Which version of binary did you use? There were similar problems a
while ago, but, IIRC, they're supposed to be fixed (apparently too
*many* INLINE pragmas were the problem).

Hi,
I'm parsing Java classfiles with Data.Binary, the code is here: http://paste.org/index.php?id=4625
The problem is that the resulting code parses rt.jar from JDK6 (about 15K classes, 47Mb zipped) in 15 seconds (run the program with main -mclose rt.jar, for instance), which is 10 times slower than my Java version of the same code.
I compile the program with -O2 ; I tried -ddump-inlinings and it turns out that my readByte/readWord16/readWord32 functions don't get inlined, despite being simply aliases for 'get::Get WordXX'; so, in places where my Java version does a pointer access (after being JIT-compiled), the Haskell version does two function calls.
What can be the reason of this lack of inlining? Or how do I understand the output of -ddump-inlinings?
