My immediate reaction is "isn't Sparc an abandoned architecture?" See https://en.wikipedia.org/wiki/SPARC and https://lists.freebsd.org/pipermail/freebsd-sparc64/2020-January/010192.html

Though, no objection. You may still need some basic tests, similar to `test/ELF/ppc32-*` I tried hard to keep the number of tests small yet complete. Does sparc64 use TLS variant 2?


I've implemented a bunch of relocations found in my binaries with medium/large code model and IE TLS, the binaries link and run fine in Qemu.
The `elf64_sparc` emulation mode is now recognized, that's the name binutils use and I'm not aware of any other spelling/variation.
