## Description This PR fixes a segmentation fault that occurs when passing options requiring arguments via `-Xopenmp-target=<triple>`. The issue was that the function `Driver::getOffloadArchs` did not properly parse the extracted option, but instead assumed it was valid, leading to a crash when incomplete arguments were provided. ## Backtrace ```sh llvm-project/build/bin/clang++ main.cpp -fopenmp=libomp -fopenmp-targets=powerpc64le-ibm-linux-gnu -Xopenmp-target=powerpc64le-ibm-linux-gnu -o PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.

…reporting (#131756)
### Description
This PR resolves a deadlock between AddressSanitizer (ASan) and
LeakSanitizer (LSan)
that occurs when both sanitizers attempt to acquire locks in conflicting
orders across
threads. The fix ensures safe lock acquisition ordering by preloading
module information
before error reporting.
---
### Issue Details
**Reproducer**
```cpp
// Thread 1: ASan error path
int arr[1] = {0};
std::thread t([&]() {
arr[1] = 1; // Triggers ASan OOB error
});
// Thread 2: LSan check path
__lsan_do_leak_check();
```
**Lock Order Conflict**:
- Thread 1 (ASan error reporting):
1. Acquires ASan thread registry lock (B)
1. Attempts to acquire libdl lock (A) via `dl_iterate_phdr`
- Thread 2 (LSan leak check):
1. Acquires libdl lock (A) via `dl_iterate_phdr`
1. Attempts to acquire ASan thread registry lock (B)
This creates a circular wait condition (A -> B -> A) meeting all four
Coffman deadlock criteria.
---
### Fix Strategy
The root cause lies in ASan's error reporting path needing
`dl_iterate_phdr` (requiring lock A)
while already holding its thread registry lock (B). The solution:
1. **Preload Modules Early**: Force module list initialization _before_
acquiring ASan's thread lock
2. **Avoid Nested Locking**: Ensure symbolization (via dl_iterate_phdr)
completes before error reporting locks
Key code change:
```cpp
// Before acquiring ASan's thread registry lock:
Symbolizer::GetOrInit()->GetRefreshedListOfModules();
```
This guarantees module information is cached before lock acquisition,
eliminating
the need for `dl_iterate_phdr` calls during error reporting.
---
### Testing
Added **asan_lsan_deadlock.cpp** test case:
- Reproduces deadlock reliably without fix **under idle system
conditions**
- Uses watchdog thread to detect hangs
- Verifies ASan error reports correctly without deadlock
**Note**: Due to the inherent non-determinism of thread scheduling and
lock acquisition timing,
this test may not reliably reproduce the deadlock on busy systems (e.g.,
during parallel
`ninja check-asan` runs).
---
### Impact
- Fixes rare but severe deadlocks in mixed ASan+LSan environments
- Maintains thread safety guarantees for both sanitizers
- No user-visible behavior changes except deadlock elimination
---
### Relevant Buggy Code
- Code in ASan's asan_report.cpp
```cpp
explicit ScopedInErrorReport(bool fatal = false)
: halt_on_error_(fatal || flags()->halt_on_error) {
// Acquire lock B
asanThreadRegistry().Lock();
}
~ScopedInErrorReport() {
...

…lection (#136795) Fix a [test failure](llvm/llvm-project#136236 (comment)) in #136236, apply a minor renaming of statistics, and remerge. See details below. # Changes in #136236 Currently, `DebuggerStats::ReportStatistics()` calls `Module::GetSymtab(/*can_create=*/false)`, but then the latter calls `SymbolFile::GetSymtab()`. This will load symbols if haven't yet. See stacktrace below. The problem is that `DebuggerStats::ReportStatistics` should be read-only. This is especially important because it reports stats for symtab parsing/indexing time, which could be affected by the reporting itself if it's not read-only. This patch fixes this problem by adding an optional parameter `SymbolFile::GetSymtab(bool can_create = true)` and receiving the `false` value passed down from `Module::GetSymtab(/*can_create=*/false)` when the call is initiated from `DebuggerStats::ReportStatistics()`. --- Notes about the following stacktrace: 1. This can be reproduced. Create a helloworld program on **macOS** with dSYM, add `settings set target.preload-symbols false` to `~/.lldbinit`, do `lldb a.out`, then `statistics dump`. 2. `ObjectFile::GetSymtab` has `llvm::call_once`. So the fact that it called into `ObjectFileMachO::ParseSymtab` means that the symbol table is actually being parsed. ``` (lldb) bt * thread #1, queue = 'com.apple.main-thread', stop reason = step over frame #0: 0x0000000124c4d5a0 LLDB`ObjectFileMachO::ParseSymtab(this=0x0000000111504e40, symtab=0x0000600000a05e00) at ObjectFileMachO.cpp:2259:44 * frame #1: 0x0000000124fc50a0 LLDB`lldb_private::ObjectFile::GetSymtab()::$_0::operator()(this=0x000000016d35c858) const at ObjectFile.cpp:761:9 frame #5: 0x0000000124fc4e68 LLDB`void std::__1::__call_once_proxy[abi:v160006]<std::__1::tuple<lldb_private::ObjectFile::GetSymtab()::$_0&&>>(__vp=0x000000016d35c7f0) at mutex:652:5 frame #6: 0x0000000198afb99c libc++.1.dylib`std::__1::__call_once(unsigned long volatile&, void*, void (*)(void*)) + 196 frame #7: 0x0000000124fc4dd0 LLDB`void std::__1::call_once[abi:v160006]<lldb_private::ObjectFile::GetSymtab()::$_0>(__flag=0x0000600003920080, __func=0x000000016d35c858) at mutex:670:9 frame #8: 0x0000000124fc3cb0 LLDB`void llvm::call_once<lldb_private::ObjectFile::GetSymtab()::$_0>(flag=0x0000600003920080, F=0x000000016d35c858) at Threading.h:88:5 frame #9: 0x0000000124fc2bc4 LLDB`lldb_private::ObjectFile::GetSymtab(this=0x0000000111504e40) at ObjectFile.cpp:755:5 frame #10: 0x0000000124fe0a28 LLDB`lldb_private::SymbolFileCommon::GetSymtab(this=0x0000000104865200) at SymbolFile.cpp:158:39 frame #11: 0x0000000124d8fedc LLDB`lldb_private::Module::GetSymtab(this=0x00000001113041a8, can_create=false) at Module.cpp:1027:21 frame #12: 0x0000000125125bdc LLDB`lldb_private::DebuggerStats::ReportStatistics(debugger=0x000000014284d400, target=0x0000000115808200, options=0x000000014195d6d1) at Statistics.cpp:329:30 frame #13: 0x0000000125672978 LLDB`CommandObjectStatsDump::DoExecute(this=0x000000014195d540, command=0x000000016d35d820, result=0x000000016d35e150) at CommandObjectStats.cpp:144:18 frame #14: 0x0000000124f29b40 LLDB`lldb_private::CommandObjectParsed::Execute(this=0x000000014195d540, args_string="", result=0x000000016d35e150) at CommandObject.cpp:832:9 frame #15: 0x0000000124efbd70 LLDB`lldb_private::CommandInterpreter::HandleCommand(this=0x0000000141b22f30, command_line="statistics dump", lazy_add_to_history=eLazyBoolCalculate, result=0x000000016d35e150, force_repeat_command=false) at CommandInterpreter.cpp:2134:14 frame #16: 0x0000000124f007f4 LLDB`lldb_private::CommandInterpreter::IOHandlerInputComplete(this=0x0000000141b22f30, io_handler=0x00000001419b2aa8, line="statistics dump") at CommandInterpreter.cpp:3251:3 frame #17: 0x0000000124d7b5ec LLDB`lldb_private::IOHandlerEditline::Run(this=0x00000001419b2aa8) at IOHandler.cpp:588:22 frame #18: 0x0000000124d1e8fc LLDB`lldb_private::Debugger::RunIOHandlers(this=0x000000014284d400) at Debugger.cpp:1225:16 frame #19: 0x0000000124f01f74 LLDB`lldb_private::CommandInterpreter::RunCommandInterpreter(this=0x0000000141b22f30, options=0x000000016d35e63c) at CommandInterpreter.cpp:3543:16 frame #20: 0x0000000122840294 LLDB`lldb::SBDebugger::RunCommandInterpreter(this=0x000000016d35ebd8, auto_handle_events=true, spawn_thread=false) at SBDebugger.cpp:1212:42 frame #21: 0x0000000102aa6d28 lldb`Driver::MainLoop(this=0x000000016d35ebb8) at Driver.cpp:621:18 frame #22: 0x0000000102aa75b0 lldb`main(argc=1, argv=0x000000016d35f548) at Driver.cpp:829:26 frame #23: 0x0000000198858274 dyld`start + 2840 ``` # Changes in this PR top of the above Fix a [test failure](llvm/llvm-project#136236 (comment)) in `TestStats.py`. The original version of the added test checks that all modules have symbol count zero when `target.preload-symbols == false`. The test failed on macOS. Due to various reasons, on macOS, symbols can be loaded for dylibs even with that setting, but not for the main module. For now, the fix of the test is to limit the assertion to only the main module. The test now passes on macOS. In the future, when we have a way to control a specific list of plug-ins to be loaded, there may be a configuration that this test can use to assert that all modules have symbol count zero. Apply a minor renaming of statistics, per the [suggestion](llvm/llvm-project#136226 (comment)) in #136226 after merge.

When running the `openmp` testsuite on Solaris/amd64, many tests `FAIL` like ``` # | OMP: Error #11: Stack overflow detected for OpenMP thread #1 ``` In a `Debug` build, I also get ``` # | Assertion failure at kmp_runtime.cpp(203): __kmp_gtid_get_specific() < 0 || __kmp_gtid_get_specific() == i. ``` Further investigation shows that just setting `__kmp_gtid_mode` to 3 massively reduces the number of failures. Tested on `amd64-pc-solaris2.11` and `x86_64-pc-linux-gnu`.

The mcmodel=tiny memory model is only valid on ARM targets. While trying
this on X86 compiler throws an internal error along with stack dump.
#125641
This patch resolves the issue.
Reduced test case:
```
#include <stdio.h>
int main( void )
{
printf( "Hello, World!\n" );
return 0;
}
```
```
