Kostya Serebryany 164b86b439 Extend Attributes to 64 bits ... Problem: LLVM needs more function attributes than currently available (32 bits). One such proposed attribute is "address_safety", which shows that a function is being checked for address safety (by AddressSanitizer, SAFECode, etc). Solution: - extend the Attributes from 32 bits to 64-bits - wrap the object into a class so that unsigned is never erroneously used instead - change "unsigned" to "Attributes" throughout the code, including one place in clang. - the class has no "operator uint64 ()", but it has "uint64_t Raw() " to support packing/unpacking. - the class has "safe operator bool()" to support the common idiom: if (Attributes attr = getAttrs()) useAttrs(attr); - The CTOR from uint64_t is marked explicit, so I had to add a few explicit CTOR calls - Add the new attribute "address_safety". Doing it in the same commit to check that attributes beyond first 32 bits actually work. - Some of the functions from the Attribute namespace are worth moving inside the class, but I'd prefer to have it as a separate commit. Tested: "make check" on Linux (32-bit and 64-bit) and Mac (10.6) built/run spec CPU 2006 on Linux with clang -O2. This change will break clang build in lib/CodeGen/CGCall.cpp. The following patch will fix it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148553 91177308-0d34-0410-b5e6-96231b3b80d8		2012-01-20 17:56:17 +00:00
