2008-08-17Factor GC metadata table assembly generation out of Collector in preparation ↵Gordon Henriksen
for splitting AsmPrinter into its own library. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54880 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-17Rework the routines that convert AP[S]Int into a string. Now, instead ofChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54873 91177308-0d34-0410-b5e6-96231b3b80d8

LowerSubregs, and fix an x86-64 isel bug that this exposed.
