.il files

Hello all,

I got the intel fortran 90 compilier up and working on my debian
system, but have one small snag. The optimization -fast (which
expands to -O3 -ipo -static) seems to produce a lot
of .il files in addition to .mod and .o files. I understand
from the documentation that they are storing information
used to optimize across multiple files.

My question is, is there any way to shove these in some directory so
I don't have them clutter up my working directory? The compilier
flag

-module

does this for the .mod files, but I can't find an equivalent one
for the .il files.

Thanks in advance
Matt

You don't say which version of Intel Fortran you are using. Version 8.0 allows
the IL to be stored in the .obj files so that you can put them in libraries,
etc. For details, read the chapter on Interprocedural Optimization in Volume
II of the Intel Fortran User's Guide. The switch -ipo_obj will be of use
here, but please read the manual because there's more involved than just
adding the switch.
