* As discussed on the mailing list,
|
|
forced no-rtti breaks C++ public
|
|
API's such as the Haiku C++ libGL.so
|
|
* -fno-rtti *can* be still set however
|
|
instead of blindly forcing -fno-rtti,
|
|
we can rely on the llvm-config
|
|
--cppflags output.
|
|
If the system llvm is built without
|
|
rtti (default), the no-rtti flag will be
|
|
present in llvm-config --cppflags
|
|
(which we pick up on)
|
|
If llvm is built with rtti
|
|
(REQUIRES_RTTI=1), then -fno-rtti is
|
|
removed from llvm-config --cppflags.
|
|
* We could selectively add / remove rtti
|
|
from various components, however mixing
|
|
rtti and non-rtti code is tricky and
|
|
could introduce bugs.
|
|
* This needs impact tested.
