raw_ostream: while it is generally desirable to do larger writes, it can lead to2011-03-04T19:49:30ZBenjamin Kramerbenny.kra@googlemail.com2011-03-04T19:49:30Zurn:sha1:ca9714470ec51ec52833eee46bca0062d92e92f3
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.2011-03-04T18:18:16ZBenjamin Kramerbenny.kra@googlemail.com2011-03-04T18:18:16Zurn:sha1:e90756d8a095264f6d6ae6b3a660e73c587162cd
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 approximation2011-02-21T00:22:02ZCameron Zwarichzwarich@apple.com2011-02-21T00:22:02Zurn:sha1:8d7285d0e5eb5937a6682e884b883516377e903d
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.
