2004-02-23Refactor rewinding code for finding the first terminator of a basicAlkis Evlogimenos
block into MachineBasicBlock::getFirstTerminator(). This also fixes a bug in the implementation of the above in both RegAllocLocal and InstrSched, where instructions where added after the terminator if the basic block's only instruction was a terminator (it shouldn't matter for RegAllocLocal since this case never occurs in practice). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11748 91177308-0d34-0410-b5e6-96231b3b80d8

2004-02-22Only insert FP_REG_KILL instructions in MachineBasicBlocks that actuallyChris Lattner
use FP instructions. This reduces the number of instructions inserted in 176.gcc (for example) from 58074 to 101 (it doesn't use much FP, which is typical). This reduction speeds up the entire code generator. In the case of 176.gcc, llc went from taking 31.38s to 24.78s. The passes that sped up the most are the register allocator and the 2 live variable analysis passes, which sped up 2.3, 1.3, and 1.5s respectively. The asmprinter pass also sped up because it doesn't print the instructions in comments :) Note that this patch is likely to expose latent bugs in machine code passes, because now basicblock can be empty, where they were never empty before. I cleaned out regalloclocal, but who knows about linscan :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11717 91177308-0d34-0410-b5e6-96231b3b80d8

2004-02-22Move MOTy::UseType enum into MachineOperand. This eliminates theAlkis Evlogimenos
switch statements in the constructors and simplifies the implementation of the getUseType() member function. You will have to specify defs using MachineOperand::Def instead of MOTy::Def though (similarly for Use and UseAndDef). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11715 91177308-0d34-0410-b5e6-96231b3b80d8

2004-02-22Completely rewrite how getelementptr instructions are expanded. This has twoChris Lattner
(minor) benefits right now: 1. An extra dummy MOVrr32 is gone. This move would often be coallesced by both allocators anyway. 2. The code now uses the gep_type_iterator to walk the gep, which should future proof it a bit. It still assumes that array indexes are Longs though. These don't really justify rewriting the code. The big benefit will come later though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11710 91177308-0d34-0410-b5e6-96231b3b80d8
