1997-04-01 00:37 Ulrich Drepper <drepper@cygnus.com> * math/Makefile: Prevent inlining for test-{float,double,longdouble}. * math/libm-test.c (initialize): Make strings unique and force values to memory. * posix/regex.c: Debug debugging code. * sysdeps/i386/asm-syntax.h: Define `L' macro to emit correct syntax for local label. * sysdeps/i386/add_n.S: Use correct local label syntax for the binary format. * sysdeps/i386/addmul_1.S: Likewise. * sysdeps/i386/lshift.S: Likewise. * sysdeps/i386/memchr.S: Likewise. * sysdeps/i386/memset.S: Likewise. * sysdeps/i386/mul_1.S: Likewise. * sysdeps/i386/rshift.S: Likewise. * sysdeps/i386/stpcpy.S: Likewise. * sysdeps/i386/stpncpy.S: Likewise. * sysdeps/i386/strchr.S: Likewise. * sysdeps/i386/strcspn.S: Likewise. * sysdeps/i386/strlen.S: Likewise. * sysdeps/i386/strpbrk.S: Likewise. * sysdeps/i386/strrchr.S: Likewise. * sysdeps/i386/strspn.S: Likewise. * sysdeps/i386/strtok.S: Likewise. * sysdeps/i386/sub_n.S: Likewise. * sysdeps/i386/submul_1.S: Likewise. * sysdeps/i386/i486/strcat.S: Likewise. * sysdeps/i386/i486/strlen.S: Likewise. * sysdeps/i386/i586/add_n.S: Likewise. * sysdeps/i386/i586/addmul_1.S: Likewise. * sysdeps/i386/i586/lshift.S: Likewise. * sysdeps/i386/i586/memset.S: Likewise. * sysdeps/i386/i586/mul_1.S: Likewise. * sysdeps/i386/i586/rshift.S: Likewise. * sysdeps/i386/i586/strchr.S: Likewise. * sysdeps/i386/i586/strlen.S: Likewise. * sysdeps/i386/i586/sub_n.S: Likewise. * sysdeps/i386/i586/submul_1.S: Likewise. * sysdeps/stub/s_log2l.c: Correct function name. * time/africa: Updated from ADO tzdata1997e. * time/aantarctica: Likewise. * time/asia: Likewise. * time/australia: Likewise. * time/europe: Likewise. * time/northamerica: Likewise. * time/southamerica: Likewise. * time/private.h: Updated from ADO tzcode1997d. * time/scheck.c: Likewise. 1997-03-31 12:42 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/powerpc/Dist: Add kernel_*.h files. 1997-03-23 01:41 Geoff Keating <geoffk@ozemail.com.au> * sysdeps/powerpc/strlen.s: Rewrote for more speed. * string/tst-strlen.c: Also test various string alignments. 1997-03-19 06:11 Geoff Keating <geoffk@ozemail.com.au> * sysdeps/unix/sysv/linux/powerpc/statbuf.h: Removed. * sysdeps/unix/sysv/linux/powerpc/kernel_stat.h: Added. * sysdeps/powerpc/dl-machine.h (ELF_PREFERRED_ADDRESS): Assume program base address is 0x01800000 if we can't otherwise tell what it is. (elf_machine_rela): Replace `assertion failed' with real error messages. * sysdeps/powerpc/dl-machine.h: More comments, more GNU indenting. Put in extra parentheses to make explicit the relative precedence of + and >>. * sysdeps/powerpc/bsd-setjmp.S: Add `__setjmp' symbol so the tests pass. * sysdeps/powerpc/clone.S: Rewrite. Probably still doesn't work. * sysdeps/unix/sysv/linux/powerpc/sys/sysdep.h: Use .section "text" instead of .text. 1997-03-31 02:28 Ulrich Drepper <drepper@cygnus.com> * misc/tst-tsearch.c: Don't write to stderr, write to stdout instead. * inet/inet_ntoa.c (inet_ntoa): Complete rewrite. Now uses thread-specific memory in multi-threaded programs. * sysdeps/stub/s_exp2.c: New file. Stub version for exp2 function. * sysdeps/stub/s_exp2f.c: New file. * sysdeps/stub/s_exp2l.c: New file. Reported by a sun <asun@zoology.washington.edu>. * sysdeps/unix/sysv/linux/netatalk/atalk.h: Rename to... * sysdeps/unix/sysv/linux/netatalk/at.h: ...this. Suggested by a sun <asun@zoology.washington.edu>. 1997-03-30 14:53 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/netinet/ip_icmp.h: Add former contents of <netinet/icmp.h>. Patch by a sun <asun@zoology.washington.edu>. * sysdeps/powerpc/strlen.S: Added.
