* Fix some thinko's in the last patch. PtrSize has to be in bits and weReid Spencer2007-03-061-2/+2
| | | | | | might need to zext not just trunc the value. llvm-svn: 34955
* Fix a bug in IntToPtr. Truncating to 64-bits only works if the integerReid Spencer2007-03-061-1/+5
| | | | | | is larger. Adjust so that it truncates to pointer width, only if necessary. llvm-svn: 34954
* Radically simplify execution. This patch gets rid of all the specialReid Spencer2007-03-061-636/+128
| | | | | | | | handling for integer of various sizes. GenericValue now has just a single integer field of type APInt. We use its facilities directly in the execution of all instructions. llvm-svn: 34951
* Complete the APIntification of the interpreter. All asserts for > 64 bitsReid Spencer2007-03-031-118/+209
| | | | | | | have been removed and dealt with. The interpreter should now be able to execute any LLVM program using any bit width. llvm-svn: 34884
* Implement APInt support for the binary operators.Reid Spencer2007-03-031-254/+240
| | | | | | | Move the getConstantExpr function towards the end of the file so we don't need a dozen forward declarations. llvm-svn: 34877
* From Dan Gohman:Chris Lattner2007-02-141-1/+1
| | | | | | | | | | While preparing http://llvm.org/PR1198 I noticed several asserts protecting unprepared code from i128 types that weren't actually failing when they should because they were written as assert("foo") instead of something like assert(0 && "foo"). This patch fixes all the cases that a quick grep found. llvm-svn: 34267

| | | | | | | | Compute BitMask correctly. Patch by Leo (wenwenti@hotmail.com). llvm-svn: 34026
* Changes to support making the shift instructions be true BinaryOperators.Reid Spencer2007-02-021-3/+3
| | | | | | | | | | | | This feature is needed in order to support shifts of more than 255 bits on large integer types. This changes the syntax for llvm assembly to make shl, ashr and lshr instructions look like a binary operator: shl i32 %X, 1 instead of shl i32 %X, i8 1 Additionally, this should help a few passes perform additional optimizations. llvm-svn: 33776
* For PR1136: Rename GlobalVariable::isExternal as isDeclaration to avoidReid Spencer2007-01-301-2/+2
| | | | | | confusion with external linkage types. llvm-svn: 33663
* For PR970:Reid Spencer2007-01-211-1/+1
| | | | | | | Clean up handling of isFloatingPoint() and dealing with PackedType. Patch by Gordon Henriksen! llvm-svn: 33415
* Implement the signed icmp instructions properly. To do this we introduceReid Spencer2007-01-201-17/+27
| | | | | | | | a small inline function to sign extend a uint64_t value based on its type's bitwidth. This function is then used in both executeSExtInst and the various executeICMP_S** functions. llvm-svn: 33403

| | | | | | | sufficient to get llvm-test/SingleSource/UnitTests/Integer/general-test.ll working with lli in interpreter mode. llvm-svn: 33321
* Two changes:Reid Spencer2007-01-181-18/+17
| | | | | | | | | 1. Fix logic for executeGEP. Only 32-bit and 64-bit integer types are acceptable as indices. 2. Ensure that all integer cast operations truncate their result to the integer size of the operand. llvm-svn: 33318
* rename Type::isIntegral to Type::isInteger, eliminating the old Type::isInteger.Chris Lattner2007-01-151-6/+6
| | | | | | | | | rename Type::getIntegralTypeMask to Type::getIntegerTypeMask. This makes naming much more consistent. For example, there are now no longer any instances of IntegerType that are not considered isInteger! :) llvm-svn: 33225
* eliminate calls to Type::isInteger, preferring isIntegral instead.Chris Lattner2007-01-151-4/+4

* For PR1064:Reid Spencer2007-01-121-379/+686
| | | | | | | | | | | | | | | | | | | | | | | Implement the arbitrary bit-width integer feature. The feature allows integers of any bitwidth (up to 64) to be defined instead of just 1, 8, 16, 32, and 64 bit integers. This change does several things: 1. Introduces a new Derived Type, IntegerType, to represent the number of bits in an integer. The Type classes SubclassData field is used to store the number of bits. This allows 2^23 bits in an integer type. 2. Removes the five integer Type::TypeID values for the 1, 8, 16, 32 and 64-bit integers. These are replaced with just IntegerType which is not a primitive any more. 3. Adjust the rest of LLVM to account for this change. Note that while this incremental change lays the foundation for arbitrary bit-width integers, LLVM has not yet been converted to actually deal with them in any significant way. Most optimization passes, for example, will still only deal with the byte-width integer types. Future increments will rectify this situation. llvm-svn: 33113

* For PR950:Reid Spencer2006-12-231-112/+329
| | | | | | | | This patch removes the SetCC instructions and replaces them with the ICmp and FCmp instructions. The SetCondInst instruction has been removed and been replaced with ICmpInst and FCmpInst. llvm-svn: 32751

* For PR950:Reid Spencer2006-11-271-34/+179
| | | | | | | | | | The long awaited CAST patch. This introduces 12 new instructions into LLVM to replace the cast instruction. Corresponding changes throughout LLVM are provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the exception of 175.vpr which fails only on a slight floating point output difference. llvm-svn: 31931

* For PR950:Reid Spencer2006-11-081-19/+50
| | | | | | | | This patch converts the old SHR instruction into two instructions, AShr (Arithmetic) and LShr (Logical). The Shr instructions now are not dependent on the sign of their operands. llvm-svn: 31542

* Fix a bug in the interpreter where divides of unmatched signed operandsReid Spencer2006-11-011-8/+11
| | | | | | | would fail. E.g. udiv sint X, Y or sdiv uint X, Y would fail to find a type match in the switch statement and fail the operation. llvm-svn: 31338
* For PR950:Reid Spencer2006-10-261-11/+51
| | | | | | | | Make necessary changes to support DIV -> [SUF]Div. This changes llvm to have three division instructions: signed, unsigned, floating point. The bytecode and assembler are bacwards compatible, however. llvm-svn: 31195
* For PR950:Reid Spencer2006-10-201-2/+2
| | | | | | | | This patch implements the first increment for the Signless Types feature. All changes pertain to removing the ConstantSInt and ConstantUInt classes in favor of just using ConstantInt. llvm-svn: 31063
* The interpreter assumes that the caller of runFunction() must be lli, andJeff Cohen2006-02-071-3/+3
| | | | | | | | therefore the function being called must be a main() returning an int. The consequences when these assumptions are false are not good, so don't assume them. llvm-svn: 26031

* Go back to the interpreter main loop after performing intrinsic lowering,Brian Gaeke2004-04-231-0/+1
| | | | | | | | because 1) the first instruction might not be a call site, and 2) CS and SF.Caller were not getting set to point to the new call site anyway (resulting in a crash on e.g. call %llvm.memset). llvm-svn: 13122
