git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10447 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-13Add a floating point killer pass. This pass runs before registerAlkis Evlogimenos
allocaton on the X86 to add information to the machine code denoting that our floating point stackifier cannot handle virtual point register that are alive across basic blocks. This pass adds an implicit def of all virtual floating point register at the end of each basic block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10446 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

2003-12-11In getObjectType(), doxygenify comment, and take a pointer to theBrian Gaeke
beginning of the archive member data as an argument. Get rid of ParseLongFilenameSection(), which is dead. In ReadArchiveBuffer(), implement support for 4.4BSD/MacOSX long filenames. This is kind of invasive, because they prepend the long filename to the archive member data, and then lie about the size. So we have to keep track of the real size. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10392 91177308-0d34-0410-b5e6-96231b3b80d8

2003-12-11Add support for --debug-only=interpreter, to print out instrs beforeBrian Gaeke
interpreting them. Move support for getting the value of a ConstantExpr into getConstantExprValue(), and add support for the rest of the different kinds of ConstantExprs. (I don't think I like ConstantExprs!) This requires separate procedures executeShlInst() and executeShrInst(). Reduce the number of references to TheEE. Get rid of an old comment mentioning annotations. Fix exitCalled(), which was crashing the Interpreter. This was a leftover from the return-value code refactoring. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10389 91177308-0d34-0410-b5e6-96231b3b80d8

2003-12-10Fixed the CBE on Solaris/Sparc. We need to define the return value ofJohn Criswell
the write() system call because it returns 64 bits on Solaris 64 bit, and an implicit return value of int says it returns 32 bits. Admittedly, this is a bit of a hack. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10375 91177308-0d34-0410-b5e6-96231b3b80d8

2003-12-08Cleanup and restructure the code to make it easier to read and maintain.Chris Lattner
The only functionality change is that we now implement: Regression/Transforms/TailCallElim/intervening-inst.ll Which is really kinda pointless, because it means that trivially dead code does not interfere with -tce, but trivially dead code probably wouldn't be around anytime when this pass is run anyway. The point of including this change it to support other more aggressive transformations when we have the analysis capabilities to do so. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10312 91177308-0d34-0410-b5e6-96231b3b80d8
