From 53994f12633b863eb833fc3b1f6971ae8de61ff8 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Wed, 6 Dec 2017 13:42:58 +0000 Subject: Make some ldbl-128, ldbl-128ibm arrays const. I noticed that an x86_64 build of libm unexpectedly contained more non-constant data than an older version (before _Float128 support) did. The problem is non-const arrays in the ldbl-128 j0l and j1l implementations; this patch makes those arrays, and the corresponding ldbl-128ibm ones, const. Tested for x86_64, and tested compilation for powerpc with build-many-glibcs.py. * sysdeps/ieee754/ldbl-128/e_j0l.c (Y0_2N): Make const. (Y0_2D): Likewise. * sysdeps/ieee754/ldbl-128/e_j1l.c (Y0_2N): Likewise. (Y0_2D): Likewise. * sysdeps/ieee754/ldbl-128ibm/e_j0l.c (Y0_2N): Likewise. (Y0_2D): Likewise. * sysdeps/ieee754/ldbl-128ibm/e_j1l.c (Y0_2N): Likewise. (Y0_2D): Likewise. --- sysdeps/ieee754/ldbl-128/e_j0l.c | 4 ++-- sysdeps/ieee754/ldbl-128/e_j1l.c | 4 ++-- 2 files changed, 4 insertions(+), 4 deletions(-) (limited to 'sysdeps/ieee754/ldbl-128') diff --git a/sysdeps/ieee754/ldbl-128/e_j0l.c b/sysdeps/ieee754/ldbl-128/e_j0l.c index fb8d351..9190e27 100644 --- a/sysdeps/ieee754/ldbl-128/e_j0l.c +++ b/sysdeps/ieee754/ldbl-128/e_j0l.c @@ -796,7 +796,7 @@ strong_alias (__ieee754_j0l, __j0l_finite) Peak absolute error 1.7e-36 (relative where Y0 > 1) 0 <= x <= 2 */ #define NY0_2N 7 -static _Float128 Y0_2N[NY0_2N + 1] = { +static const _Float128 Y0_2N[NY0_2N + 1] = { L(-1.062023609591350692692296993537002558155E19), L(2.542000883190248639104127452714966858866E19), L(-1.984190771278515324281415820316054696545E18), @@ -807,7 +807,7 @@ static _Float128 Y0_2N[NY0_2N + 1] = { L(8.230845651379566339707130644134372793322E6), }; #define NY0_2D 7 -static _Float128 Y0_2D[NY0_2D + 1] = { +static const _Float128 Y0_2D[NY0_2D + 1] = { L(1.438972634353286978700329883122253752192E20), L(1.856409101981569254247700169486907405500E18), L(1.219693352678218589553725579802986255614E16), diff --git a/sysdeps/ieee754/ldbl-128/e_j1l.c b/sysdeps/ieee754/ldbl-128/e_j1l.c index 6fc69fa..e7af40e 100644 --- a/sysdeps/ieee754/ldbl-128/e_j1l.c +++ b/sysdeps/ieee754/ldbl-128/e_j1l.c @@ -815,7 +815,7 @@ strong_alias (__ieee754_j1l, __j1l_finite) Peak relative error 6.2e-38 0 <= x <= 2 */ #define NY0_2N 7 -static _Float128 Y0_2N[NY0_2N + 1] = { +static const _Float128 Y0_2N[NY0_2N + 1] = { L(-6.804415404830253804408698161694720833249E19), L(1.805450517967019908027153056150465849237E19), L(-8.065747497063694098810419456383006737312E17), @@ -826,7 +826,7 @@ static _Float128 Y0_2N[NY0_2N + 1] = { L(9.541172044989995856117187515882879304461E5), }; #define NY0_2D 7 -static _Float128 Y0_2D[NY0_2D + 1] = { +static const _Float128 Y0_2D[NY0_2D + 1] = { L(3.470629591820267059538637461549677594549E20), L(4.120796439009916326855848107545425217219E18), L(2.477653371652018249749350657387030814542E16), -- cgit v1.1
