Bug ID: 25871
Summary: Enum constants defined in Support/MachO.h conflict
with system header
Product: libraries
Version: 3.7
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: Support Libraries
Assignee: unassignedb...@nondot.org
Reporter: d...@danburkert.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
The OS X mach-o/loader.h system header defines a set of constants as macros,
and the LLVM Support/MachO.h header redefines those constants as enum variants
(MH_MAGIC is one example). The result is that in applications that import both
headers, the enum identifier in Support/MachO.h is replaced with the value, and
compilation fails.
OS X system header:
https://opensource.apple.com/source/xnu/xnu-1456.1.26/EXTERNAL_HEADERS/mach-o/loader.h
LLVM header:
https://github.com/llvm-mirror/llvm/blob/856a0380260e2735f51b059822674bd47961c050/include/llvm/Support/MachO.h#L24-L80
