The basic approach is that captured vars need to be put on the heap and
that the calling chain needs to be explicitly modelled. Things to consider:
proc a =
var v = 0
proc b =
var w = 2
for x in 0..3:
proc c = capture v, w, x
c()
b()
for x in 0..4:
proc d = capture x
d()
Needs to be translated into:
proc a =
var cl: *
new cl
cl.v = 0
proc b(cl) =
var bcl: *
new bcl
bcl.w = 2
bcl.up = cl
for x in 0..3:
var bcl2: *
new bcl2
bcl2.up = bcl
bcl2.up2 = cl
bcl2.x = x
proc c(cl) = capture cl.up2.v, cl.up.w, cl.x
c(bcl2)
c(bcl)
b(cl)
for x in 0..4:
var acl2: *
new acl2
acl2.x = x
proc d(cl) = capture cl.x
d(acl2)
Closures as interfaces:
proc outer: T =
var captureMe: TObject # value type required for efficiency
proc getter(): int = result = captureMe.x
proc setter(x: int) = captureMe.x = x
result = (getter, setter)
Is translated to:
proc outer: T =
var cl: *
new cl
proc getter(cl): int = result = cl.captureMe.x
proc setter(cl: *, x: int) = cl.captureMe.x = x
result = ((cl, getter), (cl, setter))
For 'byref' capture, the outer proc needs to access the captured var through
the indirection too. For 'bycopy' capture, the outer proc accesses the var
not through the indirection.
Possible optimizations:
Possible optimizations:
1) If the closure contains a single 'ref' and this
reference is not re-assigned (check ``sfAddrTaken`` flag) make this the
closure. This is an important optimization if closures are used as
closure. This is an important optimization if closures are used as
interfaces.
2) If the closure does not escape, put it onto the stack, not on the heap.
3) Dataflow analysis would help to eliminate the 'up' indirections.
