libgcc/
|

* config.host (arm*-*-linux*, arm*-*-uclinux*, arm*-*-eabi*)
|
|
(arm*-*-symbianelf): Add arm/t-divmod-ef to tmake_file.
|
|
* Makefile.in (LIB2_DIVMOD_EXCEPTION_FLAGS): Set to previous
|
|
default if not set by a target-specific Makefile fragment.
|
|
(lib2-divmod-o, lib2-divmod-s-o): Use above.
|
|
* config/arm/t-divmod-ef: New.
