Revision: 1.7
Committed: 2003-03-21T19:12:44Z (21 years, 8 months ago) by gbeauche
Content type: text/plain
Branch: MAIN
CVS Tags: nigel-build-12, nigel-build-13
Changes since 1.6: +6 -0 lines
Log Message:
Remove some dead code. Start implementation of optimized calls to interpretive
fallbacks for untranslatable instruction handlers. Disabled for now since
call_m_01() is not correctly imeplemented yet.
