* Add comments to fallsthrough cases. Also, this fixes PR1492Anton Korobeynikov2007-06-031-0/+3
| | | | llvm-svn: 37405
* Check arguments & return types of main(). Abort in case of no match.Anton Korobeynikov2007-06-031-0/+32
| | | | llvm-svn: 37404
* For PR1486:Reid Spencer2007-06-012-2/+2
| | | | | | | Avoid overwriting the APInt instance with 0 bytes which causes the bitwidth to be set to 0 (illegal) producing a subsequent assert. llvm-svn: 37391
* Compute the correct word number.Zhou Sheng2007-05-241-1/+1
| | | | llvm-svn: 37322
* On Linux platforms and at optimization levels -O1 and above, llvm-gcc canReid Spencer2007-05-191-3/+14
| | | | | | | turn "putchar" calls into _IO_putc calls which is a lower-level interface. This patch allows these calls to be executed by lli in interpreter mode. llvm-svn: 37254
* Print integer values as both decimal and hexadecimal for convenienceReid Spencer2007-05-171-1/+1

* Avoid a "loss of precision" error in gcc 4.1.3.Reid Spencer2007-05-161-1/+1
| | | | llvm-svn: 37105
* Implement printing of instruction result values when debug info is turnedReid Spencer2007-05-161-0/+21
| | | | | | | on. This helps to speed up the debugging time by showing computational results as the program executes. llvm-svn: 37095
* Bitcast all the bits of a floating point value, not just one. The zeroReid Spencer2007-05-041-0/+2
| | | | | | | | extension is needed because the constructor for the Destination value causes the APInt to have a bit width of 1. Patch by Guoling Han. llvm-svn: 36733
* 1. Don't swap byte order in scanf. It isn't necessary and leads toReid Spencer2007-04-261-1/+1
| | | | | | | | 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. llvm-svn: 36482
* We only need one putchar which gives it a shot at getting matched by itsReid Spencer2007-04-211-17/+4

| | | | llvm-svn: 36286
* eliminate use of Instruction::getPrev(). Patch by Gabor Greif in 2005.Chris Lattner2007-04-171-3/+6
| | | | llvm-svn: 36198
* Implement @sext and @zext parameter attribute handling properly instead ofReid Spencer2007-04-161-11/+20
| | | | | | | forcing every small argument of every function regardless of attributes or calling convention to be expanded. llvm-svn: 36174
* For PR1293:Reid Spencer2007-03-301-49/+67
| | | | | | | | | | * 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. llvm-svn: 35508
* Unbreak C++ build.Jeff Cohen2007-03-121-0/+1
| | | | llvm-svn: 35067
* Don't use std::hex.Bill Wendling2007-03-081-1/+1
| | | | llvm-svn: 35038
* Don't use a cast. It causes an error on some platforms.Bill Wendling2007-03-081-1/+1
| | | | llvm-svn: 35037
* Fix all of last night's JIT failures in Prolangs-C++ by finishing theReid Spencer2007-03-061-42/+151
| | | | | | implementation of getConstantValue(). llvm-svn: 34988
* Implement PR1240Anton Korobeynikov2007-03-061-2/+3
| | | | llvm-svn: 34959
* 1. Make StoreValueToMemory a little more efficient by not requiring callerReid Spencer2007-03-061-2/+2
| | | | | | | | to make a copy of the GenericValue. 2. Fix a copy & paste bug in StoreValueToMemory where 64-bit values were truncated to 32 llvm-svn: 34958
* 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
* Simplify code as a result of the change in GenericValue to have a singleReid Spencer2007-03-061-28/+15
| | | | | | integer field of type APInt instead of different sized integer fields. llvm-svn: 34952
* 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
* Adjust and simplify external function processing now that GenericValue hasReid Spencer2007-03-061-33/+41
| | | | | | a single integer field of type APInt. llvm-svn: 34950
* APInt's are no longer allocated on the heap because they are directReid Spencer2007-03-061-12/+0
| | | | | | | members of GenericValue. Consequently the code to clean them up isn't needed. llvm-svn: 34948
* Remove the insufficient code in Interpreter::create that computed theReid Spencer2007-03-061-12/+0
| | | | | | | | 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". llvm-svn: 34947
* Simplify things significantly because GenericValue now has a single integerReid Spencer2007-03-061-281/+72
| | | | | | | | | 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. llvm-svn: 34946
* Remove unnecessary #include.Reid Spencer2007-03-031-1/+0
| | | | llvm-svn: 34889
* Deal with error handling better.Reid Spencer2007-03-035-14/+31
| | | | llvm-svn: 34887
* 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
* Avoid memory leakage by having caller construct the APInt for theReid Spencer2007-03-031-5/+4
| | | | | | destination value of LoadValueFromMemory. llvm-svn: 34883
* 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
* 1. Have the ExecutionContext keep track of the APInt's allocated andReid Spencer2007-03-031-11/+13
| | | | | | | ensure they are cleaned up when the stack frame exits. 2. Move a function to the Execution.cpp file where it belongs. llvm-svn: 34876
* Implement loading and storing of APInt values from memory.Reid Spencer2007-03-031-8/+16
| | | | llvm-svn: 34874
* Fix PR1216 by cleaning up the ownership of JITResolver.Chris Lattner2007-02-242-29/+42
| | | | llvm-svn: 34552
* For PR1195:Reid Spencer2007-02-151-1/+1
| | | | | | | Rename PackedType -> VectorType, ConstantPacked -> ConstantVector, and PackedTyID -> VectorTyID. No functional changes. llvm-svn: 34293
* From Dan Gohman:Chris Lattner2007-02-142-3/+3
| | | | | | | | | | 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
* Generalize TargetData strings, to support more interesting forms of data.Chris Lattner2007-02-141-1/+1
| | | | | | Patch by Scott Michel. llvm-svn: 34266
* eliminate vector-related allocationsChris Lattner2007-02-131-2/+2

* eliminate use of TargetData::getIndexedOffset that takes a vectorChris Lattner2007-02-101-2/+3

* For PR1188:Reid Spencer2007-02-082-2/+2
| | | | | | | | Compute BitMask correctly. Patch by Leo (wenwenti@hotmail.com). llvm-svn: 34026
* For PR411:Reid Spencer2007-02-051-1/+1
| | | | | | | | Adjust to changes in Module interface: getMainFunction() -> getFunction("main") getNamedFunction(X) -> getFunction(X) llvm-svn: 33922
* Changes to support making the shift instructions be true BinaryOperators.Reid Spencer2007-02-022-6/+7
| | | | | | | | | | | | 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 Spencer2007-01-304-10/+10
| | | | | | confusion with external linkage types. llvm-svn: 33663
