* Properly clear all the extra bits in a significand when making a NaN from anJohn McCall2010-02-281-8/+28
| | | | | | | | | APInt. Be certain to set the integer bit in an x87 extended-precision significand so that we don't accidentally make a pseudo-NaN. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97382 91177308-0d34-0410-b5e6-96231b3b80d8
* Add an override to StringRef::getAsInteger which parses into an APInt.John McCall2010-02-281-12/+93
| | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97381 91177308-0d34-0410-b5e6-96231b3b80d8
* Teach APFloat how to create both QNaNs and SNaNs and with arbitrary-widthJohn McCall2010-02-282-12/+45
| | | | | | | | | | payloads. APFloat's internal folding routines always make QNaNs now, instead of sometimes making QNaNs and sometimes SNaNs depending on the type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97364 91177308-0d34-0410-b5e6-96231b3b80d8

* Adding the MicroBlaze backend.Wesley Peck2010-02-231-0/+9
| | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96969 91177308-0d34-0410-b5e6-96231b3b80d8

* Refer to -help instead of --help since this is what tools themselves say.Duncan Sands2010-02-181-7/+7
| | | | | | | | | Also, have tools output -help-hidden rather than refer to --help-hidden, for consistency, and likewise adjust documentation. This doesn't change every mention of --help, only those which seemed clearly safe. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96578 91177308-0d34-0410-b5e6-96231b3b80d8
