--- Comment #7 from Michael Osipov <michael.osipov at siemens dot com> ---
I'd like to request to seriously reconsider this ticket. We are currently
porting several 100 000 of LoC (electrical engineering) from HP Fortran F90 on
HP-UX to GFortran 9-11. The HP Fortran compiler convienently provides (for the
last 15 years):
> +FPOZVD and +FPo
Uppercase means enable and lowercase disable. I have the exact same situation
as Ignacio. CMake default config is +FPOZVD which translates to
-ffpe-trap=overflow,zero,invalid,denormal.
A small amount of applications disable a few flags to be runnable at all.
Properly applied with CMake
* Compile time: ./CMakeFiles/di1308.dir/flags.make:Fortran_FLAGS = +DSnative
+save -minshared +check=all +noppu +FPOZVD -w +FPo -g
* Link time: ./CMakeFiles/di1308.dir/link.txt:/opt/fortran90/bin/f90
-Wl,+s,+nodefaultrpath -Wl,-a,shared_archive -Wl,+n -Wl,+noobjdebug
-Wl,+dbgfile,di1308.dbg +DSnative +save -minshared +check=all +noppu +FPOZVD -w
+FPo -g <objects>
There must be a way to have the same in GCC.
