            Bug ID: 92210
           Summary: no warning for invariable used in loop condition
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: tangyixuan at mail dot dlut.edu.cn
  Target Milestone: ---

There is no warning for an invariable used in loop condition:

$: cat s.c
int main(){
  for(int i = 0; i <2;){
  }
}

$: gcc-trunk -Wall -Wextra -pedantic -c s.c

gcc version 10.0.0 20191020 (experimental) (GCC)
target: Ubuntu 4.8.5-4ubuntu8~14.04.2

$: clang-trunk -Weverything -pedantic -c s.c
s.c:2:18: warning: variable 'i' used in loop condition not modified in loop
body [-Wfor-loop-analysis]
  for(int i = 0; i <2;){
                 ^
1 warning generated.

Is it a better way to report the warning in loop condition, just like the way
Clang does?
