New ContributorFPGA report fails for matrix transpose
Hi everyone,
the FPGA report fails for a simple kernel for the matrix transpose operation. The output asks me to
PLEASE submit a bug report to https://software.intel.com/en-us/support/priority-support and include the crash backtrace.
But the web page does not work well for me. Thus, I attach the error messages and source code here.
- The source code: attached.
- The optimization report:
icpx -fsycl -fintelfpga -DFPGA_HARDWARE -std=c++2b -Wall -Wextra -Wpedantic -Werror -O3 mattrans.cpp -Xshardware -fsycl-link=early -Xsv -Xsparallel=16 -Xsffp-reassociate -Xsffp-contract=fast -o mattrans.a
- The error messages:
