[cfe-dev] clang-cl.exe -fmacro-backtrace-limit=0

[Stephan Bergmann]

It is a bit unfortunate that the clang-cl.exe wrapper can emit 
diagnostics containing "note: (skipping 5 expansions in backtrace; use 
-fmacro-backtrace-limit=0 to see all)" but invoking clang-cl.exe with 
that argument fails hard with "clang-cl.exe: error: unknown argument; 
'-fmacro-backtrace-limit=0'".  But it is not obvious to me what would 
need patching to support that argument in cl mode.
