* For PR411:Reid Spencer2006-01-161-11/+23
| | | | | | | | | | | | | | | | This patch is an incremental step towards supporting a flat symbol table. It de-overloads the intrinsic functions by providing type-specific intrinsics and arranging for automatically upgrading from the old overloaded name to the new non-overloaded name. Specifically: llvm.isunordered -> llvm.isunordered.f32, llvm.isunordered.f64 llvm.sqrt -> llvm.sqrt.f32, llvm.sqrt.f64 llvm.ctpop -> llvm.ctpop.i8, llvm.ctpop.i16, llvm.ctpop.i32, llvm.ctpop.i64 llvm.ctlz -> llvm.ctlz.i8, llvm.ctlz.i16, llvm.ctlz.i32, llvm.ctlz.i64 llvm.cttz -> llvm.cttz.i8, llvm.cttz.i16, llvm.cttz.i32, llvm.cttz.i64 New code should not use the overloaded intrinsic names. Warnings will be emitted if they are used. llvm-svn: 25366

| | | | | | | | | | | | | pointer marking the end of the list, the zero *must* be cast to the pointer type. An un-cast zero is a 32-bit int, and at least on x86_64, gcc will not extend the zero to 64 bits, thus allowing the upper 32 bits to be random junk. The new END_WITH_NULL macro may be used to annotate a such a function so that GCC (version 4 or newer) will detect the use of un-casted zero at compile time. llvm-svn: 23888
