Module dmd.backend.cod2

Code generation 2


- math operators (+ - * / %) and functions (abs, cos, sqrt) - 'string' functions (strlen, memcpy, memset) - pointers (address of / dereference) - struct assign, constructor, destructor

Compiler implementation of the D programming language.



cdabs(cdb, e, pretregs) Absolute value operator
cdbswap(cdb, e, pretregs) Bswap operator
cdcom(cdb, e, pretregs) Complement operator
cdcomma(cdb, e, pretregs) Comma operator OPcomma
cdcond(cdb, e, pretregs) ?: operator
cdctor(cdb, e, pretregs) C++ constructor.
cddctor(cdb, e, pretregs) D constructor. OPdctor
cdddtor(cdb, e, pretregs) D destructor. OPddtor
cddiv(cdb, e, pretregs) Handle divide, modulo and remquo. Note that modulo isn't defined for doubles.
cddtor(cdb, e, pretregs) OPdtor
cdhalt(cdb, e, pretregs)
cdind(cdb, e, pretregs) Perform a 'star' reference (indirection).
cdloglog(cdb, e, pretregs) Do && and || operators.
cdmemcmp(cdb, e, pretregs) Generate code for memcmp(s1,s2,n) intrinsic.
cdmemcpy(cdb, e, pretregs) Generate code for memcpy(s1,s2,n) intrinsic. OPmemcpy / \ s1 OPparam / \ s2 n
cdmemset(cdb, e, pretregs) Generate code for memset(s,value,numbytes) intrinsic. (s OPmemset (numbytes OPparam value))
cdmul(cdb, e, pretregs) Handle multiply.
cdneg(cdb, e, pretregs) OPneg, OPsqrt, OPsin, OPcos, OPrint
cdnot(cdb, e, pretregs) Handle OPnot and OPbool.
cdorth(cdb, e, pretregs) Handle operators which are more or less orthogonal ( + - & | ^ )
cdpost(cdb, e, pretregs) Post increment and post decrement.
cdrelconst(cdb, e, pretregs) Get the address of. Is also called by cdstreq() to set up pointer to a structure.
cdshift(cdb, e, pretregs) Generate code for shift left or shift right (OPshl,OPshr,OPashr,OProl,OPror).
cdstrcmp(cdb, e, pretregs) Generate code for strcmp(s1,s2) intrinsic.
cdstrcpy(cdb, e, pretregs) Generate code for strcpy(s1,s2) intrinsic.
cdstreq(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(cdb, e, pretregs) Generate code for intrinsic strlen().
cdvoid(cdb, e, pretregs)
getoffset(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.
opdouble(cdb, e, pretregs, clib) Gen code for call to floating point routine.
