Thanks. Now it probably became apparent that I need a vehicle to help
me with the S/390 FPR numbering.
The existing constant (FPR2_REGNUM) was wrong as well as my new macros
(>F8).
I'll commit the attached patch after successful testing.

2013-07-08 Andreas Krebbel <Andreas.Krebbel@de.ibm.com>
* config/s390/s390.c: Replace F*_REGNUM with FPR*_REGNUM.
* config/s390/s390.h: Remove F*_REGNUM macro definitions.
* config/s390/s390.md: Define FPR*_REGNUM constants.
Fix FPR2_REGNUM constant (18 -> 17).
("*trunc<BFP:mode><DFP_ALL:mode>2")
("*trunc<DFP_ALL:mode><BFP:mode>2")
("trunc<BFP:mode><DFP_ALL:mode>2")
("trunc<DFP_ALL:mode><BFP:mode>2")
("*extend<BFP:mode><DFP_ALL:mode>2")
("*extend<DFP_ALL:mode><BFP:mode>2")
("extend<BFP:mode><DFP_ALL:mode>2")
("extend<DFP_ALL:mode><BFP:mode>2"): Replace FPR2_REGNUM with
FPR4_REGNUM.
