* std.cache_hash exposes Hasher type * std.cache_hash makes hasher_init a global const * std.cache_hash supports cloning so that clones can share the same open manifest dir handle as well as fork from shared hasher state * start to populate the cache_hash for stage2 builds * remove a footgun from std.cache_hash add function * get rid of std.Target.ObjectFormat.unknown * rework stage2 logic for resolving output artifact names by adding object_format as an optional parameter to std.zig.binNameAlloc * support -Denable-llvm in stage2 tests * Module supports the use case when there are no .zig files * introduce c_object_table and failed_c_objects to Module * propagate many new kinds of data from CLI into Module and into linker.Options * introduce -fLLVM, -fLLD, -fClang and their -fno- counterparts. closes #6251. - add logic for choosing when to use LLD or zig's self-hosted linker * stub code for implementing invoking Clang to build C objects * add -femit-h, -femit-h=foo, and -fno-emit-h CLI options
