Update.
1998-08-23 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/i386/Versions [GLIBC_2.1]: Add __modify_ldt and modify_ldt. * sysdeps/unix/sysv/linux/i386/syscalls.list: Add modify_ldt. * sysdeps/unix/sysv/linux/i386/sysdep.h (SYSCALL_ERROR_HANDLER): Use orl $-1 instead of movl $-1 to save two bytes. * sysdeps/unix/sysv/linux/i386/i686/sysdep.h (SYSCALL_ERROR_HANDLER): Likewise. 1998-08-17 H.J. Lu <hjl@gnu.org> * libio/Versions (_IO_do_write, _IO_file_attach, _IO_file_close_it, _IO_file_finish, _IO_file_fopen, _IO_file_init, _IO_file_overflow, _IO_file_seekoff, _IO_file_setbuf, _IO_file_sync, _IO_file_underflow, _IO_file_write, _IO_file_xsputn): Added to GLIBC_2.1. * libio/fileops.c (_IO_do_write, _IO_file_attach, _IO_file_close_it, _IO_file_finish, _IO_file_fopen, _IO_file_init, _IO_file_overflow, _IO_file_seekoff, _IO_file_setbuf, _IO_file_sync, _IO_file_underflow, _IO_file_write, _IO_file_xsputn): Change the prefix to "_IO_new_". Added to GLIBC_2.1. * libio/libioP.h (_IO_do_write, _IO_file_attach, _IO_file_close_it, _IO_file_finish, _IO_file_fopen, _IO_file_init, _IO_file_overflow, _IO_file_seekoff, _IO_file_setbuf, _IO_file_sync, _IO_file_underflow, _IO_file_write, _IO_file_xsputn): Add prototypes for the prefix "_IO_new_". * libio/oldfileops.c (_IO_do_write, _IO_file_attach, _IO_file_close_it, _IO_file_finish, _IO_file_fopen, _IO_file_init, _IO_file_overflow, _IO_file_seekoff, _IO_file_setbuf, _IO_file_sync, _IO_file_underflow, _IO_file_write, _IO_file_xsputn): Added to GLIBC_2.0. 1998-08-23 Richard Henderson <rth@cygnus.com> * Makeconfig (LDFLAGS): Remove. * csu/initfini.c: Return to .text before __gmon_start__. * elf/elf.h (EM_FAKE_ALPHA): Rename from EM_OLD_ALPHA. (STO_MIPS_*): Rename from STO_*. (STB_MIPS_SPLIT_COMMON): Rename from STB_SPLIT_COMMON. (STO_ALPHA_NOPV, STO_ALPHA_STD_GPLOAD): New. * math/atest-exp.c (mpn_bitsize): Fix bit location calculation. (main): e3s is negative on zero. * math/atest-exp2.c: Likewise. * math/atest-sincos.c: Likewise. 1998-08-23 Andreas Jaeger <aj@arthur.rhein-neckar.de> * Makerules (install): Add comment about absolute paths. 1998-08-23 Ulrich Drepper <drepper@cygnus.com> * libio/vsnprintf.c (_IO_vsnprintf): Set first byte of destination array to NUL to handle maxlen==1 case correctly. Patch by HJ Lu. 1998-08-23 Richard Henderson <rth@cygnus.com>
