Revision: 1.3
Committed: 2002-10-02T15:55:10Z (21 years, 11 months ago) by gbeauche
Content type: text/plain
Branch: MAIN
Changes since 1.2: +5 -10 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.
