Whether to use quad-word load and store instructions (lq
and stq
) in the kernel and in jitted code. POWER only.
Whether to preload JIT failure continuation.
Whether to use JIT compilation.
Whether to use JIT compilation of FLI predicates. Ignored if JIT compilation is not enabled.
This feature has not yet been implemented on POWER.
Whether to pass the Caller information in the link register. If it is disabled then the information is passed in a register, or not at all. POWER only.
The path to a OPDIS installation, e.g. /usr/local/opdis. This is needed in order to get machine code disassembly while dumping IR-code. Ignored unless --enable-opdis is also passed.
Whether OPDIS should be used for disassembling machine code in debug output.
OPDIS is supported on Linus, OS X and POWER. OPDIS itself needs to be modified to build on POWER.
On OS X the path to binutils must be specified with --with-binutils=PATH on order to use OPDIS.
Note: OPDIS must never be included in a released build. Licencing issues.
Whether perf
should be supported, i.e. so that jitted
code can be disassembled and annotated by perf
.
Supported on 64-bit Intel Linux and on (64-bit) POWER Linux.
Whether oprofile
should be supported. Nowadays perf
is preferred.
