Bug ID: 81344
Summary: Can't disable -ffpe-trap (or not documented)
Product: gcc
Version: 5.4.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: jellby at yahoo dot com
Target Milestone: ---
Once I enable a floating point exception trap with "-ffpe-trap=whatever", it
doesn't seem to be possible to disable it in the same command line (as it is
possible with warnings, for instance. An empty list as in "-ffpe-trap=" is
accepted, but it doesn't disable traps.
This would be useful when using a tool like CMake, where it is convenient to
set a default set of flags, and then override them if desired in specific
files, rather.
