* sysdeps/sparc/jmp_buf.h: Rewritten; use array of ints, not struct. * sysdeps/sparc/setjmp.S: Rewritten; store %fp value as well. * sysdeps/sparc/__longjmp.S: Rewritten; unwind frames one by one with `restore' until the target frame is hit. Sun Mar 10 20:29:40 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/unix/sysv/linux/sigsuspend.c: New file. * sysdeps/unix/sysv/linux/syscalls.list: Remove sigsuspend, add s_sigsuspend. Thu Mar 7 21:30:58 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * Makerules (+make-deps, sed-remove-objpfx): Quote periods on the left side of sed substitutions. Sun Mar 10 16:58:10 1996 Ulrich Drepper <drepper@gnu.ai.mit.edu> * stdio-common/printf_fp.c (hack_digit): __mpn_normal_size is not available anymore. Do it ourselves. * sysdeps/unix/sysv/linux/i386/fpu_control.h (_FPU_SETCW): Correct GCC `asm' syntax. * stdio-common/Makefile (tests): Add tst-ungetc. * stdio-common/tst-ungetc.c: New test from drepper. * stdio-common/tstscanf.c (main): New %[ test case from drepper. * sysdeps/libm-ieee754/s_scalbn.c (scalbn): Rename to __scalbn; somehow this was missed, though the weak alias is already there.
