* Add raw_stream adaptors that write into an std::string and ↵Chris Lattner2008-08-231-0/+35

* Switch the asmprinter (.ll) and all the stuff it requires over toChris Lattner2008-08-233-9/+17
| | | | | | | | | | | | | | | | | | | | | | | | 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 Lattner2008-08-173-99/+100
| | | | | | | | | | | | | | | | | 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

* Fold the useful features of alist and alist_node into ilist, andDan Gohman2008-07-281-2/+4
| | | | | | | | | | | | | | | | a new ilist_node class, and remove them. Unlike alist_node, ilist_node doesn't attempt to manage storage itself, so it avoids the associated problems, including being opaque in gdb. Adjust the Recycler class so that it doesn't depend on alist_node. Also, change it to use explicit Size and Align parameters, allowing it to work when the largest-sized node doesn't have the greatest alignment requirement. Change MachineInstr's MachineMemOperand list from a pool-backed alist to a std::list for now. llvm-svn: 54146
