From 49547c68f9c2f0e524e64dc6ff8f43147907cae4 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Fri, 20 Apr 2001 06:06:55 +0000 Subject: Update. 2001-04-19 Alan Modra * Makerules (libc_pic.os): Add $(LDFLAGS-c_pic.os). * sysdeps/hppa/Makefile (LDFLAGS-c_pic.os): Define. (CFLAGS-.os): Remove. * sysdeps/unix/sysv/linux/hppa/sysdep.h (CALL_MCOUNT): Update comment. * sysdeps/unix/sysv/linux/hppa/sys/ucontext.h (NGREG, NFPREG, gregset): Correct for new kernel definitions. 2001-04-19 Alan Modra * sysdeps/hppa/elf/initfini.c: Change dlt reg save to r3 and generate unwind info by hand. 2001-04-19 Ulrich Drepper * sysdeps/unix/sysv/linux/powerpc/mmap64.c (__mmap64): Optimize a bit. * configure.in: Correct regular expression for msgfmt.
