the transformed LLVM code which is the input to the instruction selector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13879 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-28Fix the big regression that has been killing the nightly tester these lastChris Lattner
few days. Apparently the old symbol table used to auto rename collisions in the type symbol table and the new one does not. It doesn't really make sense for the new one to do so, so we just make the client do it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13877 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-28Add support for getting executable memory on Windows. This is actuallyChris Lattner
much easier than on unix. :) The only evil thing is that windows.h defines a macro named FindExecutable, which collides with one of our names. The JIT now runs on windows, but it cannot resolve external functions (like printf) yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13871 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-27Fix for bug 348.Reid Spencer
The SymbolTable changes caused this one too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13859 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-27Fix a bug in the -deadtypeelim pass. The SymbolTable re-write changed itJohn Criswell
to eliminate the wrong type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13855 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-27Use the SymbolTable::isEmpty() method instead of checking for no valueReid Spencer
planes. A SymbolTable could still have types in it! This fixes problems with two regression tests that failed because a symbol table that only contained types was being omitted from bytecode files. Thanks to Chris for the reduced test case that helped find this immediately. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13842 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-27This code is a real mess, but at least get the JIT *building* on platformsChris Lattner
(such as plan 9) without mmap. Of course it won't RUN... but that's another step. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13839 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-27Fix InstCombine/load.ll & PR347.Chris Lattner
This code hadn't been updated after the "structs with more than 256 elements" related changes to the GEP instruction. Also it was not handling the ConstantAggregateZero class. Now it does! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13834 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-27Implement constant folding of fmod, which is used a lot in povrayChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13823 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-27Restructure call constant folding code a bit to make it simplerChris Lattner
Add support for acos/asin/atan. 188.ammp contains three calls to acos with constant arguments. Constant folding it allows elimination of those 3 calls and three FP divisions of the results. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13821 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-27Signals.h header moved. Eventually this should move into a lib/System library,Chris Lattner
but not right now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13811 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13806 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-27Add constructors that take a BasicBlock to append to, to the rest ofAlkis Evlogimenos
the llvm::Instruction hierarchy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13800 91177308-0d34-0410-b5e6-96231b3b80d8

appended anywhere. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13798 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-26Several clean ups suggested by Chris: remove tabs, make SlotMachine do lazyReid Spencer
initialization so we don't scan large Modules/Functions needlessly, tighten up restrictions on what can be put in SlotMachine (no Constants that aren't GlobalValues). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13796 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-26Provide the correct patch for bug 345. The solution is to add a setTypeNameReid Spencer
function to llvmAsmParser.y and then use it in the one place in the grammar that needs it. Also had to make Type::setName public because setTypeName needs it in order to retain compatibility with setValueName. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13795 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-26Refactor common initialization code in private init() functions.Alkis Evlogimenos
This is a first step in supplying append to basic block constructors for all instruction types. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13793 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-26Fix PR344: the incorrect remove was being used.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13790 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-26A quick and ugly hack to fix PR345. I used TypeTy specifically to makeChris Lattner
Reid cringe :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13788 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-26Part of bug 122:Reid Spencer
This change removes the BuildBytecodeInfo flag from the SlotCalculator class. This flag was needed to distinguish between the Bytecode/Writer and the AsmWriter. Now that AsmWriter doesn't use SlotCalculator, we can remove this flag and simplify some code. Also, some minor name changes to CachedWriter.h needed to be committed (missed in previous commit). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13785 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-26Part of bug 122. Removed dependency of AsmWriter on SlotCalculator byReid Spencer
incorporating a significantly simpler "SlotMachine" into this file. The SlotMachine is tailored for use by only the AsmWriter whose requirements for slot numbers are vastly different than from the Bytecode/Writer. Code change passes all Feature and Regression tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13784 91177308-0d34-0410-b5e6-96231b3b80d8

compliant. Thanks, Chris. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13771 91177308-0d34-0410-b5e6-96231b3b80d8

SlotTable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13766 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13765 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-25Adding the initial implementation of the SlotTable class. This class isReid Spencer
the Abstract Data Type that holds slot number values and associates them with Type* and Value*. The SlotTable is simply the holder of the slot numbers and provides a controlled interface for building the table. It does not enforce any particular idiom or functionality for manipulating the slot numbers. This is part of bug_122. The SlotCalculator and SlotMachine classes will follow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13764 91177308-0d34-0410-b5e6-96231b3b80d8
