921 | # TCL/EXPECT WART ALERT |
922 | # Expect does something very strange when it receives a single braced | |
923 | # argument. It splits it along word separators and performs substitutions. | |
924 | # This means that { "[ab]" } is evaluated as "[ab]", but { "\[ab\]" } is | |
925 | # evaluated as "\[ab\]". But that's not how TCL normally works; inside a | |
926 | # double-quoted list item, "\[ab\]" is just a long way of representing | |
927 | # "[ab]", because the backslashes will be removed by lindex. | |
928 | ||
929 | # Unfortunately, there appears to be no easy way to duplicate the splitting | |
930 | # that expect will do from within TCL. And many places make use of the | |
931 | # "\[0-9\]" construct, so we need to support that; and some places make use | |
932 | # of the "[func]" construct, so we need to support that too. In order to | |
933 | # get this right we have to substitute quoted list elements differently | |
934 | # from braced list elements. | |
935 | ||
936 | # We do this roughly the same way that Expect does it. We have to use two | |
937 | # lists, because if we leave unquoted newlines in the argument to uplevel | |
938 | # they'll be treated as command separators, and if we escape newlines | |
939 | # we mangle newlines inside of command blocks. This assumes that the | |
940 | # input doesn't contain a pattern which contains actual embedded newlines | |

3877 | # | |
3878 | # The type can be one of the following: | |
3879 | # | |
3880 | # - object: Compile into an object file. | |
3881 | # - executable: Compile and link into an executable. | |
3882 | # - preprocess: Preprocess the source files. | |
3883 | # - assembly: Generate assembly listing. | |
3884 | # | |
3885 | # The following options are understood and processed by gdb_compile: | |
3886 | # | |
3887 | # - shlib=so_path: Add SO_PATH to the sources, and enable some target-specific | |
3888 | # quirks to be able to use shared libraries. | |
3889 | # - shlib_load: Link with appropriate libraries to allow the test to | |
3890 | # dynamically load libraries at runtime. For example, on Linux, this adds | |
3891 | # -ldl so that the test can use dlopen. | |
3892 | # - nowarnings: Inhibit all compiler warnings. | |
968aa7ae | 3893 | # - pie: Force creation of PIE executables. |
6e8b1ab2 | 3894 | # - nopie: Prevent creation of PIE executables. |
aff9c0f8 SM |
3895 | # |
3896 | # And here are some of the not too obscure options understood by DejaGnu that | |
3897 | # influence the compilation: | |
3898 | # | |
3899 | # - additional_flags=flag: Add FLAG to the compiler flags. | |
3900 | # - libs=library: Add LIBRARY to the libraries passed to the linker. The | |
3901 | # argument can be a file, in which case it's added to the sources, or a | |
3902 | # linker flag. | |
3903 | # - ldflags=flag: Add FLAG to the linker flags. | |
3904 | # - incdir=path: Add PATH to the searched include directories. | |
3905 | # - libdir=path: Add PATH to the linker searched directories. | |
331733cd PA |
3906 | # - ada, c++, f77, f90, go, rust: Compile the file as Ada, C++, |
3907 | # Fortran 77, Fortran 90, Go or Rust. | |
aff9c0f8 SM |
3908 | # - debug: Build with debug information. |
