* Instead of passing in an unsigned value for the optimization level, use an enum,Bill Wendling2009-04-293-9/+12
| | | | | | | 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 Wendling2009-04-293-13/+13
| | | | | | | an optimization level instead of a simple boolean telling it to generate code "fast" or the other type of "fast". llvm-svn: 70347
* Under unusual circumstances (jitting a function that causes the creation ofNick Lewycky2009-04-271-17/+23
| | | | | | | | | | | | another stub, but then never calling the jitted function) can cause the JIT to leave a stub in place. Judging by the comments this is a known deficiency, so we're just not going to use AssertingVH for the StubToFunctionTy map. Also shorten some lines longer than 80 columns. This fixes the "make check" failure with ocaml on x86-64 linux. llvm-svn: 70185
* Use an AssertingVH to detect the case where the Function was deleted butNick Lewycky2009-04-191-10/+11

* make sure to unlock keymgr if the JIT is created and destroyed, allChris Lattner2009-04-161-5/+3
| | | | | | | | locks must be matched with unlocks. Also, use calloc to allocate the block so that it is properly zero'd. Thanks to Nick Kledzik for tracking this down. llvm-svn: 69314
* Mac OS X 10.6 and above do not use key manager to register EH frames.Evan Cheng2009-04-141-2/+8

* Use CHAR_BIT instead of hard-coding 8 in several places where itDan Gohman2009-04-011-1/+2

* Fix some significant problems with constant pools that resulted in ↵Evan Cheng2009-03-131-23/+35
| | | | | | | | | | | | | | | | | | | | | | | unnecessary paddings between constant pool entries, larger than necessary alignments (e.g. 8 byte alignment for .literal4 sections), and potentially other issues. 1. ConstantPoolSDNode alignment field is log2 value of the alignment requirement. This is not consistent with other SDNode variants. 2. MachineConstantPool alignment field is also a log2 value. 3. However, some places are creating ConstantPoolSDNode with alignment value rather than log2 values. This creates entries with artificially large alignments, e.g. 256 for SSE vector values. 4. Constant pool entry offsets are computed when they are created. However, asm printer group them by sections. That means the offsets are no longer valid. However, asm printer uses them to determine size of padding between entries. 5. Asm printer uses expensive data structure multimap to track constant pool entries by sections. 6. Asm printer iterate over SmallPtrSet when it's emitting constant pool entries. This is non-deterministic. Solutions: 1. ConstantPoolSDNode alignment field is changed to keep non-log2 value. 2. MachineConstantPool alignment field is also changed to keep non-log2 value. 3. Functions that create ConstantPool nodes are passing in non-log2 alignments. 4. MachineConstantPoolEntry no longer keeps an offset field. It's replaced with an alignment field. Offsets are not computed when constant pool entries are created. They are computed on the fly in asm printer and JIT. 5. Asm printer uses cheaper data structure to group constant pool entries. 6. Asm printer compute entry offsets after grouping is done. 7. Change JIT code to compute entry offsets on the fly. llvm-svn: 66875
* Allow cross-process JIT to handle MachineRelocations of the ExternalSymbolNate Begeman2009-03-111-13/+82

* Fix PR3724 by searching for the largest free block when Chris Lattner2009-03-091-2/+19
| | | | | | | | | allocating memory in the JIT. This is insanely inefficient, but hey, most people implement their own memory managers anyway. Patch by Eric Yew! llvm-svn: 66472
* Introduce new linkage types linkonce_odr, weak_odr, common_odrDuncan Sands2009-03-071-2/+2
| | | | | | | | | | | | | | | | | | | | | and extern_weak_odr. These are the same as the non-odr versions, except that they indicate that the global will only be overridden by an *equivalent* global. In C, a function with weak linkage can be overridden by a function which behaves completely differently. This means that IP passes have to skip weak functions, since any deductions made from the function definition might be wrong, since the definition could be replaced by something completely different at link time. This is not allowed in C++, thanks to the ODR (One-Definition-Rule): if a function is replaced by another at link-time, then the new function must be the same as the original function. If a language knows that a function or other global can only be overridden by an equivalent global, it can give it the weak_odr linkage type, and the optimizers will understand that it is alright to make deductions based on the function body. The code generators on the other hand map weak and weak_odr linkage to the same thing. llvm-svn: 66339
* Finish cross-process JIT work, and clean up previous work.Nate Begeman2009-03-072-30/+40
| | | | | | | | | | | | | | | | 1. When the JIT is asked to remove a function, updating it's mapping to 0, we invalidate any function stubs used only by that function. Now, also invalidate the JIT's mapping from the GV the stub pointed to, to the address of the GV. 2. When dlsym stubs for cross-process JIT are enabled, do not abort just because a named function cannot be found in the JIT's process. 3. Fix various assumptions about when it is ok to use the lazy resolver when non-lazy JITing is enabled. llvm-svn: 66324

* When allocating stubs, keep track of which Functions are referencing the stub.Nate Begeman2009-03-051-17/+120
| | | | | | | | This invalidates the stubs in the resolver map when they are no longer referenced, and should the JIT memory manager ever pick up a deallocateStub interface, the JIT could reclaim the memory for unused stubs as well. llvm-svn: 66141
* Fix a thinko in the JIT where the address of a GV was only recorded in the mapNate Begeman2009-03-042-6/+16
| | | | | | | | | on failure to resolve it. Do not abort on failure to resolve an external symbol when using dlsym stubs, since the symbol may not be in the JIT's address space. Just use 0. Allow dlsym stubs to differentiate between GlobalVars and Functions. llvm-svn: 66050
* don't #include a header into the middle of an anon namespace.Chris Lattner2009-03-031-7/+5

* Add support to the JIT for true non-lazy operation. When a call to a functionNate Begeman2009-02-184-40/+224
| | | | | | | | | | | | | | | | | | | | 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

* Split the locking out of JIT::runJITOnFunction so that callersDan Gohman2009-02-062-5/+9

* Change isGVCompilationDisabled() semantics again. It should abort on any GV ↵Evan Cheng2009-01-161-1/+4
| | | | | | that's not constant whether it's "internal" or not. In a server / client environment, GV is returned in the same block of memory as code. However, the memory might not be writable. llvm-svn: 62336
* Registry.h should not depend on CommandLine.h.Mikhail Glushenkov2009-01-161-1/+2

* Always emit a function pointer as a pointer to the function stub (if there ↵Evan Cheng2008-11-131-1/+20
