* Add list of included headers into the manifest
* Implement importing "foreign" type declarations
* Implement forward declarations more natively in the compiler
* Represent Objective-C categories as Kotlin extension methods and
properties
Also:
* Do some refactoring in stub generation
* Call bridges directly in stubs for Objective-C properties
This patch takes into account a corner case available for loops
over a progression (see backend.native/tests/external/codegen/box/
ranges/forInUntil/forInUntilMinint.kt test):
for (i in 0 until Int.MIN_VALUE) { ... }
Here we cannot use subtraction to obtain a right bound of the loop
due to an overflow. Instead we consider any loop with MIN_VALUE in
it's right bound as empty loop. Such behaviour is similar to the one
of 'until' method.
So now the empty check for a loops with 'until' call:
for (i in first until bound) { ... }
is as follows:
val last = getProgressionLast(first, bound, step) // Only if step==1
if (first <= last && bound > <Int|Long|Char>.MIN_VALUE) {
do { ... } while(i != last)
}
Further improvements: We can generate a simpler IR for some simple
frequent cases (e.g. for until calls without steps) and eliminate
loops if we can prove that they are empty.
This patch optimizes the following pattern:
for (i in first..last step st) { ... }
In this case we need to create a Progression object and then call its
iterator() method causing at least 2 allocation per loop. This change
replaces such loops with the following constuction:
var inductionVar = first
checkProgressionStep(step) // check if step > 0
last = getProgressionLastElement(first, last, step)
if (first <= last) {
do {
i = inductionVar
inductionVar += step
...
} while(i != last)
}
The problem was observed in the follwing code:
enum class A(one: Int, val two: Int = one) ...
The problem is in the `two` default value. Here the enum constructor
lowering used an old (not lowered) symbol for `one`. Also the lowering
didn't copy the default expression for DEFAULT class.
The patch fixes both problems.
- Smaller gradle scripts.
- More structure in sample projects.
- Simplified build/run.
- Added gradle to the rest two samples.
- Almost removed all sh scripts.
- Gradle now works only inside of build directory.
- Fixed READMEs according to the new changes.
