Comment 5 Alexandra Petlanová Hájková 2019-07-30 12:06:48 UTC
I verified g++ does not link against libgcc.a for gcc-8.3.1-4.1:
g++ -O2 -fpic -shared reproducer.c
eu-readelf -s a.out | grep cpu_model
3: 0000000000000000      0 NOTYPE  GLOBAL DEFAULT    UNDEF __cpu_model
50: 0000000000000000      0 NOTYPE  GLOBAL DEFAULT    UNDEF __cpu_model

and g++ links against libgcc.a for gcc-8.3.1-4.2.el8:
++ -O2 -fpic -shared reproducer.c
eu-readelf -s a.out | grep cpu_model
50: 0000000000202030     16 OBJECT  LOCAL  DEFAULT       22 __cpu_model
