-- test macro system
+- Add new instructions such as: setcond, clz, ctz, popcnt.
-- test conditional jumps
+- See if it is worth exporting mul2, mulu2, div2, divu2.
-- test mul, div, ext8s, ext16s, bswap
-
-- generate a global TB prologue and epilogue to save/restore registers
- to/from the CPU state and to reserve a stack frame to optimize
- helper calls. Modify cpu-exec.c so that it does not use global
- register variables (except maybe for 'env').
-
-- fully convert the x86 target. The minimal amount of work includes:
- - add cc_src, cc_dst and cc_op as globals
- - disable its eflags optimization (the liveness analysis should
- suffice)
- - move complicated operations to helpers (in particular FPU, SSE, MMX).
-
-- optimize the x86 target:
- - move some or all the registers as globals
- - use the TB prologue and epilogue to have QEMU target registers in
- pre assigned host registers.
+- Support of globals saved in fixed registers between TBs.
Ideas:
- Move the slow part of the qemu_ld/st ops after the end of the TB.
-- Experiment: change instruction storage to simplify macro handling
- and to handle dynamic allocation and see if the translation speed is
- OK.
-
-- change exception syntax to get closer to QOP system (exception
+- Change exception syntax to get closer to QOP system (exception
parameters given with a specific instruction).
+
+- Add float and vector support.
