The reason they have been introduced initially was because those indices were calcuated irrelative to the descriptros themselves. The current scheme with hashing the mangled name allows to calcuate the indices for the descriptors, rather than storing them. The measurements didn't reveal any slowdowns because of hash recalculations, rather there may be even a minor improvement because of a 2% smaller volume of module protobuf.
Kotlin/Native
Kotlin/Native is a LLVM backend for the Kotlin compiler, runtime implementation and native code generation facility using LLVM toolchain.
Kotlin/Native is primarily designed to allow compilation for platforms where virtual machines are not desirable or possible (such as iOS, embedded targets), or where developer is willing to produce reasonably-sized self-contained program without need to ship an additional execution runtime.
To compile from sources use following steps.
First download dependencies:
./gradlew dependencies:update
Then build the compiler and standard library:
./gradlew dist
To build standard library for cross-targets (currently, iOS on Mac OSX and Raspberry Pi on Linux hosts) use:
./gradlew cross_dist
After that you should be able to compile your programs like that:
export PATH=./dist/bin:$PATH
kotlinc hello.kt -o hello
For an optimized compilation use -opt:
kotlinc hello.kt -o hello -opt
For some tests, use:
./gradlew backend.native:tests:run
To generate interoperability stubs create library definition file
(take a look on samples/tetris/sdl.def) and run cinterop tool like this:
cinterop -def lib.def
See provided samples and INTEROP.md for more details.
