From 15089e046b6c71bbefe29687fe4c7e569c9e1c03 Mon Sep 17 00:00:00 2001 From: "Paul E. Murphy" Date: Wed, 20 Jul 2016 15:20:51 -0500 Subject: ldbl-128: Rename 'long double' to '_Float128' Add a layer of macro indirection for long double files which need to be built using another typename. Likewise, add the L(num) macro used in a later patch to override real constants. These macros are only defined through the ldbl-128 math_ldbl.h header, thereby implicitly restricting these macros to machines which back long double with an IEEE binary128 format. Likewise, appropriate changes are made for the few files which indirectly include such ldbl-128 files. These changes produce identical binaries for s390x, aarch64, and ppc64. --- sysdeps/ieee754/ldbl-128/s_llrintl.c | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) (limited to 'sysdeps/ieee754/ldbl-128/s_llrintl.c') diff --git a/sysdeps/ieee754/ldbl-128/s_llrintl.c b/sysdeps/ieee754/ldbl-128/s_llrintl.c index 84fc576ab6..0e52757cdc 100644 --- a/sysdeps/ieee754/ldbl-128/s_llrintl.c +++ b/sysdeps/ieee754/ldbl-128/s_llrintl.c @@ -26,19 +26,19 @@ #include #include -static const long double two112[2] = +static const _Float128 two112[2] = { 5.19229685853482762853049632922009600E+33L, /* 0x406F000000000000, 0 */ -5.19229685853482762853049632922009600E+33L /* 0xC06F000000000000, 0 */ }; long long int -__llrintl (long double x) +__llrintl (_Float128 x) { int32_t j0; u_int64_t i0,i1; - long double w; - long double t; + _Float128 w; + _Float128 t; long long int result; int sx; @@ -52,7 +52,7 @@ __llrintl (long double x) { #if defined FE_INVALID || defined FE_INEXACT /* X < LLONG_MAX + 1 implied by J0 < 63. */ - if (x > (long double) LLONG_MAX) + if (x > (_Float128) LLONG_MAX) { /* In the event of overflow we must raise the "invalid" exception, but not "inexact". */ @@ -83,8 +83,8 @@ __llrintl (long double x) FE_INVALID must be raised and the return value is unspecified. */ #if defined FE_INVALID || defined FE_INEXACT - if (x < (long double) LLONG_MIN - && x > (long double) LLONG_MIN - 1.0L) + if (x < (_Float128) LLONG_MIN + && x > (_Float128) LLONG_MIN - 1.0L) { /* If truncation produces LLONG_MIN, the cast will not raise the exception, but may raise "inexact". */ @@ -92,7 +92,7 @@ __llrintl (long double x) feraiseexcept (t == LLONG_MIN ?
