842 | # COMMAND is the command to execute, send to GDB with send_gdb. If | |
843 | # this is the null string no command is sent. | |
2307bd6a DJ |
844 | # MESSAGE is a message to be printed with the built-in failure patterns |
845 | # if one of them matches. If MESSAGE is empty COMMAND will be used. | |
590003dc TV |
846 | # -prompt PROMPT_REGEXP specifies a regexp matching the expected prompt |
847 | # after the command output. If empty, defaults to "$gdb_prompt $". | |
848 | # -lbl specifies that line-by-line matching will be used. | |
2307bd6a DJ |
849 | # EXPECT_ARGUMENTS will be fed to expect in addition to the standard |
850 | # patterns. Pattern elements will be evaluated in the caller's | |
851 | # context; action elements will be executed in the caller's context. | |
852 | # Unlike patterns for gdb_test, these patterns should generally include | |
853 | # the final newline and prompt. | |

873 | # gdb_test_multiple, and contains the value of MESSAGE. You can then | |

985 | # TCL/EXPECT WART ALERT |
986 | # Expect does something very strange when it receives a single braced | |
987 | # argument. It splits it along word separators and performs substitutions. | |
988 | # This means that { "[ab]" } is evaluated as "[ab]", but { "\[ab\]" } is | |
989 | # evaluated as "\[ab\]". But that's not how TCL normally works; inside a | |
990 | # double-quoted list item, "\[ab\]" is just a long way of representing | |
991 | # "[ab]", because the backslashes will be removed by lindex. | |
992 | ||
993 | # Unfortunately, there appears to be no easy way to duplicate the splitting | |
994 | # that expect will do from within TCL. And many places make use of the | |
995 | # "\[0-9\]" construct, so we need to support that; and some places make use | |
996 | # of the "[func]" construct, so we need to support that too. In order to | |
997 | # get this right we have to substitute quoted list elements differently | |
998 | # from braced list elements. | |
999 | ||
1000 | # We do this roughly the same way that Expect does it. We have to use two | |
1001 | # lists, because if we leave unquoted newlines in the argument to uplevel | |
1002 | # they'll be treated as command separators, and if we escape newlines | |
1003 | # we mangle newlines inside of command blocks. This assumes that the | |

4334 | # | |

4336 | # | |
4337 | # - object: Compile into an object file. | |
4338 | # - executable: Compile and link into an executable. | |
4339 | # - preprocess: Preprocess the source files. | |
4340 | # - assembly: Generate assembly listing. | |
4341 | # | |
4342 | # The following options are understood and processed by gdb_compile: | |
4343 | # | |
4344 | # - shlib=so_path: Add SO_PATH to the sources, and enable some target-specific | |
4345 | # quirks to be able to use shared libraries. | |
4346 | # - shlib_load: Link with appropriate libraries to allow the test to | |
4347 | # dynamically load libraries at runtime. For example, on Linux, this adds | |
4348 | # -ldl so that the test can use dlopen. | |
4349 | # - nowarnings: Inhibit all compiler warnings. | |
968aa7ae | 4350 | # - pie: Force creation of PIE executables. |
6e8b1ab2 | 4351 | # - nopie: Prevent creation of PIE executables. |
9be5d742 SM |
4352 | # - macros: Add the required compiler flag to include macro information in |
4353 | # debug information | |
2bb8c72b | 4354 | # - text_segment=addr: Tell the linker to place the text segment at ADDR. |
aff9c0f8 SM |
4355 | # |
4356 | # And here are some of the not too obscure options understood by DejaGnu that | |
4357 | # influence the compilation: | |
4358 | # | |
4359 | # - additional_flags=flag: Add FLAG to the compiler flags. | |
4360 | # - libs=library: Add LIBRARY to the libraries passed to the linker. The | |
4361 | # argument can be a file, in which case it's added to the sources, or a | |
4362 | # linker flag. | |
4363 | # - ldflags=flag: Add FLAG to the linker flags. | |
4364 | # - incdir=path: Add PATH to the searched include directories. | |
4365 | # - libdir=path: Add PATH to the linker searched directories. | |
331733cd PA |
4366 | # - ada, c++, f77, f90, go, rust: Compile the file as Ada, C++, |
4367 | # Fortran 77, Fortran 90, Go or Rust. | |
aff9c0f8 SM |
4368 | # - debug: Build with debug information. |
