Compiler implementation of the D programming language.

Members

doptelem elem* doptelem(elem* e, goal_t goal): Optimize and canonicalize an expression tree. Fiddle with double operators so that the rvalue is a pointer (this is needed by the 8086 code generator).
elddtor elem* elddtor(elem* e, goal_t goal): Handle OPddtor
elemisnegone int elemisnegone(elem* e)
elemisone int elemisone(elem* e)
elmsw elem* elmsw(elem* e, goal_t goal): Handle OPmsw.
elpair elem* elpair(elem* e, goal_t goal): Handle OPpair, OPrpair.
elstruct elem* elstruct(elem* e, goal_t goal): See if we can replace struct operations with simpler ones. For OPstreq and OPstrpar.
fillinops
bool fillinops(elem** ops, int* opsi, int maxops, int oper, elem* e): Fill in opsmaxops with operands of repeated operator oper.
postoptelem void postoptelem(elem* e): Do optimizations after bltailrecursion() and before common subexpressions.
swaprel OPER swaprel(OPER op): Swap relational operators (like if we swapped the leaves).
