[Gm2] latest cvs checkins

[Gaius Mulley]

Hi,

just thought I'd relay the latest cvs checkins.  In short the
type COMPLEX is nearly complete - although I see a bug in

testsuite/gm2/complex/run/pass/arith3.mod and arith4.mod

(when evaluating COMPLEX constants).  The new types are
COMPLEX, LONGCOMPLEX, SHORTCOMPLEX (and if the architecture/gcc
runtime supports them COMPLEX32, COMPLEX64, COMPLEX96 and COMPLEX128.
The last four are exported from SYSTEM.  Of course the 32, 64, 96 and
128 refers to the scalar type used within the COMPLEX
structure/record.  The internal functions CMPLX, RE and IM are also
complete - but it is all highly alpha code..


        * gm2/gm2-compiler/M2Base.mod:  IsComplesType includes
          CType.
        * gm2/gm2-compiler/M2GenGCC.mod:  FoldUnary detects
          whether a complex type constant is being used and
          casts it to the CType.

        * gm2/gm2-compiler/M2Base.mod:  extended FindMetaType
          to detect CType constants.  Extended assignment,
          expression and parameter matrices to contain the
          complex family of types.
        * testsuite/gm2/complex/pass/arith.mod and
          testsuite/gm2/complex/pass/arith2.mod new files.

        * gm2/gccgm2.c:  added m2_complex_type_node,
          m2_long_complex_type_node, m2_short_complex_node,
          m2_c_type_node, m2_complex32_type_node,
