2003-12-17 Carlos O'Donell <carlos@baldric.uwo.ca> * sysdeps/hppa/fpu/fclrexcpt.c (feclearexcept): Right shift FE_ALL_EXCEPT before complimenting. * sysdeps/hppa/fpu/fegetenv.c (fegetenv): Use asm 'ma,' completer, and gcc '+r' constraint. * sysdeps/hppa/fpu/feholdexcpt.c (feholdexcept): Likewise. * sysdeps/hppa/fpu/fesetenv.c (fesetenv): Likewise. * sysdeps/hppa/fpu/feupdateenv.c (feupdateenv): Read raised exception bits, OR with envp, pass to fesetenv. * sysdeps/hppa/fpu/fraiseexcpt.c (feraiseexcept): Add delayed exception flushing, FE_UNDERFLOW is DBL_MIN/3.0, FE_INEXACT is triggered by M_PI/69.69 converted to single precision. * sysdeps/hppa/fpu/fsetexcptflg.c (fesetexceptflag): Set enable bits not raised exception bits. * sysdeps/hppa/Makefile: Add dl-symaddr and dl-fptr to the correct build strings. * sysdeps/hppa/dl-fptr.h: New file. * sysdeps/hppa/dl-fptr.c: Removed. * sysdeps/hppa/dl-symaddr.c (_dl_symbol_address): Use _dl_make_ftpr, remove const qualifier for map. (_dl_function_address): Removed. * sysdeps/hppa/dl-lookupcfg.h: DL_LOOKUP_ADDRESS must clear PLABEL32 bits, define DL_AUTO_FUNCTION_ADDRESS and DL_STATIC_FUNCTION_ADDRESS, DL_DT_INIT_ADDRESS and DL_DT_FINI_ADDRESS use the previous two macros. * misc/mntent_r.c: Change encoding to match recently changed decoder.
