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 suffix are
       stripped. This functionality is used to specify system tags  for	 tools
       like 'mbld'.

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

       The following architectures are currently supported:

       6m     x86-64

       The compiler options are:

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

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

       -I path
	      Add 'path' to the	search path for	unquoted use  statments.  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	functions  are
	      available.

       -9     Generate assembly	in the Plan 9 syntax.

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

FILES
       The  source  code  for this compiler is available from git://git.eigen-
       state.org/git/ori/mc.git

SEE ALSO
       muse(1) ld(1) as(1)

BUGS
       The language is not yet complete, and the compilers often  omit	useful
       constructs in spite of their desirability.

       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.
