[LLVMdev] noreturn attribute on a call instruction vs noreturn on afunction
You can use CallInst::hasFnAttr(). It checks for attributes in the
instruction and in the function decl.

[LLVMdev] noreturn attribute on a call instruction vs noreturn on a function
Hi,
Building the following C code I get a call instruction that has no noreturn
attribute, while the function itself does have it.
void foo(void **b) {
__builtin_longjmp(b, 1);
}
define void @_Z3fooPPv(i8** %b) noreturn nounwind uwtable {
entry:
%0 = bitcast i8** %b to i8*
tail call void @llvm.eh.sjlj.longjmp(i8* %0)
