Invalid opcode 0 during interactive JIT execution #26

Closed 0x7CFE closed 11 years ago

0x7CFE commented 11 years ago

This happens when we try to use Jit compiler in interactive (console) mode. When the same code is inserted into the image file and compiled using ImageBuilder all works as expected.

->Jit do: [ 1 ]
JIT: Invalid opcode 0 at offset 13 in method doItCommand
JIT: Invalid opcode 0 at offset 15 in method doItCommand
JIT: Invalid opcode 0 at offset 17 in method doItCommand
JIT: Invalid opcode 0 at offset 19 in method doItCommand
JIT: Invalid opcode 0 at offset 21 in method doItCommand

The soft part is affected too:

There should be no empty 16 and 18 bytecodes. The problem must be in Smalltalk part.
