Bug ID: 109216
Summary: Wrong behaviour explained in -fno-underscoring
documentation
Product: gcc
Version: 12.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: rhidalgochar at bloomberg dot net
Target Milestone: ---
In the documentation section for codegen options it has two parts explaining
the behaviour of -fno-underscoring (and implictly -funderscoring) and
-fsecond-underscore:
https://gcc.gnu.org/onlinedocs/gfortran/Code-Gen-Options.html
However under -fno-underscoring it has an example for -funderscoring that seems
to describe the -fsecond-underscore behaviour.
Indeed if I compile the following example into an object and look at the
symbols I see that j_ and max_count_ are found as undefined symbols, not j_ and
max_count__ as suggested, though I do get that if I compile it with
-fsecond-underscore.
code:
program main
integer i, j, max_count
i = j() + max_count(i, j())
end program main
