x86 guest: look at FP accuracy
-Test
-~~~~
-Test adc/sbb carry dependency in memcheck
-
-
Optimisation opportunities
~~~~~~~~~~~~~~~~~~~~~~~~~~
Improved isel for memcheck artefacts on x86 (generate neg ; sbbl)
Assess tt_fast miss rates
-Better register allocation - spilling reduction
-
-iropt less conservative re precise exns
-
improve stack-update pass
proper profiling machinery
x86 iselIntExpr_RMI: actually generate the M case if possible
+
JIT speedups
~~~~~~~~~~~~
Ensure incremental flatness throughout
disallow dirty helpers from writing SP/IP
-make instrumentation work at no optimisation
-
write API doc, clarify IR semantics
make IR utils module
-tt/tc simplification, also profiling
-
generic stack pointer identification at startup?
New memstack_k: old or new sp?
-
-Set host FPU mode before starting. Also set Dflag = 0
-
-skin_panic -> tool_panic
