raw_ostream: while it is generally desirable to do larger writes, it can lead to
...
inefficient file system buffering if the writes are not a multiple of the desired
buffer size. Avoid this by limiting the large write to a multiple of the buffer
size and copying the remainder into the buffer.
Thanks to Dan for pointing this out.

raw_ostream: If writing a string that is larger than the buffer, write it directly instead of doing many buffer-sized writes.

This caps the number of write(2) calls per string to a maximum of 2.

The signed version of our "magic number" computation for the integer approximation
...
of a constant had a minor typo introduced when copying it from the book, which
caused it to favor negative approximations over positive approximations in many
cases. Positive approximations require fewer operations beyond the multiplication.
In the case of division by 3, we still generate code that is a single instruction
larger than GCC's code.

Clang was not parsing target triples involving EABI and was generating wrong IR (wrong PCS) and passing the wrong information down llc via the target-triple printed in IR. I've fixed this by adding the parsing of EABI into LLVM's Triple class and using it to choose the correct PCS in Clang's Tools. A Clang patch is on its way to use this infrastructure.
