David Nadlinger efbae51f9d runtime: Validate ksupport ELF against hard-coded address ranges 
This would have caught the reduction in header padding with LLD 14.
In theory, we could just get rid of the hard-coded kernel CPU address
ranges altogether and use ksupport.elf as the one source of truth; the
code already exists in dyld. The actual base address of the file would
still need to be forwarded to the kernel-side libunwind glue, though,
as there doesn't seem to be a clean way to get the equivalent of
KSUPPORT_HEADER_SIZE through the linker script. I have left this as-is
with the hard-coded KERNELCPU_… constants for now.

occheung f79f7db3a2 dyld: handle rebind on symbols relocated by CALL_PLT 2022-06-01 12:44:33 +08:00
occheung 872f8f039f dyld: support additional RV32 reloc types 
The support of LO12 type requires the runtime linker to find the corresponding HI20 symbol. resolve_rela needs the entire relocation section for that.

occheung 50495097e5 dyld: rename pltrel to jmprel 
nac3ld will not generate PLT & its relocation section. There might not be a pltrel in that case.
On the other hand, rebinding will not be limited to the symbols in the PLT when linked with nac3ld.
Thus the renaming.
