* * Added basic support for JITing functions, basic blocks, instruction encoding,Misha Brukman2004-10-211-20/+169
| | | | | | | | | including registers, constants, and partial support for global addresses * The JIT is disabled by default to allow building llvm-gcc, which wants to test running programs during configure git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17149 91177308-0d34-0410-b5e6-96231b3b80d8

* Small performance improvement in generated C code:John Criswell2004-10-202-2/+46
| | | | | | | | | | | | | Instead of unconditionally copying all phi node values into temporaries for all successor blocks, generate code that will determine what successor block will be called and then copy only those phi node values needed by the successor block. This seems to cut down namd execution time from being 8% higher than GCC to 4% higher than GCC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17144 91177308-0d34-0410-b5e6-96231b3b80d8
* * Add baseline structural JIT code, but disable the JIT to allow llvm-gcc buildsMisha Brukman2004-10-192-16/+350
| | | | | | | | | - Support added for functions, basic blocks, constant pool, constants, registers, and some basic support for globals, all untested * Turn assert()s into abort()s so that unimplemented functions fail in release git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17143 91177308-0d34-0410-b5e6-96231b3b80d8
