Looking at r225438 inspired me to see how the PowerPC backend handled the situation (calling a bitcasted TLS global), and it turns out we also produced an error (cannot select ...). What it means to "call" something that is not a function is implementation and platform specific, but in the name of doing something (besides crashing), this makes sure we do what GCC does (treat all such calls as calls through a function pointer -- meaning that the pointer is assumed, as is the convention on PPC, to point to a function descriptor structure holding the actual code address along with the function's TOC pointer and environment pointer). As GCC does, we now do the same for calling regular (non-TLS) non-function globals too. I'm not sure whether this is the most useful way to define the behavior, but at least we won't be alone. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225617 91177308-0d34-0410-b5e6-96231b3b80d8 |
