[PR40542] Sent patch for -n and -N support in LLD for upstream review [LTO] Investigated problems when using -Os -Oz with LTO, raised 2 PRs - error if clang linker invocation uses -Os and -Oz - strange error message when .bc used as a file extension for a separate compile and link step Crash in GNU ld when linking LLVM lto via the gold plugin. Looks like a memory access/corruption problem in the conversion from .bc to bfd.

Other miscellaneous reviews for some linker script support in LLD.

Investigation into why ld.bfd with NOLOAD on the .gnu.build-id section corrupts debug information.
