[cfe-dev] Clang-cl disable exceptions/rtti and macro issue

Sun May 4 06:26:04 PDT 2014

Hi guys,

I have a couple of problems while trying to compile my program using 
Clang-cl. First issue, even passing /GR- and Xclang -fno-rtti I get:

                         ^
error: cannot mangle RTTI descriptors for type 'bad_cast' yet
error: cannot mangle the name of type 'bad_cast' into RTTI descriptors yet
error: cannot mangle RTTI descriptors for type 'exception' yet
error: cannot mangle the name of type 'exception' into RTTI descriptors yet
error: cannot mangle RTTI descriptors for type 'bad_cast' yet
error: cannot mangle the name of type 'bad_cast' into RTTI descriptors yet
error: cannot mangle RTTI descriptors for type 'exception' yet

error: cannot mangle RTTI descriptors for type 'bad_cast' yet
error: cannot mangle the name of type 'bad_cast' into RTTI descriptors yet
error: cannot mangle RTTI descriptors for type 'exception' yet
error: cannot mangle the name of type 'exception' into RTTI descriptors yet
error: cannot mangle RTTI descriptors for type 'bad_cast' yet
error: cannot mangle the name of type 'bad_cast' into RTTI descriptors yet
error: cannot mangle RTTI descriptors for type 'exception' yet
error: cannot mangle the name of type 'exception' into RTTI descriptors yet
error: cannot mangle RTTI descriptors for type 'bad_cast' yet
error: cannot mangle the name of type 'bad_cast' into RTTI descriptors yet
error: cannot mangle RTTI descriptors for type 'exception' yet
fatal error: too many errors emitted, stopping now [-ferror-limit=]
2 warnings and 20 errors generated.

And I can't find a switch for disabling exceptions.

Second problem (I think I've encountered this before and fixed it with 
-fno-delayed-template-parsing, however it doesn't seem to work on 
clang-cl or the argument has since been removed from clang)

Thanks a lot for your time.
