2004-12-29 Jakub Jelinek <jakub@redhat.com> * sysdeps/ia64/fpu/libm_support.h (__libm_error_support): Use libc_hidden_proto instead of HIDDEN_PROTO. * sysdeps/ia64/fpu/libm-symbols.h (HIDDEN_PROTO): Remove. (__libm_error_support): If ASSEMBLER and in libc, define to HIDDEN_JUMPTARGET(__libm_error_support). 2004-12-28 David Mosberger <davidm@hpl.hp.com> * sysdeps/ia64/fpu/Makefile (duplicated-routines): New macro. (sysdep_routines): Replace libm_ldexp{,f,l} and libm_scalbn{,f,l} with $(duplicated-routines).
