2004-05-14Don't keep track of references to LLVM BasicBlocks while emitting; useBrian Gaeke
MachineBasicBlocks instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13568 91177308-0d34-0410-b5e6-96231b3b80d8

2004-02-28Each instruction now has both an ImmType and a MemType. This describesAlkis Evlogimenos
the size of the immediate and the memory operand on instructions that use them. This resolves problems with instructions that take both a memory and an immediate operand but their sizes differ (i.e. ADDmi32b). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11967 91177308-0d34-0410-b5e6-96231b3b80d8

2004-02-17Expand the repertoire of the forms we can print and encode.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11537 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-15Make dense maps keyed on physical registers smallerusingAlkis Evlogimenos
MRegisterInfo::getNumRegs() instead of MRegisterInfo::FirstVirtualRegister. Also use MRegisterInfo::is{Physical,Virtual}Register where appropriate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11477 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-15Add back machine code deleter pass until we get a MachineCode passAlkis Evlogimenos
that will be responsible for the creation of MachineFunctions and will be required by all MachineFunctionPass passes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11453 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-12Add support for the rep movs[bwd] instructions, and emit them when codeChris Lattner
generating the llvm.memcpy intrinsic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11351 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-12Change MachineBasicBlock's vector of MachineInstr pointers into anAlkis Evlogimenos
ilist of MachineInstr objects. This allows constant time removal and insertion of MachineInstr instances from anywhere in each MachineBasicBlock. It also allows for constant time splicing of MachineInstrs into or out of MachineBasicBlocks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11340 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-04Modify the two address instruction pass to remove the duplicateAlkis Evlogimenos
operand of the instruction and thus simplify the register allocation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11124 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-20Remove floating point killer pass. This is now implemented in theAlkis Evlogimenos
instruction selector by adding a new pseudo-instruction FP_REG_KILL. This instruction implicitly defines all x86 fp registers and is a terminator so that passes which add machine code at the end of basic blocks (like phi elimination) do not add instructions between it and the branch or return instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10562 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-20Finally, _actually delete the machine code_ for a function, after it hasChris Lattner
been emitted. Also, since the FPK pass is causing memory access violations, disable it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10559 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-20A minor cleanup for better encapsulationChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10545 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-20Rip JIT specific stuff out of TargetMachine, as per PR176Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10542 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-12Modified cast so that it converts the int to a long before casting toJohn Criswell
a pointer. This evades a warning emitted by GCC when we cast from unsigned int (32 bit) to void * (64 bit) on SparcV9. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10435 91177308-0d34-0410-b5e6-96231b3b80d8

2003-10-20Added LLVM project notice to the top of every C++ source file.John Criswell
Header files will be on the way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9298 91177308-0d34-0410-b5e6-96231b3b80d8
2003-10-20* Rename X86::IMULr16 -> X86::IMULrr16Chris Lattner
* Implement R1 = R2 * C where R1 and R2 are 32 or 16 bits. This avoids an extra copy into a register, reducing register pressure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9278 91177308-0d34-0410-b5e6-96231b3b80d8
