Functions
Name | Description |
---|---|
doptelem(e, 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(e, goal)
|
Handle OPddtor |
elemisnegone(e)
|
|
elemisone(e)
|
|
elmsw(e, goal)
|
Handle OPmsw. |
elpair(e, goal)
|
Handle OPpair, OPrpair. |
elstruct(e, goal)
|
See if we can replace struct operations with simpler ones. For OPstreq and OPstrpar. |
postoptelem(e)
|
Do optimizations after bltailrecursion() and before common subexpressions. |
swaprel(op)
|
Swap relational operators (like if we swapped the leaves). |
