[Bug fortran/30367] New: gfortran compile times excessive with -Wall

[Bil dot Kleb at NASA dot gov]

Hi,

Gfortran successfully compiles our FUN3D Fortran 90 code base (~600KLOC) and
does so in comparable time to other compilers.  When -Wall is turned on,
however, the compile times of certain large routines (e.g., the 12KLOC
Adjoint/residual_turbulent.f90), the compilation time increases from a few
minutes to an hour.

Unfortunately, the code is U.S. Person export controlled, but Steve Kargl
successfully obtained a copy in the past (and could request an updated,
autoconf'd version by sending a request to fun_support@larc.nasa.gov).

Sorry about the lame bug report, but I'll be glad to furnish whatever further
details I can given the export restriction.

Regards,
