[LLVMdev] [Patches][RFC] What to do about bitcode streaming.
...t;It might be even possible to drop the requirement
for the size to be known: Replace the call to AtEndOfStream by just trying
to read more and checking if it failed, but that is a bit more than I
wanted to do for this."
That is to remove some calls to getSize()? Is there any expectation that
getPointer() will always a pointer within a contiguous region of memory?
That is, getPointer() is non-virtual and always refers to the Data field,
but the overriding implementation could still dynamically grow some buffer
and change Data to point to a new buffer (could that be "protected"
instead?)?...

[LLVMdev] [Patches][RFC] What to do about bitcode streaming.
Hi Rafael,
Would you mind waiting for Derek to come back from vacation to discuss
this? We do use this code and could improve how it's used and tested within
LLVM. Derek is the best person to discuss this, he'll be back in
mid-January.
Thanks,
JF
