Description

The PR forcefully demotes the linkage of all global values to private after linking the modules, such that GOT entries will not be generated. 2 symbols are exempt from the demotion:

  • typeinfo: The kernel will need to read it;
  • now: To preserve RISC-V now-pinning feature.

2584776b6e nac3artiq: demote global value to private 
... except typeinfo & now symbols.
typeinfo will be read by the runtime linker; now is for now-pinning.
