[LLVMdev] next
In many places there is code that looks like:
MBBI = next(MBBI);
In C++0X there is a std::next that is likely to be in scope when these
calls are made. And due to ADL the above call becomes ambiguous:
llvm::next or std::next?
I recommend:
MBBI = llvm::next(MBBI);

[PATCH nbdkit 3/3] server: filters: Remove struct b_h.
This was previously used as ‘nxdata’ and stored a tuple of ’b->next’
and the real filter handle. However after recent changes we don't
need it. We can use ‘b->next’ as nxdata, and the handle is passed to
us by the calling functions.
Inspired by Eric Blakes observations in this email:

[LLVMdev] 'loop invariant code motion' and 'Reassociate Expression'
...similar degradation)
One issue I see is the following:
- 'loop invariant code motion' seems to be depending on the result of the 'reassociate expression' pass:
In the samples below I observer the following behavior:
Both start with the same expression:
%add = add i32 %total.0, %next.0
%add1 = add i32 %add, 1
-LLVM-3.1 converts this into:
--after Reassociate expressions:
%add = add i32 %next.0, 1
%add1 = add i32 %add, %total.0
-- after Canonicalize natural loops:
%add = add i32 %next.0.ph, 1
%add1 = add i32 %add, %total.0
-- and during 'loop invariant code motion...

meet some condition, then I want it to go next, and generate data again for
next round.
# just an example..
# i want to generate the data again, if the sum is smaller than 25
