-Subject: [PATCH] riscv: Make contribs build again.
-
-The issue was that the LINKAGE_TEMP_REG being NL3 was a C argument
-register, so of course that caused clashing on C call-out, causing
-problems with run-program. Going back to NL7 didn't work either
-because it wasn't getting saved before entry into the trampoline. The
-code here used to have NL7 before the trampoline code was gutted and
-then restored, so I'm wondering how this ever worked before, because
-it definitely did. Pick LIP as the TEMP_REG now because not only does
-it get saved, it's also the least likely thing to get disturbed by
-clobbering.
-
-Fixes #lp2002930.
-
-Also remove assembly routine printing because it doesn't need to be
-part of the build script (unlike the other files in output/ which
-can't trivially be recovered from a built image), and because not all
-disassembler printers have been written on riscv yet.
