error stop quiet=true generates calls

[foxtran]

Considering the following code:

subroutine test_quiet(stat)
  implicit none
  integer :: stat
  if (stat > 0) error stop 1, quiet=.true.
  if (stat == 42) print *, 'unreachable'
end subroutine test_quiet

that is compiled as follows:

ifx test.f90 -O3 -S

 the resulting code has `callq for_error_stop_quiet@PLT` that can be avoided since 

If QUIET= appears and the scalar-logical-expr has the value true, no output of signaling exceptions or stop code shall be produced

from Fortran 2023 Standard (11.4 STOP and ERROR STOP statements)

Hmm... There is no unreachable call after quiet stop (at IR level), while it should be.

[foxtran]

Sorry, I misread standard. Looks like it states that execution is still terminating, but in silent way (no output to IO).

That's correct. ERROR STOP always terminates execution - the difference between it and STOP (which also has QUIET=) is that ERROR STOP terminates all images in a coarray application.
