindex. | |
782 | ||
783 | # Unfortunately, there appears to be no easy way to duplicate the splitting | |
784 | # that expect will do from within TCL. And many places make use of the | |
785 | # "\[0-9\]" construct, so we need to support that; and some places make use | |
786 | # of the "[func]" construct, so we need to support that too. In order to | |
787 | # get this right we have to substitute quoted list elements differently | |
788 | # from braced list elements. | |
789 | ||
790 | # We do this roughly the same way that Expect does it. We have to use two | |
791 | # lists, because if we leave unquoted newlines in the argument to uplevel | |
792 | # they'll be treated as command separators, and if we escape newlines | |
793 | # we mangle newlines inside of command blocks. This assumes that the | |

2141 | # TCL). PROMPT is internally converted to a suitable regexp for matching. | |

2143 | # a) It's more intuitive for callers to pass the plain text form. | |
2144 | # b) We need two forms of the prompt: | |
2145 | # - a regexp to use in output matching, | |
2146 | # - a value to pass to the "set prompt" command. | |
2147 | # c) It's easier to convert the plain text form to its regexp form. | |
2148 | # | |
2149 | # 2) Don't add a trailing space, we do that here. | |

3506 | # parameter and most options are passed directly to it. | |
3507 | # | |
3508 | # The type can be one of the following: | |
3509 | # | |
3510 | # - object: Compile into an object file. | |
3511 | # - executable: Compile and link into an executable. | |
3512 | # - preprocess: Preprocess the source files. | |
3513 | # - assembly: Generate assembly listing. | |
3514 | # | |
3515 | # The following options are understood and processed by gdb_compile: | |
3516 | # | |
3517 | # - shlib=so_path: Add SO_PATH to the sources, and enable some target-specific | |
3518 | # quirks to be able to use shared libraries. | |
3519 | # - shlib_load: Link with appropriate libraries to allow the test to | |
3520 | # dynamically load libraries at runtime. For example, on Linux, this adds | |
3521 | # -ldl so that the test can use dlopen. | |
3522 | # - nowarnings: Inhibit all compiler warnings. | |
968aa7ae | 3523 | # - pie: Force creation of PIE executables. |
6e8b1ab2 | 3524 | # - nopie: Prevent creation of PIE executables. |
aff9c0f8 SM |
3525 | # |
3526 | # And here are some of the not too obscure options understood by DejaGnu that | |
3527 | # influence the compilation: | |
3528 | # | |
3529 | # - additional_flags=flag: Add FLAG to the compiler flags. | |
3530 | # - libs=library: Add LIBRARY to the libraries passed to the linker. The | |
3531 | # argument can be a file, in which case it's added to the sources, or a | |
3532 | # linker flag. | |
3533 | # - ldflags=flag: Add FLAG to the linker flags. | |
3534 | # - incdir=path: Add PATH to the searched include directories. | |
3535 | # - libdir=path: Add PATH to the linker searched directories. | |
3536 | # - ada, c++, f77: Compile the file as Ada, C++ or Fortran. | |
3537 | # - debug: Build with debug information. | |
3538 | # - optimize: Build with optimization. | |

6169 | # impossible to define a quote-stripping macro in C.) | |
