[cfe-dev] inspecting emitted blocks code

[Abhishek Kulkarni]

Why are blocks excluded when printing out the AST? Is it a bug?

$ cat foo.c
#include<stdio.h>
int main(int argc, char *argv[])
{
        void (^hello)() = ^ { printf("hello world\n"); };
        hello();
        return 0;
}

$ clang -cc1 -fblocks hello.c -ast-print
int main(int argc, char *argv[]) {
    void (^hello)() = ^;
    hello();
    return 0;
}

In any case, is there a quick way to dump the blocks-specific generated code
(__block_invoke_1, __block_literal_1 etc.)?
Finally, is there a way to reach a block's imported variables without
modifying the compiler?

Thanks,
Abhishek
