[lldb-dev] Using LLDB API on windows

[Russell Greene via lldb-dev]

Interesting:


PS C:\Users\IEUser> C:\msys64\mingw64\bin\lldb.exe
C:\msys64\home\IEUser\chigraph\build\bin\chi.exe
(lldb) target create
"C:\\msys64\\home\\IEUser\\chigraph\\build\\bin\\chi.exe"
Current executable set to
'C:\msys64\home\IEUser\chigraph\build\bin\chi.exe' (x86_64).
(lldb) target list
Current targets:
* target #0: C:\msys64\home\IEUser\chigraph\build\bin\chi.exe (
arch=x86_64-pc-windows-msvc, platform=host )
(lldb)
