…lyExplicitLocals pass
Extends DWARF expression larguage to express locals/globals locations. (via

The WebAssemblyExplicitLocals can replace virtual registers to target-index()
operand type at the time when WebAssembly backend introduces local.{get,set,tee}
instead of corresponding virtual registers.

Thanks @yurydelendik! Is this WIP b/c you still want to test it a bit? As before we're probably not really capable of reviewing this, but it seems low-risk to other targets so is fine for us to carry |
The review on LLVM side is still pending for first commit. And second commit depends on first one. WIP is cause I don't want fully commit until the first commit is landed on the LLVM trunk. |
|
@yurydelendik Feel free to send a weekly "ping" on the review if there has been no activity. |
|
To clarify, is this WIP in the sense that it shouldn't land here yet, or WIP to note that it's still in the works for upstream LLVM but should still land here? |

changed the title
I'll change the title to reflect that it shall still land here -- not sure how to indicate that it is a subject for change in the future. |

Update src/llvm-project to include rust-lang/llvm-project#27. See rust-lang/llvm-project#27, which works around rust-lang/llvm-project#20 (comment) (where I stumbled over some UB in DWARF emission for WASM, resulting in non-deterministic output). r? @alexcrichton cc @yurydelendik

When `Target::GetEntryPointAddress()` calls `exe_module->GetObjectFile()->GetEntryPointAddress()`, and the returned `entry_addr` is valid, it can immediately be returned. However, just before that, an `llvm::Error` value has been setup, but in this case it is not consumed before returning, like is done further below in the function. In https://bugs.freebsd.org/248745 we got a bug report for this, where a very simple test case aborts and dumps core: ``` * thread #1, name = 'testcase', stop reason = breakpoint 1.1 frame #0: 0x00000000002018d4 testcase`main(argc=1, argv=0x00007fffffffea18) at testcase.c:3:5 1 int main(int argc, char *argv[]) 2 { -> 3 return 0; 4 } (lldb) p argc Program aborted due to an unhandled Error: Error value was Success.

CXXDeductionGuideDecl with a local typedef has its own copy of the
TypedefDecl with the CXXDeductionGuideDecl as the DeclContext of that
TypedefDecl.
```
template <typename T> struct A {
typedef T U;
A(U, T);
};
A a{(int)0, (int)0};
```
Related discussion on cfe-dev:
http://lists.llvm.org/pipermail/cfe-dev/2020-November/067252.html
Without this fix, when we import the CXXDeductionGuideDecl (via
VisitFunctionDecl) then before creating the Decl we must import the
FunctionType. However, the first parameter's type is the afore mentioned
local typedef. So, we then start importing the TypedefDecl whose
DeclContext is the CXXDeductionGuideDecl itself. The infinite loop is
formed.

The fix is to first create the TypedefDecl and only then start to import
the DeclContext.
Basically, we could do this during the import of all other Decls (not
just for typedefs). But it seems, there is only one another AST
construct that has a similar cycle: a struct defined as a function
parameter:
```
int struct_in_proto(struct data_t{int a;int b;} *d);
```
In that case, however, we had decided to return simply with an error
back then because that seemed to be a very rare construct.

After rG47321c311bdbe0145b9bf45d822185c37b19fa50 we promote vXi8 reductions to vXi16 to create a much faster PMULLW mul reduction, followed by a (free) truncation. This avoids the high cost of repeated vXi8 multiplications (which extend+multiply+truncate to/from vXi16 types....). Fixes the missing vXi8 mul reduction vectorization in PR42674 (Comment rust-lang#20) 'mul16' test case.

Although THREADLOCAL variables are supported on Darwin they cannot be used very early on during process init (before dyld has set it up). Unfortunately the checked lock is used before dyld has setup TLS leading to an abort call (`_tlv_boostrap()` is never supposed to be called at runtime). To avoid this problem `SANITIZER_CHECK_DEADLOCKS` is now disabled on Darwin platforms. This fixes running TSan tests (an possibly other Sanitizers) when `COMPILER_RT_DEBUG=ON`. For reference the crashing backtrace looks like this: ``` * thread #1, stop reason = signal SIGABRT * frame #0: 0x00000002044da0ae dyld`__abort_with_payload + 10 frame #1: 0x00000002044f01af dyld`abort_with_payload_wrapper_internal + 80 frame rust-lang#2: 0x00000002044f01e1 dyld`abort_with_payload + 9 frame rust-lang#3: 0x000000010c989060 dyld_sim`abort_with_payload + 26 frame rust-lang#4: 0x000000010c94908b dyld_sim`dyld4::halt(char const*) + 375 frame rust-lang#5: 0x000000010c988f5c dyld_sim`abort + 16 frame rust-lang#6: 0x000000010c96104f dyld_sim`dyld4::APIs::_tlv_bootstrap() + 9 frame rust-lang#7: 0x000000010cd8d6d2 libclang_rt.tsan_iossim_dynamic.dylib`__sanitizer::CheckedMutex::LockImpl(this=<unavailable>, pc=<unavailable>) at sanitizer_mutex.cpp:218:58 [opt] frame rust-lang#8: 0x000000010cd8a0f7 libclang_rt.tsan_iossim_dynamic.dylib`__sanitizer::Mutex::Lock() [inlined] __sanitizer::CheckedMutex::Lock(this=0x000000010d733c90) at sanitizer_mutex.h:124:5 [opt] frame rust-lang#9: 0x000000010cd8a0ee libclang_rt.tsan_iossim_dynamic.dylib`__sanitizer::Mutex::Lock(this=0x000000010d733c90) at sanitizer_mutex.h:162:19 [opt] frame rust-lang#10: 0x000000010cd8a0bf libclang_rt.tsan_iossim_dynamic.dylib`__sanitizer::GenericScopedLock<__sanitizer::Mutex>::GenericScopedLock(this=0x000000030c7479a8, mu=<unavailable>) at sanitizer_mutex.h:364:10 [opt] frame rust-lang#11: 0x000000010cd89819 libclang_rt.tsan_iossim_dynamic.dylib`__sanitizer::GenericScopedLock<__sanitizer::Mutex>::GenericScopedLock(this=0x000000030c7479a8, mu=<unavailable>) at sanitizer_mutex.h:363:67 [opt] frame rust-lang#12: 0x000000010cd8985b libclang_rt.tsan_iossim_dynamic.dylib`__sanitizer::LibIgnore::OnLibraryLoaded(this=0x000000010d72f480, name=0x0000000000000000) at sanitizer_libignore.cpp:39:8 [opt] frame rust-lang#13: 0x000000010cda7aaa libclang_rt.tsan_iossim_dynamic.dylib`__tsan::InitializeLibIgnore() at tsan_interceptors_posix.cpp:219:16 [opt] frame rust-lang#14: 0x000000010cdce0bb libclang_rt.tsan_iossim_dynamic.dylib`__tsan::Initialize(thr=0x0000000110141400) at tsan_rtl.cpp:403:3 [opt] frame rust-lang#15: 0x000000010cda7b8e libclang_rt.tsan_iossim_dynamic.dylib`__tsan::ScopedInterceptor::ScopedInterceptor(__tsan::ThreadState*, char const*, unsigned long) [inlined] __tsan::LazyInitialize(thr=0x0000000110141400) at tsan_rtl.h:665:5 [opt] frame rust-lang#16: 0x000000010cda7b86 libclang_rt.tsan_iossim_dynamic.dylib`__tsan::ScopedInterceptor::ScopedInterceptor(this=0x000000030c747af8, thr=0x0000000110141400, fname=<unavailable>, pc=4568918787) at tsan_interceptors_posix.cpp:247:3 [opt] frame rust-lang#17: 0x000000010cda7bb9 libclang_rt.tsan_iossim_dynamic.dylib`__tsan::ScopedInterceptor::ScopedInterceptor(this=0x000000030c747af8, thr=<unavailable>, fname=<unavailable>, pc=<unavailable>) at tsan_interceptors_posix.cpp:246:59 [opt] frame rust-lang#18: 0x000000010cdb72b7 libclang_rt.tsan_iossim_dynamic.dylib`::wrap_strlcpy(dst="\xd2", src="0xd1d398d1bb0a007b", size=20) at sanitizer_common_interceptors.inc:7386:3 [opt] frame rust-lang#19: 0x0000000110542b03 libsystem_c.dylib`__guard_setup + 140 frame rust-lang#20: 0x00000001104f8ab4 libsystem_c.dylib`_libc_initializer + 65 ... ``` rdar://83723445 Differential Revision: https://reviews.llvm.org/D111243

…D112621 It seems like `LHS` and `RHS` could be empty range sets. This caused an assertion failure inside RangeConstraintManager. I'm hoisting out the check from the function into the call-site.

…tePluginObject After llvm#68052 this function changed from returning a nullptr with `return {};` to returning Expected and hitting `llvm_unreachable` before it could do so. I gather that we're never supposed to call this function, but on Windows we actually do call this function because `interpreter->CreateScriptedProcessInterface()` returns `ScriptedProcessInterface` not `ScriptedProcessPythonInterface`. Likely because `target_sp->GetDebugger().GetScriptInterpreter()` also does not return a Python related class.

`----------------------------- # error: command failed with exit status: 0xc000001d ``` That might be a bug on the Windows side, or an artifact of how our build is setup, but whatever it is, having `CreatePluginObject` return an error and the caller check it, fixes the failing test. The built lldb can run the script command to use Python, but I'm not sure if that means anything.

TestCases/Misc/Linux/sigaction.cpp fails because dlsym() may call malloc on failure. And then the wrapped malloc appears to access thread local storage using global dynamic accesses, thus calling ___interceptor___tls_get_addr, before REAL(__tls_get_addr) has been set, so we get a crash inside ___interceptor___tls_get_addr. For example, this can happen when looking up __isoc23_scanf which might not exist in some libcs. Fix this by marking the thread local variable accessed inside the debug checks as "initial-exec", which does not require __tls_get_addr. This is probably a better alternative to llvm#83886. This fixes a different crash but is related to llvm#46204. Backtrace: ``` #0 0x0000000000000000 in ??
