We have special code which handles the case where the PC lands outside the function bounds (but still within the correct module). However that fails when the PC actually ends up outside any module. Currently, this breaks TestNoreturnUnwind on android x86_64, but I am pretty sure it can be reproduced on any target. -- You are receiving this mail because: You are on the CC list for the bug. ___ llvm-bugs mailing list llvm-bugs@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-bugs

[llvm-bugs] [Bug 31197] New: [MS] Clang mangles lambdas in member initializers incorrectly
https://llvm.org/bugs/show_bug.cgi?id=31197
Bug ID: 31197
Summary: [MS] Clang mangles lambdas in member initializers
incorrectly
Product: clang
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: LLVM Codegen
Assignee: unassignedclangb...@nondot.org
Reporter: r...@google.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
Consider:
struct A {
int x = []() { return 1; }();
int y = []() { return 2; }();
};
int main() {
A a;
return a.x + a.y;
}
Clang optimizes this program to return 2 on Windows, because both lambdas use
the mangling context of the expression evaluation contexts of 'x' and 'y'
respectively.
This is underlying cause of the current Windows build failures in
ToolingTest.cpp:

https://llvm.org/bugs/show_bug.cgi?id=31200 Bug ID: 31200 Summary: clang-3.8.1 segfault on Mountain Lion during preprocessing in RemoveDuplicates Product: clang Version: 3.8 Hardware: PC OS: All Status: NEW Severity: normal Priority: P Component: -New Bugs Assignee: unassignedclangb...@nondot.org Reporter: jerem...@apple.com CC: llvm-bugs@lists.llvm.org Classification: Unclassified Created attachment 17682 --> https://llvm.org/bugs/attachment.cgi?id=17682&action=edit CMakeCCompilerId.c cmake based projects are failing to compile using clang 3.8.1 on Mountain Lion (newer versions aren't currently building on Mountain Lion, so I'm not sure if this is fixed). In comparison, clang 3.7.1 works fine. As this fails during preprocessing, I cannot provide preprocessed source. This issue does not occur with clang-3.8.1 on Sierra with the same input $ clang-mp-3.7 --version clang version 3.7.1 (tags/RELEASE_371/final) Target: x86_64-apple-darwin12.6.0 Thread model: posix $ clang-mp-3.8 --version clang version 3.8.1 (tags/RELEASE_381/final) Target: x86_64-apple-darwin12.6.0 Thread model: posix InstalledDir: /opt/local/libexec/llvm-3.8/bin $ clang-mp-3.7 -E CMakeCCompilerId.c -o /tmp/CMakeCCompilerId.pp.c $ clang-mp-3.8 -E CMakeCCompilerId.c -o /tmp/CMakeCCompilerId.pp.c 0 libLLVM.dylib 0x0001057bd2ec llvm::sys::PrintStackTrace(llvm::raw_ostream&) + 43 1 libLLVM.dylib 0x0001057bcba3 llvm::sys::RunSignalHandlers() + 44 2 libLLVM.dylib 0x0001057bd6c8 SignalHandler(int) + 153 3 libsystem_c.dylib 0x7fff87a0690a _sigtramp + 26 4 libsystem_c.dylib 0x0002 _sigtramp + 2019530514 5 libLLVM.dylib 0x000105785847 llvm::SmallPtrSetImplBase::insert_imp(void const*) + 133 6 clang 0x00010473384e llvm::SmallPtrSetImpl::insert(clang::DirectoryEntry const*) + 24 7 clang 0x00010473322e RemoveDuplicates(std::__1::vector >&, unsigned int, bool) + 309 8 clang 0x000104731c49 clang::ApplyHeaderSearchOptions(clang::HeaderSearch&, clang::HeaderSearchOptions const&, clang::LangOptions const&, llvm::Triple const&) + 4821 9 clang 0x0001046fa800 clang::CompilerInstance::createPreprocessor(clang::TranslationUnitKind) + 1456 10 clang 0x000104726d19 clang::FrontendAction::BeginSourceFile(clang::CompilerInstance&, clang::FrontendInputFile const&) + 2365 11 clang 0x0001046fd013 clang::CompilerInstance::ExecuteAction(clang::FrontendAction&) + 599 12 clang 0x00010474fba1 clang::ExecuteCompilerInvocation(clang::CompilerInstance*) + 3273 13 clang 0x0001044a0685 cc1_main(llvm::ArrayRef, char const*, void*) + 1243 14 clang 0x00010449f942 main + 8084 15 libdyld.dylib 0x7fff864127e1 start + 0 16 libdyld.dylib 0x002f start + 2042550350 Stack dump: 0.Program arguments: /opt/local/libexec/llvm-3.8/bin/clang -cc1 -triple x86_64-apple-macosx10.8.0 -Wdeprecated-objc-isa-usage -Werror=deprecated-objc-isa-usage -E -disable-free -disable-llvm-verifier -main-file-name CMakeCCompilerId.c -mrelocation-model pic -pic-level 2 -mthread-model posix -mdisable-fp-elim -masm-verbose -munwind-tables -target-cpu core2 -target-linker-version 264.3.102 -dwarf-column-info -debugger-tuning=lldb -resource-dir /opt/local/libexec/llvm-3.8/bin/../lib/clang/3.8.1 -fdebug-compilation-dir /Users/jeremy/src/macports/dports/www/webkit2-gtk-devel/work/build/CMakeFiles/3.7.0/CompilerIdC -ferror-limit 19 -fmessage-length 233 -stack-protector 1 -fblocks -fobjc-runtime=macosx-10.8.0 -fencode-extended-block-signature -fmax-type-align=16 -fdiagnostics-show-option -fcolor-diagnostics -o /tmp/CMakeCCompilerId.pp.c -x c CMakeCCompilerId.c clang: error: unable to execute command: Segmentation fault: 11 clang: error: clang frontend command failed due to signal (use -v to see invocation) clang version 3.8.1 (tags/RELEASE_381/final) Target: x86_64-apple-darwin12.6.0 Thread model: posix InstalledDir: /opt/local/libexec/llvm-3.8/bin clang: note: diagnostic msg: PLEASE submit a bug report to http://llvm.org/bugs/ and include the crash backtrace, preprocessed source, and associated run script. clang: error: unable to execute command: Segmentation fault: 11 clang: note: diagnostic msg: Error generating preprocessed source(s). -- You are receiving this mail because: You are on the CC list for the bug. ___ llvm-bugs mailing list llvm-bugs@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-bugs
