Fangrui Song b3fd3a9ac3 [IR] Allow absence for Min module flags and make AArch64 BTI/PAC-RET flags backward compatible ... D123493 introduced llvm::Module::Min to encode module flags metadata for AArch64 BTI/PAC-RET. llvm::Module::Min does not take effect when the flag is absent in one module. This behavior is misleading and does not address backward compatibility problems (when a bitcode with "branch-target-enforcement"==1 and another without the flag are merged, the merge result is 1 instead of 0). To address the problems, require Min flags to be non-negative and treat absence as having a value of zero. For an old bitcode without "branch-target-enforcement"/"sign-return-address", its value is as if 0. Differential Revision: https://reviews.llvm.org/D129911		2022-07-18 09:35:12 -07:00
