- xlopt
-
Enable kernel optimizations based on the specified value:
-
0: No kernel optimizations.
-
1: Computation of heap size, generation of guidance based on LLVM IR analysis, and insertion of loop pragmas.
-
2: The same optimizations as 1 with the addition of loop peeling for unrolled loops, and automatic inlining.
xlopt=2 -
- Xxloptstr
-
Option string to enable or disable optimizations in XLOpt level 1,2.
- -xlinline-threshold=T : set inlining threshold to T (default T = 5000, only for optlevel=2).
- -annotate-pragma : insertion of loop unrolling, pipelining, and flattening pragmas (default = true)
