Hello,
I have rebuilt the Redhat kaffe-1.0.6 src.rpm package for
linux-m68k, a few fixes were required, patch appended.
Fixes:
- config/m68k/jit.h: fix trampoline macro
- config/m68k/jit-m68k.def: -\
- config/m68k/jit3-m68k.def:--+- fix generation of cmpal insn pattern
generated invalid instruction previously (coredump)
- kaffe-1.0.6/kaffe/scripts/kaffe.in: fix ddd support, apparently
output of ddd --version changed somewhat
tried the regression tests - still not perfect but at least it doesn't
segfault immediately. Are some of the failures expected?
# make check-TESTS
