6m(1)                                                       6m(1)

     NAME
          6m

     SYNOPSIS
          6m [ -?hioSG9d ] [ file ... ]

     DESCRIPTION
          The ?m compiler family compiles Myrddin source into object
          files for the corresponding architecture. Each architecture
          gets its own compler. Unless otherwise specified, if the
          input file is named filename.myr then the the object file
          that is generated will be named filename.o.

          Any text between the first '+' in the file name and the suf-
          fix are stripped. This functionality is used to specify sys-
          tem tags for tools like mbld.

          If the filename does not end with the suffix .myr then the
          object suffix .o will simply be appended to it.

          The following architectures are currently supported:

          6m   x86-64

          The compiler options are:

          -h | -?
               Print a summary of the available options.

          -d [flTriu]
               Print debugging dumps. Additional options may be given
               to give more debugging information for specific inter-
               mediate states of the compilation.

          -I path
               Add 'path' to the search path for unquoted use stat-
               ments. This option does not affect the search path for
               local usefiles, which are always searched relative to
               the directory containing the output file. Without any
               options, the search path defaults to /usr/include/myr.

          -o output-file
               Specify that the generated code should be placed in
               output-file instead of the default location.

          -S   Generate assembly code along with the object file.

          -G   Generate assembly in the Gnu As syntax.

          -O out
               Output code to output path 'out'

          -T   Compile in test mode. This implies that pkglocal func-
               tions are available.

          -9   Generate assembly in the Plan 9 syntax.

     EXAMPLE
               6m foo.myr
               6m bar.myr
               ld -o foobar foo.o bar.o

     BUGS
          There are virtually no optimizations done, and the generated
          source is often very poorly performing.

          The current calling convention is stack-based and not
          register-based, even on architectures where it should be
          register-based.

          The calling convention is not compatible with C.
