2007-03-06Fix some thinko's in the last patch. PtrSize has to be in bits and weReid Spencer
might need to zext not just trunc the value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34955 91177308-0d34-0410-b5e6-96231b3b80d8
2007-03-06Fix a bug in IntToPtr. Truncating to 64-bits only works if the integerReid Spencer
is larger. Adjust so that it truncates to pointer width, only if necessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34954 91177308-0d34-0410-b5e6-96231b3b80d8
2007-03-06Radically simplify execution. This patch gets rid of all the specialReid Spencer
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34951 91177308-0d34-0410-b5e6-96231b3b80d8

2007-03-06APInt's are no longer allocated on the heap because they are directReid Spencer
members of GenericValue. Consequently the code to clean them up isn't needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34948 91177308-0d34-0410-b5e6-96231b3b80d8
2007-03-06Remove the insufficient code in Interpreter::create that computed theReid Spencer
Target DataLayout incorrectly. For now, we'll trust that the module has got the correct DataLayout. In the future, this needs to be changed to tell the TargetData to be "current host". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34947 91177308-0d34-0410-b5e6-96231b3b80d8

2007-02-14From Dan Gohman:Chris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34267 91177308-0d34-0410-b5e6-96231b3b80d8

2007-02-02Changes to support making the shift instructions be true BinaryOperators.Reid Spencer
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33776 91177308-0d34-0410-b5e6-96231b3b80d8

2007-01-20Implement the signed icmp instructions properly. To do this we introduceReid Spencer
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33403 91177308-0d34-0410-b5e6-96231b3b80d8

2007-01-15rename Type::isIntegral to Type::isInteger, eliminating the old Type::isInteger.Chris Lattner
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! :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33225 91177308-0d34-0410-b5e6-96231b3b80d8

2007-01-12For PR1064:Reid Spencer
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33113 91177308-0d34-0410-b5e6-96231b3b80d8
