2020-06-18Implement instantiating and unboxing through portable stublinker code… (#106)JUNG DONG-HEON1-12/+55
* Implement instantiating and unboxing through portable stublinker code - Handle only the cases with register to register moves - Shares abi processing logic with delegate shuffle thunk creation - Architecture specific logic is relatively simple - Do not permit use of HELPERREG in computed instantiating stubs - Fix GetArgLoc such that it works on all architectures and OS combinations Add a JIT stress test case for testing all of the various combinations - Use the same calling convention test architecture that was used as part of tail call work Rename secure delegates to wrapper delegates - Secure delegates are no longer a feature of the runtime - But the wrapper delegate lives on as a workaround for a weird detail of the ARM32 abi

2016-06-21Generic dictionary minor performance improvement and simplification for R2R ↵Fadi Hanna1-7/+17
(#5690) A set of refactoring changes to slighly improve the performance of generic dictionary access on R2R images, and simplifying the codebase: 1) Removing dependency on CEEInfo::ComputeRuntimeLookupForSharedGenericTokenStatic (and deleting the API). 2) Stop parsing the generic type/method signatures when generating the R2R dictionary lookup assembly stub. 3) Avoid re-encoding the generic type/method signatures in a new in-memory blob using a SigBuilder (signatures used directly from the R2R image) 4) Moved the parsing/loading of type/method signatures to Dictionary::PopulateEntry() 5) Dictionary index and slot number are now encoded in the generated assembly stub instead of the signature (stub takes a pointer to a data blob, which contains the signature, the dictionary index and slot, and the module pointer)

2016-06-09ARM64: Don't track LR as part of NV-ContextSwaroop Sridhar1-8/+6
The _pc and _sp fields actually refer to the caller's PC and SP values. So, remove read/writes of LR in captureX19_X29 array of ARM64 MachState. This change fixes a buffer overflow problem.

ARM64: Enabling Crossgen End-to-End Mscorlib
2016-04-29ARM64: Enabling Crossgen End-to-End MscorlibKyungwoo Lee1-7/+0
Fixes https://github.com/dotnet/coreclr/issues/4350 Fixes https://github.com/dotnet/coreclr/issues/4615 This is a bit large change across VM/Zap/JIT to properly support crossgen scenario. 1. Fix incorrect `ldr` encoding with size. 2. Enforce JIT data following JIT code per method by allocating them together. This guarantees correct PC-relative encoding for such constant data access without fix-up. 3. For the general fix-up data acceess, use `adrp/add` instruction pairs with fix-ups. Two more relocations types are implemented in all sides. 4. Interface dispatch stub is now implemented which is needed for interface call for crossgen. I've verified hello world runs with mscorlib.ni.dll.

2016-04-12Implement software write watch and make concurrent GC functional outside WindowsKoundinya Veluri1-2/+2
- Implemented software write watch using write barriers - A new set of write barriers is introduced, each corresponding to an existing one, but which also updates the write watch table. The GC switches to a write watch barrier during concurrent GC, and switches back to a non write watch barrier after the final query for dirty pages. - The write watch table is alloacted along with the card table - Since the card table is used differently, different synchonization is used for the write watch table. The runtime is suspended during resize since that is the most infrequently occuring operation, of that, ResetWriteWatch, and GetWriteWatch. - ResetWriteWatch() doesn't need a suspend, but since the software WW version is much faster than the Windows version, moved it into the suspended region to avoid some synchronization that would otherwise be required - The background calls to GetWriteWatch() don't need or do a suspend. They only need to synchronize with the resize path, not for the purpose of correct functionality, but to not miss dirty pages such that concurrent GC is effective. Miscellaneous: - Fixed runtests.sh to copy mscorlib.dll and delete the Windows version of mscorlib.ni.dll
