Functions

Name	Description
`cdabs(cg, cdb, e, pretregs)`	Absolute value operator, OPabs
`cdbswap(cg, cdb, e, pretregs)`	Bswap operator
`cdcom(cg, cdb, e, pretregs)`	Complement operator
`cdcomma(cg, cdb, e, pretregs)`	Comma operator OPcomma
`cdcond(cg, cdb, e, pretregs)`	?: operator
`cdctor(cg, cdb, e, pretregs)`	C++ constructor.
`cddctor(cg, cdb, e, pretregs)`	D constructor. OPdctor
`cdddtor(cg, cdb, e, pretregs)`	D destructor. OPddtor
`cddiv(cg, cdb, e, pretregs)`	Handle divide, modulo and remquo. Note that modulo isn't defined for doubles.
`cddtor(cg, cdb, e, pretregs)`	OPdtor
`cdhalt(cg, cdb, e, pretregs)`
`cdind(cg, cdb, e, pretregs)`	Perform a 'star' reference (indirection).
`cdloglog(cg, cdb, e, pretregs)`	Do && and \|\| operators.
`cdmemcmp(cg, cdb, e, pretregs)`	Generate code for memcmp(s1,s2,n) intrinsic.
`cdmemcpy(cg, cdb, e, pretregs)`	Generate code for memcpy(s1,s2,n) intrinsic. OPmemcpy / \ s1 OPparam / \ s2 n
`cdmemset(cg, cdb, e, pretregs)`	Generate code for memset(s,value,numbytes) intrinsic. (s OPmemset (numbytes OPparam value))
`cdmul(cg, cdb, e, pretregs)`	Handle multiply.
`cdneg(cg, cdb, e, pretregs)`	OPneg, OPsqrt, OPsin, OPcos, OPrint
`cdnot(cg, cdb, e, pretregs)`	Handle OPnot and OPbool.
`cdorth(cg, cdb, e, pretregs)`	Handle operators which are more or less orthogonal ( + - & \| ^ )
`cdpost(cg, cdb, e, pretregs)`	Post increment and post decrement.
`cdrelconst(cg, cdb, e, pretregs)`	Get the address of. Is also called by cdstreq() to set up pointer to a structure.
`cdshift(cg, cdb, e, pretregs)`	Generate code for shift left or shift right (OPshl,OPshr,OPashr,OProl,OPror).
`cdstrcmp(cg, cdb, e, pretregs)`	Generate code for strcmp(s1,s2) intrinsic.
`cdstrcpy(cg, cdb, e, pretregs)`	Generate code for strcpy(s1,s2) intrinsic.
`cdstreq(cg, cdb, e, pretregs)`	Do structure assignments. This should be fixed so that (s1 = s2) is rewritten to (&s1 = &s2). Mebbe call cdstreq() for double assignments???
`cdstrlen(cg, cdb, e, pretregs)`	Generate code for intrinsic strlen().
`cdvoid(cg, cdb, e, pretregs)`
`getoffset(cg, cdb, e, reg)`	Load the offset portion of the address represented by e into reg.
`idxregm(c)`	Determine index registers used by addressing mode. Index is rm of modregrm field.
`movOnly(e)`
`opdouble(cdb, e, pretregs, clib)`	Gen code for call to floating point routine.
