| * sh: Storage class should be before const qualifierTobias Klauser2009-02-12
| | | | | | | | | | | | | | | | | | | | | | The C99 specification states in section 6.11.5: The placement of a storage-class specifier other than at the beginning of the declaration specifiers in a declaration is an obsolescent feature.

* sh: fcnvds fix with denormalized numbers on SH-4 FPU.Carmelo AMOROSO2009-01-28
| | | | | | | | | | | | | | | This fixes a bug in the FPU exception handler for the FCNVDS instruction. To get the register number the instruction is shifted right by 9, though it should be shifted right by 8.
