Functions

cdvecfill void cdvecfill(CodeBuilder cdb, elem* e, regm_t* pretregs): Generate code for OPvecfill (broadcast). OPvecfill takes the single value in e1 and fills the vector type with it.
cdvecsto void cdvecsto(CodeBuilder cdb, elem* e, regm_t* pretregs): Generate code for vector "store" operations. The tree e must look like: (op1 OPvecsto (op OPparam op2)) where op is the store instruction STOxxxx.
checkSetVex void checkSetVex(code* c, tym_t ty): Determine if operation should be rewritten as a VEX operation; and do so.
checkSetVex3 void checkSetVex3(code* c): VEX prefixes can be 2 or 3 bytes. If it must be 3 bytes, set the CFvex3 flag.
cloadxmm void cloadxmm(CodeBuilder cdb, elem* e, regm_t* pretregs): Load complex operand into XMM registers or flags or both.
isXMMstore bool isXMMstore(opcode_t op): Is operator a store operator?
loadxmmconst bool loadxmmconst(elem* e): Determine if we can load a constant into an XMM register with instructions.
movxmmconst void movxmmconst(CodeBuilder cdb, reg_t xreg, tym_t ty, eve* pev, regm_t flags): Move constant value into xmm register xreg.
orthxmm void orthxmm(CodeBuilder cdb, elem* e, regm_t* pretregs): Do simple orthogonal operators for XMM registers.
xmmIsAligned bool xmmIsAligned(elem* e): Determine if lvalue e is a vector aligned on a 16/32 byte boundary. Assume it to be aligned unless can prove it is not.
xmmabs void xmmabs(CodeBuilder cdb, elem* e, regm_t* pretregs): Absolute value operator OPabs
xmmcnvt void xmmcnvt(CodeBuilder cdb, elem* e, regm_t* pretregs): Generate code for conversion using SSE2 instructions.
xmmeq void xmmeq(CodeBuilder cdb, elem* e, opcode_t op, elem* e1, elem* e2, regm_t* pretregs): Generate code for an assignment using XMM registers.
xmmload opcode_t xmmload(tym_t tym, bool aligned): Get correct load operator based on type. It is important to use the right one even if the number of bits moved is the same, as there are performance consequences for using the wrong one.
xmmneg void xmmneg(CodeBuilder cdb, elem* e, regm_t* pretregs): Negate operator
xmmopass void xmmopass(CodeBuilder cdb, elem* e, regm_t* pretregs): Generate code for op=
xmmpost void xmmpost(CodeBuilder cdb, elem* e, regm_t* pretregs): Generate code for post increment and post decrement.
xmmstore opcode_t xmmstore(tym_t tym, bool aligned): Get correct store operator based on type.
