                    -fno-omit-frame-pointer on GCC 10.2.0
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED

  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=53741&action=edit
C source code

gcc version 10.2.0 (SiFive GCC-Metal 10.2.0-2020.12.8)

1.compile test.c code
riscv64-unknown-elf-gcc -static -O0 -g -fno-omit-frame-pointer test.c -o test
-lm

2.Using perf record
sudo perf record -e cpu-clock -g ./test

3.Using perf script
sudo perf script > test.perf




at test.perf, you will find that normal_loop call normal_loop

test   769 22186.901402:     250000 cpu-clock: 
                   1018a normal_loop+0x34 (/home/test)
                   1019c normal_loop+0x46 (/home/test)
