2001-08-11 Ulrich Weigand <uweigand@de.ibm.com>
* s390.c, s390.h, s390.md, s390-protos.h, linux.h, t-linux:
Clean up code: add missing comments and prototypes, fix warnings,
remove obsolete code, fix spacing to conform to coding style.
2001-08-11 Ulrich Weigand <uweigand@de.ibm.com>
* config/s390/s390.c (targetm): Define TARGET_ASM_OPEN_PAREN
and TARGET_ASM_CLOSE_PAREN.
(regclass_map): CC register belongs to class NO_REGS.
