Thanks for your feedback. I've added additional check to dyngen.c, which
checks that function has either save; in the beginning and ret; restore;
in the end, or ends in retl; nop;. That allowed me to get past the arm
target build failure. Now it fails (during dyngen check) on ppc target, the
culprit is the following function:
Just keep the instruction after retl, if it's not a nop. Stack adjustments
could be combined someplace, but that's a problem with all architectures, not
just sparc.
That is:
insn1
retl
insn3
should become:
insn1
insn2
In some cases there is just one instruction after retl with nothing before
it.
Sorry, I am not familiar with qemu internals enough to understand that. It
currently fails the build in the sanity check implemented in dyngen.c. We
figured out so far that there might be two valid cases: save;...ret;restore;
and ....;retl;nop;. Are you saying that the function ending in
retl;some_insn; is valid as well and the check has to be modified yet
again to accomodate this (third) case?
