* Switch the asmprinter (.ll) and all the stuff it requires over toChris Lattner2008-08-231-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | use raw_ostream instead of std::ostream. Among other goodness, this speeds up llvm-dis of kc++ with a release build from 0.85s to 0.49s (88% faster). Other interesting changes: 1) This makes Value::print be non-virtual. 2) AP[S]Int and ConstantRange can no longer print to ostream directly, use raw_ostream instead. 3) This fixes a bug in raw_os_ostream where it didn't flush itself when destroyed. 4) This adds a new SDNode::print method, instead of only allowing "dump". A lot of APIs have both std::ostream and raw_ostream versions, it would be useful to go through and systematically anihilate the std::ostream versions. This passes dejagnu, but there may be minor fallout, plz let me know if so and I'll fix it. llvm-svn: 55263
* Move the fast-path (<=i64) cases of various APInt methods inlineChris Lattner2008-08-201-150/+40

* Rework the routines that convert AP[S]Int into a string. Now, instead ofChris Lattner2008-08-171-95/+98
| | | | | | | | | | | | | | | | | returning an std::string by value, it fills in a SmallString/SmallVector passed in. This significantly reduces string thrashing in some cases. More specifically, this: - Adds an operator<< and a print method for APInt that allows you to directly send them to an ostream. - Reimplements APInt::toString to be much simpler and more efficient algorithmically in addition to not thrashing strings quite as much. This speeds up llvm-dis on kc++ by 7%, and may also slightly speed up the asmprinter. This also fixes a bug I introduced into the asmwriter in a previous patch w.r.t. alias printing. llvm-svn: 54873

* Add a new function tcExtract for extracting a bignum from anNeil Booth2007-10-081-34/+76
| | | | | | | | | | | | | arbitrary range of bits embedded in the middle of another bignum. This kind of operation is desirable in many cases of software floating point, e.g. converting bignum integers to floating point numbers of fixed precision (you want to extract the precision most significant bits). Elsewhere, add an assertion, and exit the shift functions early if the shift count is zero. llvm-svn: 42745

Make APInt::dump() public, remove newline, use it to dump ConstantSDNode's. Allow APFloats in FoldingSet. Expand X86 backend handling of long doubles (conversions to/from int, mostly). llvm-svn: 41967
