WebJan 28, 2024 · Summary. D73474 disabled the generation of interworking thunks for branch relocations to non STT_FUNC symbols. This patch handles the case of BL and BLX instructions to non STT_FUNC symbols. LLD would normally look at the state of the caller and the callee and write a BL if the states are the same and a BLX if the states are different. Notes (Nhdr) ELF notes allow for appending arbitrary information for the system to use. They are largely used by core files (e_type of ET_CORE), but many projects define their own set of extensions. For example, the GNU tool chain uses ELF notes to pass information from the linker to the C library.
