- test macro system |
|---|---|
| 2 |
|
| 3 |
- test conditional jumps |
| 4 |
|
| 5 |
- test mul, div, ext8s, ext16s, bswap |
| 6 |
|
| 7 |
- generate a global TB prologue and epilogue to save/restore registers |
| 8 |
to/from the CPU state and to reserve a stack frame to optimize |
| 9 |
helper calls. Modify cpu-exec.c so that it does not use global |
| 10 |
register variables (except maybe for 'env'). |
| 11 |
|
| 12 |
- fully convert the x86 target. The minimal amount of work includes: |
| 13 |
- add cc_src, cc_dst and cc_op as globals |
| 14 |
- disable its eflags optimization (the liveness analysis should |
| 15 |
suffice) |
| 16 |
- move complicated operations to helpers (in particular FPU, SSE, MMX). |
| 17 |
|
| 18 |
- optimize the x86 target: |
| 19 |
- move some or all the registers as globals |
| 20 |
- use the TB prologue and epilogue to have QEMU target registers in |
| 21 |
pre assigned host registers. |
| 22 |
|
| 23 |
Ideas: |
| 24 |
|
| 25 |
- Move the slow part of the qemu_ld/st ops after the end of the TB. |
| 26 |
|
| 27 |
- Experiment: change instruction storage to simplify macro handling |
| 28 |
and to handle dynamic allocation and see if the translation speed is |
| 29 |
OK. |
| 30 |
|
| 31 |
- change exception syntax to get closer to QOP system (exception |
| 32 |
parameters given with a specific instruction). |
