ARIES(5) ARIES(5)
(HP Integrity Systems Only)
If this option flag is enabled (
-corepid), the core file name will be core.PA-
RISC_application_name.PID
.
The default state of this option flag is disabled (
-nocorepid ).
-[no]fpsr_trans
[Disables] enables the dynamic translation of PA-RISC basic blocks that access and modify the
Floating Point Acess Regiser (FPSR : fr0L) frequently.
The default state of this option flag is disabled (
-nofpsr_trans ).
-[no]help
[Disables] enables the printing of ARIES options and their minimum, maximum, and default
values on stderr. If this option flag is enabled (
-help) ARIES will exit after printing the
available options.
The default state of this option flag is disabled (
-nohelp).
-[no]mem_fence
[Disables] enables the generation of memory fence
mf instruction in translation for ordered
memory operations of PA-RISC application.
WARNING: Enabling (
-mem_fence ) this option flag will slow down the performance of
memory loads in ARIES translated code. Enable (-mem_fence) this option flag only if the
PA-RISC application expecting strong memory ordering (program uses volatile variables)
fails under ARIES.
NOTE: Enabling the ARIES option flag -mem_order does not automatically enable
(-mem_order) this option flag.
The default state of this option flag is disabled (-nomem_fence ).
-[no]mem_min
[Disables] enables the minimum memory footprint (process resident memory size) under ARIES.
Enabling (-mem_min) this option flag is useful for applications that have constraints on process
memory footprint. If this option flag is enabled (-mem_min), the sizes of all ARIES memory
segments are set to their minimum values.
WARNING: Enabling (-mem_min) this option flag may cause performance slowdown due to
increased number of ARIES translation code buffer flushes.
The default state of this option flag is disabled (-nomem_min).
-[no]mem_order
[Disables] enables the strong memory ordering in ARIES. You should enable (-mem_order)
this option flag only when your PA-RISC application expecting strong memory ordering fails
under ARIES. Such an application would be the one, which does not use memory ordering
semantics like
,O completer in load/store instructions or volatile cast in high level
code, and still expects strong memory ordering.
WARNING: Enabling (-mem_order) this option flag may cause 2x-3x performance slowdown.
The default state of this option flag is disabled (-nomem_order ).
-[no]opt_fpgr
[Disables] enables the mapping of the emulated FP (Floating Point) register context on general
register stack. The performance of the floating point intensive PA-RISC applications may be
better if this option flag is enabled (-opt_fpgr).
The default state of this option flag is enabled (-opt_fpgr).
-[no]opt_reorder
[Disables] enables the ARIES optimizations for dynamically translated code to re-order PA-RISC
state changing instructions, loads, and updates to general registers in order to achieve better
scheduling of translated code.
WARNING: Do not enable (-opt_reorder ) this option flag with multi-threaded applications
like JVM which expect precise delivery of synchronous exceptions and register updates. Such
applications may crash with core file if this option flag is enabled (-opt_reorder ).
The default state of this option flag is disabled (-noopt_reorder).
