2004-08-21Register info alignment is in bits, frame object alignment is (currently) inChris Lattner
bytes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15970 91177308-0d34-0410-b5e6-96231b3b80d8
2004-08-21Now that we have per-register spill size/alignment info, remove more usesChris Lattner

2004-08-12Split saveCallerSavedRegisters into two methods for clarity, and add comments.Chris Lattner
Add support for targets that must spill certain physregs at certain locations. Patch contributed by Nate Begeman, slightly hacked by me. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15701 91177308-0d34-0410-b5e6-96231b3b80d8

2004-06-11Fix fallout from getOffsetOfLocalArea() being negated. Debugging dumps were ↵Chris Lattner
being printed incorrectly, and we were reserving 8 extra bytes of stack space for functions on X86. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14152 91177308-0d34-0410-b5e6-96231b3b80d8
2004-06-10Fix the prolog epilog code inserter to match the documentation and supportChris Lattner
targets whose stack grows up. Patch contributed by Vladimir Prus git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14111 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

clobber them by allocating other objects in the same space! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11454 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-14There is no reason to align the stack pointer if there are no callees of ↵Chris Lattner
this function! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11449 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
2004-02-10Do not use MachineOperand::isVirtualRegister either!Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11283 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-10Eliminate users of MachineOperand::isPhysicalRegisterChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11278 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-14Change interface of MachineOperand as follows:Alkis Evlogimenos
a) remove opIsUse(), opIsDefOnly(), opIsDefAndUse() b) add isUse(), isDef() c) rename opHiBits32() to isHiBits32(), opLoBits32() to isLoBits32(), opHiBits64() to isHiBits64(), opLoBits64() to isLoBits64(). This results to much more readable code, for example compare "op.opIsDef() || op.opIsDefAndUse()" to "op.isDef()" a pattern used very often in the code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10461 91177308-0d34-0410-b5e6-96231b3b80d8
2003-11-11Put all LLVM code into the llvm namespace, as per bug 109.Brian Gaeke
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9903 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
2003-10-08Change MRegisterDesc::AliasSet, TargetInstrDescriptor::ImplicitDefsAlkis Evlogimenos
and TargetInstrDescriptor::ImplicitUses to always point to a null terminated array and never be null. So there is no need to check for pointer validity when iterating over those sets. Code that looked like: if (const unsigned* AS = TID.ImplicitDefs) { for (int i = 0; AS[i]; ++i) { // use AS[i] } } was changed to: for (const unsigned* AS = TID.ImplicitDefs; *AS; ++AS) { // use *AS } git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8960 91177308-0d34-0410-b5e6-96231b3b80d8

2003-05-27(1) Added special register class containing (for now) %fsr.Vikram S. Adve
Fixed spilling of %fcc[0-3] which are part of %fsr. (2) Moved some machine-independent reg-class code to class TargetRegInfo from SparcReg{Class,}Info. (3) Renamed MachienOperand::opIsDef to MachineOperand::opIsDefOnly() and related functions and flags. Fixed several bugs where only "isDef" was being checked, not "isDefAndUse". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6341 91177308-0d34-0410-b5e6-96231b3b80d8
