2007-04-261. Don't swap byte order in scanf. It isn't necessary and leads toReid Spencer
incorrect results (canonicalization was dropped several commits ago). 2. Add support for fscanf. 3. Suppress a warning about cast to pointer from non-pointer-sized integer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@36482 91177308-0d34-0410-b5e6-96231b3b80d8

2007-03-30For PR1293:Reid Spencer
* Rename the FunctionType* parameter from M to FT on all the functions. * Implement a fix for PR1293 by just asserting that library functions that must return pointers should have pointer typed results. This just makes sure that we don't attempt to use an uninitialized integer or something later on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35508 91177308-0d34-0410-b5e6-96231b3b80d8

2007-03-061. Make StoreValueToMemory a little more efficient by not requiring callerReid Spencer
to make a copy of the GenericValue. 2. Fix a copy & paste bug in StoreValueToMemory where 64-bit values were truncated to 32 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34958 91177308-0d34-0410-b5e6-96231b3b80d8
2007-03-06Fix some thinko's in the last patch. PtrSize has to be in bits and weReid Spencer

2007-03-06Simplify code as a result of the change in GenericValue to have a singleReid Spencer

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
2007-03-06Simplify things significantly because GenericValue now has a single integerReid Spencer
field, of type APInt, instead of multiple integer fields. Also, get rid of the special endianness code in StoreValueToMemory and LoadValueToMemory. ExecutionEngine is always used to execute on the host platform so this is now unnecessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34946 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
