I looked into it, I am not sure if anything special needs to be done for block.
ie:
echo "void f() { __block int x = 42; void (^sum)(int) = ^(int y) { x = x + y;
}; }" | clang -x c -fblocks -o - - -c | llvm-nm -
U _Block_object_assignecho "void f() { __block int x = 42;
void (^sum)(int) = ^(int y) { x = x + y; }; }" | clang -x c -fblocks -o - - -c
| llvm-nm -
