f3fba20c9c Create type maps during trace entry and in each side exit and store them in the LIR using LIR_skip. Use these type maps during trace entry and exit. 2008-07-01 19:43:10 -07:00

d3e7a57a68 Fix deallocation bug in the recorder. We will have to lift more code Tamarin's Interpreter to stabilize the recording. 2008-07-01 02:37:07 -07:00

84274f1b33 Save the VM registers into markRegs at opcode entry and restore that state when ending or aborting recording. The same info is pushed into sideexit and used by guards. With this change we can eliminate the hack in MONITOR_BRANCH that had to adjust the stack pointer depending on the opcode type, and it also allows us to trace through the recently added boolean guard opcode fusing. This improves trace code quality, since only the pre-conditional check state is saved. The guard restores into that state, so the trace code doesn't have to emit the value of the conditional evaluation onto the stack, saving a handful ops. 2008-06-30 18:31:29 -07:00

d8d25140f9 Mockup of trace execution. Speedup is 10x for a tight loop. Keep in mind that this is a hack and the trace code is not optimized yet. 2008-06-29 23:02:22 -07:00

e461a72736 The table is now per-thread in a multi-threaded environment, and per-runtime otherwise. During code generation we merely allocate a loop table slot to each loop. Each thread will enlarge the table as needed in JSOP_HEADER. 2008-05-30 18:58:43 -07:00
