Bug ID: 97017
Summary: The function determine_precision is called twice for
each formatted real write
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libfortran
Assignee: unassigned at gcc dot gnu.org
Reporter: jvdelisle at charter dot net
Target Milestone: ---
I discovered this while working on the EX formattting feature. The
determine_precision function is called by both get_precision and inside the
macro FORMAT_FLOAT used by get_float_string.
To me this implies we have something factored wrong as we should not have to
call it twice to get things done. (a small performance issue as well as
obscure)
A simple test case will show the issue in a debugger:
! pr93727 EX Format Specifiers
program main
implicit none
real(4) :: r4
real(8) :: r8
r4 = 3.14158_4
r8 = 12.3456789_8
print *, r4, r8
end program main
