why mysqld so big. Is any way to shrink it

[yx jiang]

File mysql in version 5.7.23 is more than 200M. But the text,data,bss segment are small like this

text data bss dec hex filename
23377448 1667344 781744 25826536 18a14e8 ./sql/mysqld

My cmake options like this

cmake ../ \
-DBUILD_CONFIG=mysql_release \
-DCMAKE_BUILD_TYPE=RelWithDebInfo \
-DWITH_BOOST=/home/jiangyx/tmp/mysql_compile_optimize/mysql-5.7.23/boost \

-DCMAKE_CXX_FLAGS="-O3" \
-DWITH_SYSTEMD=1 \
-DWITH_INNODB_MEMCACHED=0 \

-DWITH_EMBEDDED_SERVER=0 \
