code coverage for dpc++

KimBioInfoStudio — Tue, 22 Jun 2021 03:02:32 GMT

when I try get code coverage of dpc++ code I find a error like, i search and find a similar erorr https://community.intel.com/t5/Intel-C-Compiler/undefined-reference-to-intel-fast-memcpy-when-using-intrinsics/td-p/969564, but seems libirc form icc, and idea on how to resolve this problem?

$echo "int main(){return 0;}" >> foo.cc
$clang++ -v -fprofile-arcs -ftest-coverage foo.cc -o foo

Please use the ICX driver instead of the clang++ driver.

For eg -

icx -fprofile-arcs -ftest-coverage codecov.cpp -o codecov

I am also facing issue to get the codecoverage for FlexRAN codebase.
For ICC , i am using the below FLAGS but its not working(Compliation error) with ICX.
LD_FLAGS += -prof-gen:srcpos
CC_FLAGS := -prof-gen:srcpos
