K/N debugger on Windows

[msink]

Now Kotlin/Natve works in CLion EAP on Windows, so - what should be used as debugger?

• gdb from msys2-mingw works only for breakpoints and primitive types inspections,
• llvm from msys2-mingw does not work:

C:\msys64\mingw64\bin\lldb.exe: unknown option -- interpreter=mi2
error: unknown or ambiguous option

Process finished with exit code 0

and anyway it is useless:

(lldb) script
error: your copy of LLDB does not support scripting.

Currently, debugging story on Windows is not yet ready, but we plan to support that eventually.

Well, now lldb-1-windows is available on current master, so I can try debugging.
Lets try as steps from DEBUGGING.md:

msink@Sinkovsky MINGW64 /f/src/kotlin-native
$ /f/work/.konan/dependencies/lldb-1-windows/bin/lldb main.exe
(lldb) target create "main.exe"
Current executable set to 'main.exe' (x86_64).
b main.kt:5
(lldb) b main.kt:5
Breakpoint 1: where = main.exe`kfun:main() + 269 at main.kt:5:13, address = 0x000000000042be8d
r
(lldb) r
Process 10928 launched: 'F:\src\kotlin-native\main.exe' (x86_64)
Process 10928 stopped
* thread #1, stop reason = breakpoint 1.1
    frame #0: 0x000000000042be8d main.exe`kfun:main() at main.kt:5:13
   2        var x = 1
   3        var y = 2
   4        var p = Point(x, y)
-> 5        println("p = $p")
                    ^
   6    }
   7    data class Point(val x: Int, val y: Int)
(lldb) fr var
(lldb) fr var
(int) x = 1
(int) y = 2
(ObjHeader *) p = 0x0000000000395978
command script import dist/tools/konan_lldb.py
(lldb) command script import dist/tools/konan_lldb.py
fr var
(lldb) fr var
(int) x = 1
(int) y = 2
(ObjHeader *) p = {}
p p
(lldb) p p
(ObjHeader *) $4 = {}

Something wrong here, should be:

(ObjHeader *) p = Point(x=1, y=2)

According to migrating issue tracking to YouTrack, closing this issue in favour of KT-45987 basic lldb scenario doesn't work on Windows
