Intel® Fortran Compiler 16.0 User and Reference Guide
Determines whether a fat link-time optimization (LTO) object, containing both intermediate language and object code, is generated during an interprocedural optimization compilation (-c –ipo).
Linux: | -ffat-lto-objects -fno-fat-lto-objects |
OS X: | None |
Windows: | None |
None
-ffat-lto-objects |
When –c –ipo is specified, the compiler generates a fat link-time optimization (LTO) object that has both a true object and a discardable intermediate language section. |
This option determines whether a fat link time optimization (LTO) object, containing both intermediate language and object code, is generated during an interprocedural optimization compilation (-c –ipo).
During an interprocedural optimization compilation (-c –ipo), the following occurs:
If you specify -ffat-lto-objects, the compiler generates a fat link-time optimization (LTO) object that has both a true object and a discardable intermediate language section. This enables both link-time optimization (LTO) linking and normal linking.
If you specify -fno-fat-lto-objects, the compiler generates a fat link-time optimization (LTO) object that only has a discardable intermediate language section; no true object is generated. This option may improve compilation time.

This option is provided for compatibility with gcc. For more information about this option, see the gcc documentation.
Intel's intermediate language representation is not compatible with gcc’s intermediate language representation.
