2020-06-17Implement instantiating and unboxing through portable stublinker code… (#106)JUNG DONG-HEON41-2407/+746
* 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
2020-06-17Fix GenerateShuffleArray to support cyclic shuffles (dotnet/coreclr#26169)JUNG DONG-HEON4-20/+182
* Fix GenerateShuffleArray to support cyclic shuffles The GenerateShuffleArray was not handling case when there was a cycle in the register / stack slots shuffle and it resulted in an infinite loop in this function. This issue is Unix Amd64 ABI specific. To fix that, this change reworks the algorithm completely. Besides fixing the issue, it has also better performance in some cases. To fix the cyclic shuffling, I needed an extra helper register. However, there was no available general purpose register available, so I had to use xmm8 for this purpose. * Remove special handling of the hang from ABI stress
2020-06-04[x86/Linux] Fix SIGSEGV during evaluation abort routine.submit/tizen_5.5/20200607.233848submit/tizen/20200607.233857accepted/tizen/unified/20200608.144754accepted/tizen/5.5/unified/20200608.142150Mikhail Kurinnoi1-1/+16
In case of evaluation with implicit function call aborted by ```ICorDebugEval::Abort()```, CoreCLR crash with SIGSEGV at line since ```m_pJM``` is ```NULL```. This happens because during ```EECodeInfo::Init()``` call, ```codeAddress``` parameter provide address inside native code region (this address belong to CallDescrWorkerInternal(),, but not address inside managed code, so, ```ExecutionManager::FindCodeRange()``` can't find appropriate ```RangeSection```. During investigation I found, that at line current context was not changed properly (we have wrong ```Eip``` register value). I found, that ```FuncEvalFrame::UpdateRegDisplay()``` code don't have x86/Linux support implemented. I propose changes, that were already made for other ```UpdateRegDisplay()``` implementations in order to provide proper context for x86/Linux.
2020-06-04[Tizen] Enable ASan annotation of passing to native code buffersAndrey Kazmin2-3/+47
Turn on ASan inteceptors while marshaling managed buffers to native code. We could not properly annotate already allocated on heap buffers, so we have to disable pinning of such objects. Current patch affects only pinning of native arrays.

2020-04-15Fix PIE options (#26323)submit/tizen/20200415.223728accepted/tizen/unified/20200416.080052Jan Vorlicek43-121/+0
* Fix PIE options We were missing passing the -pie linker option. That means that while we were compiling our code as position independent, the executables (not shared libraries) were not marked as position independent and ASLR was not applied to them. They were always loaded to fixed addresses. This change adds the missing -pie option and also replaces all the individual settings of -fPIE / -fPIC on the targets we build by a centralized setting of CMAKE_POSITION_INDEPENDENT_CODE variable that causes cmake to add the appropriate compiler options everywhere. * Fix native parts of coreclr tests build The native parts of the tests are not built using the root CMakeLists.txt so I am moving enabling the position independent code to configurecompiler.cmake Change-Id: Ieafff8984ec23e5fdb00fb0c2fb017e53afbce88
2020-03-25[Tizen] Add FEATURE_LARGEADDRESS_SUPPORTSangwook Kim3-0/+13
Many diagnostic tools are unaware of 32-bit applications which have large address spaces (> 2GB). Such tools include the TraceEvent library (required by PerfView and dotnet-trace), and Visual Studio. They assume the address range 0x80000000 through 0xFFFFFFFF as the system space and thus often fail to read symbols from event traces generated by CoreCLR. This workaround is to support such scenarios by simply discarding MSBs of 32-bit instruction pointer values in the trace output. Only a minimal set of values required for symbol resolution are affected by this change. Beware that you will have to manually restore the original values when you inspect them in lldb or etc.

2020-03-25Change bIsFree check in DacValidateMethodTable (#1086)Dong-Heon Jung1-8/+1
Some commands of SOS validate a method table in DacValidateMethodTable. In the function, it checks whether a method table is FreeObjectMethodTable or not with GetClass() value. However, GetClass() should not be NULL. (There is an assert in GetClass()) In this patch, it compares pMT address with g_pFreeObjectMethodTable address only.

2020-03-25Handle glibc sys/sysctl.h deprecation (#27048)Omair Majid1-2/+5
glibc has deprecated sys/sysctl.h: In file included from /coreclr/src/pal/src/misc/sysinfo.cpp:32: /usr/include/sys/sysctl.h:21:2: error: "The <sys/sysctl.h> header is deprecated and will be removed." [-Werror,-W#warnings] #warning "The <sys/sysctl.h> header is deprecated and will be removed." ^ 1 error generated. Fix that by preferring sysconf and only including sys/sysctl.h if HAVE_SYSCONF is not true. This mirrors the order of the implementation code in this file (sysinfo.cpp) which checks for HAVE_SYSCONF before HAVE_SYSCTL. Fixes #27008
2020-03-25Enable NGEN for methods marked with AggressiveOptimization (#27259)Dong-Heon Jung1-1/+4
- Methods marked with AggressiveOptimization are not NGENed at all. - The methods are compiled during the runtime with high JITC overhead. - It makes launching time slower over 6% in our embedded systems.

2020-03-25[Tizen] Implement ASan wrapper for Linux ARM32Vyacheslav Cherkashin6-0/+278
This commit implements wrappers that allow interception transitions from managed to external unmanaged code (CIL -> native) and back (native -> CIL). This allows enable/disable ASan during transitions. Due to this, we sanitize only external code, which allows us to achieve acceptable performance.

2020-03-25[Tizen] skip dotnet specific arguments in corerunKonstantin Baladurin1-0/+13
Now we use corerun to run corefx tests instead of dotnet, because last one isn't available for Tizen/armel. So we need to skip dotnet specific arguments, we patch corerun for it because Microsoft.DotNet.RemoteExecutor tries to execute binary that it gets from /proc/self/maps, so we need a binary that will behave like dotnet.
