Lu, Hongjiu's advice:
"
All shared libraries should be CET enabled. GCC provides <cet.h> which can be included
in assembly codes to generate CET maker when compiling with -fcf-protection.
"
Hongjiu need a pull request to ICU, and which need a ICU JIRA to match the pull request.
So we create this ICU JIRA.
Thanks!
