Revision:	1.5
Committed:	2002-10-02T15:55:09Z (22 years, 1 month ago) by gbeauche
Content type:	text/plain
Branch:	MAIN
CVS Tags:	nigel-build-12
Changes since 1.4:	+1 -1 lines
Log Message:	- Remove dead code in readcpu.cpp concerning CONST_JUMP control flow. - Replace unused fl_compiled with fl_const_jump - Implement block inlining enabled with USE_INLINING && USE_CHECKSUM_INFO. However, this is currently disabled as it doesn't give much and exhibits even more a cache/code generation problem with FPU JIT compiled code. - Actual checksum values are now integral part of a blockinfo regardless of USE_CHECKSUM_INFO is set or not. Reduce number of elements in that structure and speeds up a little calculation of checksum of chained blocks. - Don't care about show_checksum() for now.
