* llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Edwin Török2009-07-141-9/+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"). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75640 91177308-0d34-0410-b5e6-96231b3b80d8
* assert(0) -> LLVM_UNREACHABLE.Edwin Török2009-07-111-6/+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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75379 91177308-0d34-0410-b5e6-96231b3b80d8

* Introduce new error handling API.Edwin Török2009-07-071-4/+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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74922 91177308-0d34-0410-b5e6-96231b3b80d8

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.

* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64906 91177308-0d34-0410-b5e6-96231b3b80d8

* 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.

* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51384 91177308-0d34-0410-b5e6-96231b3b80d8
