19:03
Continuing work toward converting the VM to a register machine. (CVS 4708) (check-in: 426f31ec user: drh tags: trunk)
12:48
Continuing work toward converting the VM into a register machine. (CVS 4707) (check-in: a6dddebc user: drh tags: trunk)
2008-01-11
15:27
Do explicit range tests before attempting to convert a 64-bit float into a 64-bit integer. Some systems (windows) seem to throw exceptions if the conversion is out of range. Ticket #2880. (CVS 4706) (check-in: 4744257d user: drh tags: trunk)
00:06
Attempt to work around a bug in the Borland BCC 5.5.1 compiler. Ticket #2880. (CVS 4705) (check-in: 6de0ee49 user: drh tags: trunk)

Fix a test script problem associated with the new crash4.test file. Ticket #2882. (CVS 4701) (check-in: 1134c5ea user: drh tags: trunk)
23:04
All essential opcodes can now operate out of registers and completely avoid the stack. Many still optionally use the stack to support legacy code generation, but the stack is not required.
