2009-09-23Make EngineBuilder return more error codes, by KS Sreeram.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82600 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-23just remove interpreter support for endianness mismatches. This wasChris Lattner
really old code from when we were running sparcv9 bc files on x86 (before I ported llvm-gcc 3 to work on x86) :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79871 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78948 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-07To catch bugs like the one fixed inJeffrey Yasskin
http://llvm.org/viewvc/llvm-project?view=rev&revision=78127, I'm changing the ExecutionEngine's global mappings to hold AssertingVH<const GlobalValue>. That way, if unregistering a mapping fails to actually unregister it, we'll get an assert. Running the jit nightly tests didn't uncover any actual instances of the problem. This also uncovered the fact that AssertingVH<const X> didn't work, so I fixed that too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78400 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-04Make ExecutionEngine::updateGlobalMapping(GV, NULL) properly remove GV's oldJeffrey Yasskin
address from the reverse mapping, and add a test that this works now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78127 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-18Add EngineBuilder to ExecutionEngine in favor of the five optional argument ↵Reid Kleckner
EE::create(). Also a test commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76276 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-14llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin
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"). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75640 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-11assert(0) -> LLVM_UNREACHABLE.Torok Edwin
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75379 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-11Convert more assert(0)+abort() -> LLVM_UNREACHABLE,Torok Edwin
and abort()/exit() -> llvm_report_error(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75363 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-08Add an option to allocate JITed global data separately from code. ByJeffrey Yasskin
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! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75059 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-07Introduce new error handling API.Torok Edwin
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74922 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Split the Add, Sub, and Mul instruction opcodes into separateDan Gohman
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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72897 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-09Rename PaddedSize to AllocSize, in the hope that thisDuncan Sands
will make it more obvious what it represents, and stop it being confused with the StoreSize. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71349 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-29Instead of passing in an unsigned value for the optimization level, use an enum,Bill Wendling
which better identifies what the optimization is doing. And is more flexible for future uses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70440 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-29The second part of the change from -fast to -O#. This changes the JIT to acceptBill Wendling
an optimization level instead of a simple boolean telling it to generate code "fast" or the other type of "fast". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70347 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-24fix one more fp80 case (used only by Interpreter)Dale Johannesen
and streamline code here a bit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67636 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-24Change JIT for different layout of fp80.Dale Johannesen
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67629 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-18Add support to the JIT for true non-lazy operation. When a call to a functionNate Begeman
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64906 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-23Add support for deleting a module provider from a JIT in such a way that it ↵Nate Begeman
does not cause the owned module to be fully materialized. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62864 91177308-0d34-0410-b5e6-96231b3b80d8

suggested by Chris. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62099 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-25Support for allocation of TLS variables in the JIT. Allocation of a globalNicolas Geoffray
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58142 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54523 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-07Rewrite JIT handling of GlobalVariables so theyDale Johannesen
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54442 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52414 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-21Fix a couple issues with the JIT and multiple modules:Nate Begeman
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51384 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-20Fix ExecutionEngine's constant code to work properly when structs and arraysDan Gohman

2008-05-14Add CommonLinkage; currently tentative definitionsDale Johannesen
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51118 91177308-0d34-0410-b5e6-96231b3b80d8
