* Simplify / normalize some uses of Value::getName.Daniel Dunbar2009-07-211-1/+1
| | | | llvm-svn: 76553
* Add EngineBuilder to ExecutionEngine in favor of the five optional argument ↵Reid Kleckner2009-07-181-13/+52
| | | | | | | | EE::create(). Also a test commit. llvm-svn: 76276
* llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin2009-07-141-9/+9
| | | | | | | | | This adds location info for all llvm_unreachable calls (which is a macro now) in !NDEBUG builds. In NDEBUG builds location info and the message is off (it only prints "UREACHABLE executed"). llvm-svn: 75640
* assert(0) -> LLVM_UNREACHABLE.Torok Edwin2009-07-111-6/+6
| | | | | | | | | Make llvm_unreachable take an optional string, thus moving the cerr<< out of line. LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for NDEBUG builds. llvm-svn: 75379
* Convert more assert(0)+abort() -> LLVM_UNREACHABLE,Torok Edwin2009-07-111-19/+21
| | | | | | and abort()/exit() -> llvm_report_error(). llvm-svn: 75363
* Add an option to allocate JITed global data separately from code. ByJeffrey Yasskin2009-07-081-3/+4
| | | | | | | | | | | | | | default, this option is not enabled to support clients who rely on this behavior. Fixes http://llvm.org/PR4483 A patch to allocate additional memory for globals after we run out is forthcoming. Patch by Reid Kleckner! llvm-svn: 75059
* Introduce new error handling API.Torok Edwin2009-07-071-4/+4
| | | | | | | | This will replace exit()/abort() style error handling with an API that allows clients to register custom error handling hooks. The default is to call exit(1) when no error handler is provided. llvm-svn: 74922
* Split the Add, Sub, and Mul instruction opcodes into separateDan Gohman2009-06-041-9/+12
| | | | | | | | | | | | | | | integer and floating-point opcodes, introducing FAdd, FSub, and FMul. For now, the AsmParser, BitcodeReader, and IRBuilder all preserve backwards compatability, and the Core LLVM APIs preserve backwards compatibility for IR producers. Most front-ends won't need to change immediately. This implements the first step of the plan outlined here: http://nondot.org/sabre/LLVMNotes/IntegerOverflow.txt llvm-svn: 72897
* Rename PaddedSize to AllocSize, in the hope that thisDuncan Sands2009-05-091-5/+5
| | | | | | | will make it more obvious what it represents, and stop it being confused with the StoreSize. llvm-svn: 71349
* Instead of passing in an unsigned value for the optimization level, use an enum,Bill Wendling2009-04-291-1/+1
| | | | | | | which better identifies what the optimization is doing. And is more flexible for future uses. llvm-svn: 70440
* The second part of the change from -fast to -O#. This changes the JIT to acceptBill Wendling2009-04-291-3/+3
| | | | | | | an optimization level instead of a simple boolean telling it to generate code "fast" or the other type of "fast". llvm-svn: 70347
* fix one more fp80 case (used only by Interpreter)Dale Johannesen2009-03-241-21/+5
| | | | | | and streamline code here a bit. llvm-svn: 67636
* Change JIT for different layout of fp80.Dale Johannesen2009-03-241-5/+5
| | | | llvm-svn: 67629
* Add support to the JIT for true non-lazy operation. When a call to a functionNate Begeman2009-02-181-0/+1
| | | | | | | | | | | | | | | | | | | | that has not been JIT'd yet, the callee is put on a list of pending functions to JIT. The call is directed through a stub, which is updated with the address of the function after it has been JIT'd. A new interface for allocating and updating empty stubs is provided. Add support for removing the ModuleProvider the JIT was created with, which would otherwise invalidate the JIT's PassManager, which is initialized with the ModuleProvider's Module. Add support under a new ExecutionEngine flag for emitting the infomration necessary to update Function and GlobalVariable stubs after JITing them, by recording the address of the stub and the name of the GlobalValue. This allows code to be copied from one address space to another, where libraries may live at different virtual addresses, and have the stubs updated with their new correct target addresses. llvm-svn: 64906
* allow main to have any integer type.Chris Lattner2009-02-041-1/+1
| | | | llvm-svn: 63743
* Add support for deleting a module provider from a JIT in such a way that it ↵Nate Begeman2009-01-231-1/+19

* Support for allocation of TLS variables in the JIT. Allocation of a globalNicolas Geoffray2008-10-251-12/+15
| | | | | | | | variable is moved to the execution engine. The JIT calls the TargetJITInfo to allocate thread local storage. Currently, only linux/x86 knows how to allocate thread local global variables. llvm-svn: 58142

* Add a "loses information" return value to APFloat::convertDale Johannesen2008-10-091-1/+2
| | | | | | | and APFloat::convertToInteger. Restore return value to IEEE754. Adjust all users accordingly. llvm-svn: 57329
* Rename APFloat::convertToAPInt to bitcastToAPInt toDale Johannesen2008-10-091-8/+8
| | | | | | | make it clearer what the function does. No functional change. llvm-svn: 57325

* Avoid a warning about isTargetNullPtr being unused in release builds.Dan Gohman2008-08-261-0/+2

* Add new parameter Fast to createJIT to enable the fast codegen path.Evan Cheng2008-08-081-3/+4
| | | | llvm-svn: 54523
* Rewrite JIT handling of GlobalVariables so theyDale Johannesen2008-08-071-0/+2
| | | | | | | | | | | | | | are allocated in the same buffer as the code, jump tables, etc. The default JIT memory manager does not handle buffer overflow well. I didn't introduce this and I'm not attempting to fix it here, but it is more likely to be hit now since we're putting more stuff in the buffer. This affects one test that I know of so far, MultiSource/Benchmarks/NPB-serial/is. llvm-svn: 54442
* Don't forget to initialize SymbolSearchingDisabled.Evan Cheng2008-06-171-0/+1
| | | | llvm-svn: 52414
* Fix a couple issues with the JIT and multiple modules:Nate Begeman2008-05-211-0/+17
| | | | | | | | | | | | 1. The "JITState" object creates a PassManager with the ModuleProvider that the jit is created with. If the ModuleProvider is removed and deleted, the PassManager is invalid. 2. The Global maps in the JIT were not invalidated with a ModuleProvider was removed. This could lead to a case where the Module would be freed, and a new Module with Globals at the same addresses could return invalid results. llvm-svn: 51384
* Fix ExecutionEngine's constant code to work properly when structs and arraysDan Gohman2008-05-201-17/+8
| | | | | | will become first-class types. llvm-svn: 51293
* Add CommonLinkage; currently tentative definitionsDale Johannesen2008-05-141-1/+1
| | | | | | | | | | are represented as "weak", but there are subtle differences in some cases on Darwin, so we need both. The intent is that "common" will behave identically to "weak" unless somebody changes their target to do something else. No functional change as yet. llvm-svn: 51118
* Make ExecutionEngine::updateGlobalMapping return the old mapping.Chris Lattner2008-04-041-5/+18

* Change the PointerType api for creating pointer types. The old functionality ↵Christopher Lamb2007-12-171-2/+3
| | | | | | of PointerType::get() has become PointerType::getUnqual(), which returns a pointer in the generic address space. The new prototype of PointerType::get() requires both a type and an address space. llvm-svn: 45082
* These are more correctly called signaling NaNs.Duncan Sands2007-12-151-1/+1

* Teach the interpreter to read and write memory in theDuncan Sands2007-12-141-59/+94
| | | | | | | | | | endianness of the target not of the host. Done by the simple expedient of reversing bytes for primitive types if the host and target endianness don't match. This is correct for integer and pointer types. I don't know if it is correct for floating point types. llvm-svn: 45039
* Remove host endianness info from TargetData andDuncan Sands2007-12-121-2/+3
| | | | | | | | put it in a new header System/Host.h instead. Instead of getting the endianness from configure, calculate it directly. llvm-svn: 44959
* Fix PR1836: in the interpreter, read and write apintsDuncan Sands2007-12-101-24/+47
| | | | | | | | | | | | | | | | using the minimum possible number of bytes. For little endian targets run on little endian machines, apints are stored in memory from LSB to MSB as before. For big endian targets on big endian machines they are stored from MSB to LSB which wasn't always the case before (if the target and host endianness doesn't match values are stored according to the host's endianness). Doing this requires knowing the endianness of the host, which is determined when configuring - thanks go to Anton for this. Only having access to little endian machines I was unable to properly test the big endian part, which is also the most complicated... llvm-svn: 44796
