Fusing Adjacent Loops With Unequal Trip Counts (
-Xsenable-unequal-tc-fusion
)

Use the
-Xsenable-unequal-tc-fusion
 flag in your
dpcpp
 command to direct the
Intel® oneAPI
DPC++/C++
 Compiler
 to fuse adjacent loops with different trip counts into a single loop without affecting either loop's functionality.
Example
dpcpp -fintelfpga -Xshardware -Xsenable-unequal-tc-fusion <source_file>.cpp
For more information about fusing loops, refer to Fuse Loops to Reduce Overhead and Improve Performance.
