significand so that we don't accidentally make a pseudo-NaN.

Add an override to StringRef::getAsInteger which parses into an APInt.2010-02-28T09:55:58ZJohn McCallrjmccall@apple.com2010-02-28T09:55:58Zurn:sha1:1e7ad3993d8700488895fa372ecad55443f53485
It gets its own implementation totally divorced from the (presumably
performance-sensitive) routines which parse into a uint64_t.
Add APInt::operator|=(uint64_t), which is situationally much better than
using a full APInt.

Teach APFloat how to create both QNaNs and SNaNs and with arbitrary-width2010-02-28T02:51:25ZJohn McCallrjmccall@apple.com2010-02-28T02:51:25Zurn:sha1:e12b73816b50bbe2cc54b8005d86c95413b4f465

instead of sometimes making QNaNs and sometimes SNaNs depending on the
type.

Adding the MicroBlaze backend.2010-02-23T19:15:24ZWesley Peckpeckw@wesleypeck.com2010-02-23T19:15:24Zurn:sha1:a70f28ce7dc85d0075a7d86da5d7987b6e306bc6
The MicroBlaze is a highly configurable 32-bit soft-microprocessor for
use on Xilinx FPGAs. For more information see:
http://www.xilinx.com/tools/microblaze.htm
http://en.wikipedia.org/wiki/MicroBlaze
The current LLVM MicroBlaze backend generates assembly which can be
compiled using the an appropriate binutils assembler.
