From 1177c8babf74c7335c5f3bf09c45961bebeed6c6 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Tue, 12 Mar 1996 09:50:46 +0000 Subject: Tue Mar 12 04:42:01 1996 Roland McGrath * 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 * 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 * Makerules (+make-deps, sed-remove-objpfx): Quote periods on the left side of sed substitutions. Sun Mar 10 16:58:10 1996 Ulrich Drepper * 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. --- sysdeps/libm-ieee754/s_scalbn.c | 24 ++++++++++++------------ 1 file changed, 12 insertions(+), 12 deletions(-) (limited to 'sysdeps/libm-ieee754/s_scalbn.c') diff --git a/sysdeps/libm-ieee754/s_scalbn.c b/sysdeps/libm-ieee754/s_scalbn.c index 835f00ea77..6efaec07ac 100644 --- a/sysdeps/libm-ieee754/s_scalbn.c +++ b/sysdeps/libm-ieee754/s_scalbn.c @@ -5,7 +5,7 @@ * * Developed at SunPro, a Sun Microsystems, Inc. business. * Permission to use, copy, modify, and distribute this - * software is freely granted, provided that this notice + * software is freely granted, provided that this notice * is preserved. * ==================================================== */ @@ -14,10 +14,10 @@ static char rcsid[] = "$NetBSD: s_scalbn.c,v 1.8 1995/05/10 20:48:08 jtc Exp $"; #endif -/* +/* * scalbn (double x, int n) - * scalbn(x,n) returns x* 2**n computed by exponent - * manipulation rather than by actually performing an + * scalbn(x,n) returns x* 2**n computed by exponent + * manipulation rather than by actually performing an * exponentiation or a multiplication. */ @@ -35,9 +35,9 @@ huge = 1.0e+300, tiny = 1.0e-300; #ifdef __STDC__ - double scalbn (double x, int n) + double __scalbn (double x, int n) #else - double scalbn (x,n) + double __scalbn (x,n) double x; int n; #endif { @@ -46,20 +46,20 @@ tiny = 1.0e-300; k = (hx&0x7ff00000)>>20; /* extract exponent */ if (k==0) { /* 0 or subnormal x */ if ((lx|(hx&0x7fffffff))==0) return x; /* +-0 */ - x *= two54; + x *= two54; GET_HIGH_WORD(hx,x); - k = ((hx&0x7ff00000)>>20) - 54; + k = ((hx&0x7ff00000)>>20) - 54; if (n< -50000) return tiny*x; /*underflow*/ } if (k==0x7ff) return x+x; /* NaN or Inf */ - k = k+n; - if (k > 0x7fe) return huge*copysign(huge,x); /* overflow */ + k = k+n; + if (k > 0x7fe) return huge*__copysign(huge,x); /* overflow */ if (k > 0) /* normal result */ {SET_HIGH_WORD(x,(hx&0x800fffff)|(k<<20)); return x;} if (k <= -54) if (n > 50000) /* in case integer overflow in n+k */ - return huge*copysign(huge,x); /*overflow*/ - else return tiny*copysign(tiny,x); /*underflow*/ + return huge*__copysign(huge,x); /*overflow*/ + else return tiny*__copysign(tiny,x); /*underflow*/ k += 54; /* subnormal result */ SET_HIGH_WORD(x,(hx&0x800fffff)|(k<<20)); return x*twom54; -- cgit 1.4.1
