std::lower_bound is the canonical "binary search" in the STL
(std::binary_search generally is not what you want). The name actually
makes a lot of sense (and also has a beautiful symmetry with the
std::upper_bound algorithm). The name is nonetheless non-obvious.

Also, remove mention of "radix search". It's not even clear how that
would work in the context of a sorted vector. AFAIK "radix search" only
makes sense when you have a trie-like data structure.

When using modules we should not ignore overridden methods from
categories that are hidden because the module is not visible.
This will give more consistent results (when imports change) and it's more
correct since the methods are indeed overridden even if they are not "visible"
for lookup purposes.

[libclang] If libclang logging is enabled, print all compiler diagnostics to stderr instead of capturing them.

The array will decay into a pointer, creating an unexpected result.
sizeof(array + int) is an easy to make typo for sizeof(array) + int.

This was motivated by a NetBSD security bug, used sizeof(key - r) instead of
sizeof(key) - r, reducing entropy in a random number generator.

clang.arc.used is an interesting call for ARC since ObjCARCContract
needs to run to remove said intrinsic to avoid a linker error (since the
call does not exist).

Like nearbyint, rint can be implemented on PPC using the frin instruction. The
complication comes from the fact that rint needs to set the FE_INEXACT flag
when the result does not equal the input value (and frin does not do that). As
a result, we use a custom inserter which, after the rounding, compares the
rounded value with the original, and if they differ, explicitly sets the XX bit
in the FPSCR register (which corresponds to FE_INEXACT).

Once LLVM has better modeling of the floating-point environment we should be
able to (often) eliminate this extra complexity.

  can guarantee that all captured variables are available at -O0.

These instructions are available on the P5x (and later) and on the A2. They
implement the standard floating-point rounding operations (floor, trunc, etc.).
One caveat: frin (round to nearest) does not implement "ties to even", and so
is only enabled in fast-math mode.

We already avoided warning for

now we also don't produce any warnings for
