17.17.4: File Names in DBX Format

This describes file names in DBX format.

DBX_WORKING_DIRECTORY: Define this if DBX wants to have the current directory recorded in each object file.
Note that the working directory is always recorded if GDB extensions are enabled.
DBX_OUTPUT_MAIN_SOURCE_FILENAME (stream, name): A C statement to output DBX debugging information to the stdio stream stream which indicates that file name is the main source file---the file specified as the input file for compilation. This macro is called only once, at the beginning of compilation.
This macro need not be defined if the standard form of output for DBX debugging information is appropriate.
DBX_OUTPUT_MAIN_SOURCE_DIRECTORY (stream, name): A C statement to output DBX debugging information to the stdio stream stream which indicates that the current directory during compilation is named name.
This macro need not be defined if the standard form of output for DBX debugging information is appropriate.
DBX_OUTPUT_MAIN_SOURCE_FILE_END (stream, name): A C statement to output DBX debugging information at the end of compilation of the main source file name.
If you don't define this macro, nothing special is output at the end of compilation, which is correct for most machines.
DBX_OUTPUT_SOURCE_FILENAME (stream, name): A C statement to output DBX debugging information to the stdio stream stream which indicates that file name is the current source file. This output is generated each time input shifts to a different source file as a result of `#include', the end of an included file, or a `#line' command.
This macro need not be defined if the standard form of output for DBX debugging information is appropriate.
