…otnet#63598) * Fix native frame unwind in syscall on arm64 for VS4Mac crash report. Add arm64 version of StepWithCompactNoEncoding for syscall leaf node wrappers that have compact encoding of 0. Fix ReadCompactEncodingRegister so it actually decrements the addr. Change StepWithCompactEncodingArm64 to match what MacOS libunwind does for framed and frameless stepping. arm64 can have frames with the same SP (but different IPs). Increment SP for this condition so createdump's unwind loop doesn't break out on the "SP not increasing" check and the frames are added to the thread frame list in the correct order. Add getting the unwind info for tail called functions like this: __ZL14PROCEndProcessPvji: 36630: f6 57 bd a9 stp x22, x21, [sp, #-48]! 36634: f4 4f 01 a9 stp x20, x19, [sp, #16] 36638: fd 7b 02 a9 stp x29, x30, [sp, #32] 3663c: fd 83 00 91 add x29, sp, #32 ... 367ac: e9 01 80 52 mov w9, #15 367b0: 7f 3e 02 71 cmp w19, dotnet#143 367b4: 20 01 88 1a csel w0, w9, w8, eq 367b8: 2e 00 00 94 bl _PROCAbort _TerminateProcess: -> 367bc: 22 00 80 52 mov w2, #1 367c0: 9c ff ff 17 b __ZL14PROCEndProcessPvji The IP (367bc) returns the (incorrect) frameless encoding with nothing on the stack (uses an incorrect LR to unwind). To fix this get the unwind info for PC -1 which points to PROCEndProcess with the correct unwind info. This matches how lldb unwinds this frame. Always address module segment to IP lookup list instead of checking the module regions. Strip pointer authentication bits on PC/LR.

This adds support for EnC on arm64. A couple of notes on the implementation compared to x64: - On x64 we get the fixed stack size from unwind info. However, for the frames we set up on arm64 for EnC it is not possible to extract the frame size from there because their prologs generally look like stp fp, lr, [sp,#-16]! mov fp, sp sub sp, sp, dotnet#144 with unwind codes like the following: set_fp; mov fp, sp save_fplr_x #1 (0x01); tp fp, lr, [sp, #-16]! As can be seen, it is not possible to get the fixed stack size from unwind info in this case. Instead we pass it through the GC info that already has a section for EnC data. - On arm64 the JIT is required to place the PSPSym at the same offset from caller-SP for both the main function and for funclets. Due to this we try to allocate the PSPSym as early as possible in the main function and we must take some care in funclets. However, this conflicts with the EnC frame header that the JIT uses to place values that must be preserved on EnC transitions. This is currently callee-saved registers and the MonitorAcquired boolean. Before this change we were allocating PSPSym above (before) the monitor acquired boolean, but we now have to allocate MonitorAcquired first, particularly because the size of the preserved header cannot change on EnC transitions, while the PSPSym can disappear or appear. This changes frame allocation slightly for synchronized functions.

These helpers are used to report names of things in warnings. The functional changes are: * For method parameters, use the parameter name if available (and only if not fallback to the #1 notation) * For property accessor methods, use the C# naming scheme, so for example Type.Property.get instead of Type.get_Property. Both of these changes are in preparation to bring NativeAOT closer in behavior to ILLink and the trim analyzers. For this I moved some of the helpers to the common shared code. Some unrelated code cleanup as well. Co-authored-by: Michal Strehovský <MichalStrehovsky@users.noreply.github.com>

E.g., Update LSRA "Allocating Registers" table description. Dump nodes added during resolution, e.g.: ``` BB29 bottom (BB08->BB08): move V25 from STK to rdi (Critical) N001 ( 1, 1) [001174] ----------z t1174 = LCL_VAR int V25 cse4 rdi REG rdi ``` Dump more data in the LSRA block sequence data: ``` -BB03( 16 ) -BB04( 4 ) +BB03 ( 16 ) critical-in critical-out +BB04 ( 4 ) critical-out ``` When dumping various flow bitvectors, annotate the bitvectors better: ``` -BB25 in gen out -0000000000000000 -0000000000000003 CSE #1.c -0000000000000003 CSE #1.c +BB25 + in: 0000000000000000 +gen: 0000000000000003 CSE #1.c +out: 0000000000000003 CSE #1.c ``` Dump hoisting bitvectors using the sorting number: ``` - USEDEF (5)={V04 V00 V01 V02 V03} + USEDEF (5)={V00 V01 V02 V03 V04} ``` Also, fix various typos and formatting.

…128163) > [!NOTE] > This PR was authored with assistance from GitHub Copilot. Fixesdotnet#128044. ## Problem createdump SIGSEGVs on Linux when generating a Heap-type minidump for a process running interpreted code. The crash reproduces locally with the `InterpreterStack` DumpTests debuggee and matches the CI failure that prompted `<DumpTypes>Full</DumpTypes>` to be added as a temporary workaround. The faulting backtrace is: ``` #0 Thread::IsAddressInStack threads.cpp:6741 #1 Thread::EnumMemoryRegionsWorker threads.cpp:6909 (calls IsAddressInStack(currentSP)) #2 Thread::EnumMemoryRegions threads.cpp #3 ThreadStore::EnumMemoryRegions #4 ClrDataAccess::EnumMemDumpAllThreadsStack #5 ClrDataAccess::EnumMemoryRegionsWorkerHeap (HEAP2-only path) ``` ## Root cause `Thread::m_pInterpThreadContext` was declared as a raw `InterpThreadContext *`. In non-DAC code that's a normal host pointer, but in DAC mode the field's value is a target-process address. When `IsAddressInStack` (a DAC-callable helper) dereferenced `m_pInterpThreadContext->pStackStart` it read from a target-process address as if it were a host address, which faults inside createdump. ## Fix Change the field type to `PTR_InterpThreadContext` (DPTR), matching the treatment of other Thread fields like `m_pFrame`. In non-DAC builds `DPTR(T)` is just `T*`, so there is no overhead or behavior change. In DAC builds the read goes through `__DPtr<T>` and marshals correctly from the target. Also remove the `<DumpTypes>Full</DumpTypes>` workaround on the `InterpreterStack` DumpTests debuggee so the Heap path that originally failed is exercised again. ## Validation Locally reproduced the original SIGSEGV on Linux x64 with the auto-dump mechanism (`DOTNET_DbgMiniDumpType=2` + `DOTNET_Interpreter=MethodA`) running the `InterpreterStack` debuggee. With this fix applied, createdump produces a complete Heap dump (~74 MB) instead of crashing. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

An Android production app reported a native abort while building an X.509 chain on arm64. The available tombstone snippet showed the process aborting in `AndroidCryptoNative_X509ChainBuild` from `pal_x509chain.c`, with the native guard reporting that parameter `ctx` was not a valid pointer. The report did not include a repro or full tombstone, but the observed failure mode means managed code reached the native build entry point with a null `X509ChainContext*`. ``` Thread /__w/1/s/src/native/libs/System.Security.Cryptography.Native.Android/pal_x509chain.c:113 (AndroidCryptoNative_X509ChainBuild): Parameter 'ctx' must be a valid pointer *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** pid: 0, tid: 31609 >>> com.app.name <<< backtrace: #00 pc 0x000000000002232c /system/lib64/libc.so (abort+116) #1 pc 0x0000000000021fe8 [removed]-KwPZdoEumri00C7kBm3pQw==/lib/arm64/libSystem.Security.Cryptography.Native.Android.so #2 pc 0x00000000000220b0 [removed]-KwPZdoEumri00C7kBm3pQw==/lib/arm64/libSystem.Security.Cryptography.Native.Android.so (AndroidCryptoNative_X509ChainBuild+88) #3 pc 0x000000000000cfcc ``` `X509ChainContext` is created by `AndroidCryptoNative_X509ChainCreateContext`. That initialization can fail if Android certificate store setup or PKIX parameter construction throws, or if required JNI global references cannot be created. Previously, the managed Android chain path stored the returned `SafeHandle` without checking whether context creation failed, so a later build could pass a null native context to `AndroidCryptoNative_X509ChainBuild` and terminate the app process. This change makes context creation fail gracefully: - The native create path checks Java exceptions around object creation and method calls more consistently. - Partial native contexts are destroyed if global-reference creation fails. - The Android interop wrapper checks the returned chain context immediately, including a null safe-handle return, and throws `CryptographicException` if initialization failed. No regression test is included because the reliable failure modes depend on Android platform/provider state or artificial fault injection, and a test hook would be fragile and not representative. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Co-authored-by: Kevin Jones <kevin@vcsjones.com>
