Prerequisite:
lcov
. Install via sudo apt-get install lcov
Either of gcov <= 7
, or llvm-cov >= 11
gcov <= 7
. Install gcc sudo apt-get install gcc
. For more information around managing multiple gcc/toolchains, please refer to this article.llvm-cov >= 11
. You can either install using apt/yum/dnf, or the official LLVM installation script:wget https://apt.llvm.org/llvm.sh chmod +x llvm.sh sudo ./llvm.sh 11
If your platform cannot install either of them, you can use another platform to analyze the generated gcno
and gcda
files. Ubuntu 18.04 has gcc-7 by default, and can install llvm 11 using the above script.
$ make COV=1 $ cd bin && ./app && cd .. $ make gen_cov_html
Then open html/index.html
, where amazing happens!
sgx_cov supports xargo as well:
$ XARGO_SGX=1 make COV=1 $ cd bin && ./app && cd .. $ XARGO_SGX=1 make gen_cov_html
global_exit
for sgx_urts
on exit
function using global_dtors_object!
macro, and invoke sgx_cov::cov_writeout()
.gcno
would be generated during compile time at Target_Dir
.gcna
would be generated during run time at Target_dir
make gen_cov_html
would process .gcno
and .gcna
and generate html results.To be continued ...
