Bug ID: 31904
Summary: Legacy libc++abi configuration logic in libc++?
Product: libc++
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: unassignedclangb...@nondot.org
Reporter: e...@efcs.ca
CC: llvm-bugs@lists.llvm.org, mclow.li...@gmail.com
Classification: Unclassified
The configuration in question is seen in exception.cpp:24 and new.cpp:20. In
these places it configures for a `cxxabi.h` which (1) doesn't define
`_LIBCPPABI_VERSION` and (2) defines a special namespace `__cxxabiapple`.
As mentioned I believe this configuration is dead. libc++abi's cxxabi.h has
been defining `_LIBCPPABI_VERSION` since 2012, and I can't find any evidence of
the `__cxxabiapple` namespace.
@Duncan do you know where this weird `cxxabi.h` header is coming from? Or if
Apple still uses it?
