* Change all machine basic block modifier functions in MRegisterInfo toAlkis Evlogimenos2003-11-042-41/+54
| | | | | | | | | | | | | | | | return the number of instructions added to/removed from the basic block passed as their first argument. Note: This is only needed because we use a std::vector instead of an ilist to keep MachineBasicBlock instructions. Inserting an instruction to a MachineBasicBlock invalidates all iterators to the basic block. The return value can be used to update an index to the machine basic block instruction vector and circumvent the iterator elimination problem but this is really not needed if we move to a better representation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9704 91177308-0d34-0410-b5e6-96231b3b80d8

* Emit x86 instructions for: A = B op C, where A and B are 16-bit registers,Chris Lattner2003-10-203-0/+94
| | | | | | | | | | | | | | | | | | | | | | | C is a constant which can be sign-extended from 8 bits without value loss, and op is one of: add, sub, imul, and, or, xor. This allows the JIT to emit the one byte version of the constant instead of the two or 4 byte version. Because these instructions are very common, this can save a LOT of code space. For example, I sampled two benchmarks, 176.gcc and 254.gap. BM Old New Reduction 176.gcc 2673621 2548962 4.89% 254.gap 498261 475104 4.87% Note that while the percentage is not spectacular, this did eliminate 124.6 _KILOBYTES_ of codespace from gcc. Not bad. Note that this doesn't effect the llc version at all, because the assembler already does this optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9284 91177308-0d34-0410-b5e6-96231b3b80d8
