* Twines: Support numeric conversion directly (uitostr, etc).Daniel Dunbar2009-07-291-0/+12
| | | | | | | | | | | | | | | | - Provides static constructors for doing number to string conversions without using temporaries. - There are several ways to do this, I think given the Twine constraints this is the simplest one. - One FIXME for fast number -> hex conversion. - Added another comment on one last major bit of perf work Twines need, which is to make raw_svector_ostream more efficient. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77445 91177308-0d34-0410-b5e6-96231b3b80d8

Also, switch function stubs and global data over to using the BumpPtrAllocator. This makes it so the JIT no longer mmaps (or the equivalent on Windows) 16 MB of memory, and instead allocates in 512K slabs. I suspect this size could go lower, especially on embedded platforms, now that more slabs can be allocated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76828 91177308-0d34-0410-b5e6-96231b3b80d8
