Pull up following revision(s) (requested by martin in ticket #416): distrib/sets/lists/comp/md.hppa: revision 1.3 include/fenv.h: revision 1.13 via patch lib/libm/Makefile: revision 1.168 lib/libm/arch/hppa/fenv.c: revisions 1.1, 1.2 sys/arch/hppa/include/Makefile: revision 1.12 sys/arch/hppa/include/fenv.h: revisions 1.1, 1.2 sys/arch/hppa/include/ieeefp.h: revisions 1.5-1.7 tests/lib/libm/Makefile: revision 1.29 via patch fenv(3) support for hppa -- use unsigned over uint32_t so that this file works without stdint.h being included before hand. fixes mknative-gcc problems, and likely others. -- Properly separate fenv.h and ieeefp.h by moving all fenv defines over to the former. Now that they are decoupled, make rounding modes match the hardware bits. -- Simplify, now that rounding mode defines match the hardware bits. |
