Lu Date: Sat Jun 19 05:12:48 2021 -0700 x86: Add -m[no-]direct-extern-access Add -m[no-]direct-extern-access and nodirect_extern_access attribute. -mdirect-extern-access is the default. With nodirect_extern_access attribute, GOT is always used to access undefined data and function symbols with nodirect_extern_access attribute, including in PIE and non-PIE. With -mno-direct-extern-access: 1. Always use GOT to access undefined data and function symbols, including in PIE and non-PIE. These will avoid copy relocations in executables. This is compatible with existing executables and shared libraries. 2. In executable and shared library, bind symbols with the STV_PROTECTED visibility locally: a. The address of data symbol is the address of data body. b. For systems without function descriptor, the function pointer is the address of function body. c. The resulting shared libraries may not be incompatible with executables which have copy relocations on protected symbols or use executable PLT entries as function addresses for protected functions in shared libraries. 3. Update asm_preferred_eh_data_format to select PC relative EH encoding format with -mno-direct-extern-access to avoid copy relocation. 4. Add ix86_reloc_rw_mask for TARGET_ASM_RELOC_RW_MASK to avoid copy relocation with -mno-direct-extern-access. gcc/ PR target/35513 PR target/100593 * config/i386/gnu-property.cc: Include "i386-protos.h".
