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.
