Fangrui Song b451f3588d [sanitizer] Place module_ctor/module_dtor in llvm.used ... This removes an abuse of ELF linker behaviors while keeping Mach-O/COFF linker behaviors unchanged. ELF: when module_ctor is in a comdat, this patch removes reliance on a linker abuse (an SHT_INIT_ARRAY in a section group retains the whole group) by using SHF_GNU_RETAIN. No linker behavior difference when module_ctor is not in a comdat. Mach-O: module_ctor gets `N_NO_DEAD_STRIP`. No linker behavior difference because module_ctor is already referenced by a `S_MOD_INIT_FUNC_POINTERS` section (GC root). PE/COFF: no-op. SanitizerCoverage already appends module_ctor to `llvm.used`. Other sanitizers: llvm.used for local linkage is not implemented in `TargetLoweringObjectFileCOFF::emitLinkerDirectives` (once implemented or switched to a non-local linkage, COFF can use module_ctor in comdat (i.e. generalize ELF-specific rL301586)). There is no object file size difference. Reviewed By: vitalybuka Differential Revision: https://reviews.llvm.org/D106246		2021-07-21 14:03:26 -07:00
