Subject: Huge inefficiency on powerpc due to duplicated GOT
The same issue that led to having to reprocess non-GOT/PLT-type
relocations in ldso/libc seems to be making more trouble for us.
ld-musl-powerpc.so.1 contains nearly 2 whole pages of GOT, due to each
translation unit getting its own GOT in the .got2 section (and using
non-GOT reloc types) and having them all concatenated with no merging.
Anyone know what's up with this? Is it a toolchain bug, perhaps
resulting from secure-plt mode not being widely tested? Is there any
workaround?
