Inputs	[lldb][ObjectFileELF] Set ModuleSpec file offset and size In Android API level 23 and above, dynamic loader is able to load .so file directly from APK. https://android.googlesource.com/platform/bionic/+/master/ android-changes-for-ndk-developers.md# opening-shared-libraries-directly-from-an-apk ObjectFileELF::GetModuleSpecifications will load a .so file, which is page aligned and uncompressed, directly from a zip file. However it does not set the .so file offset and size to the ModuleSpec. Also crc32 calculation uses more data than the .so file size. Set the .so file offset and size to the ModuleSpec, and set the size to MapFileData length argument. For normal file, file_offset should be zero, and length should be the size of the file.

TestObjectFileELF.cpp	[LLDB] Omit loading local symbols in LLDB symbol table (#154809) https://discourse.llvm.org/t/rfc-should-we-omit-local-symbols-in-eekciihgtfvflvnbieicunjlrtnufhuelf-files-from-the-lldb-symbol-table/87384 Improving symbolication by excluding local symbols that are typically not useful for debugging or symbol lookups. This aligns with the discussion that local symbols, especially those with STB_LOCAL binding and STT_NOTYPE type (including .L-prefixed symbols), often interfere with symbol resolution and can be safely omitted. --------- Co-authored-by: Bar Soloveychik <barsolo@fb.com>	11 个月前
