From c624d23260d5c136bebdd3a0734876527cedc505 Mon Sep 17 00:00:00 2001 From: Tulio Magno Quites Machado Filho Date: Tue, 29 May 2018 17:52:24 -0300 Subject: Add a generic scalb implementation This is a preparatory patch to enable building a _Float128 variant to ease reuse when building a _Float128 variant to alias this long double only symbol. Notably, stubs are added where missing to the native _Float128 sysdep dir to prevent building these newly templated variants created inside the build directories. Also noteworthy are the changes around LIBM_SVID_COMPAT. These changes are not intuitive. The templated version is only enabled when !LIBM_SVID_COMPAT, and the compat version is predicated entirely on LIBM_SVID_COMPAT. Thus, exactly one is stubbed out entirely when building. The nldbl scalb compat files are updated to account for this. Likewise, fixup the reuse of m68k's e_scalb{f,l}.c to include it's override of e_scalb.c. Otherwise, the search path finds the templated copy in the build directory. This could be futher simplified by providing an overridden template, but I lack the hardware to verify. --- sysdeps/ieee754/ldbl-opt/w_scalb_compat.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'sysdeps/ieee754/ldbl-opt/w_scalb_compat.c') diff --git a/sysdeps/ieee754/ldbl-opt/w_scalb_compat.c b/sysdeps/ieee754/ldbl-opt/w_scalb_compat.c index f6d53a5ba5..56735e825e 100644 --- a/sysdeps/ieee754/ldbl-opt/w_scalb_compat.c +++ b/sysdeps/ieee754/ldbl-opt/w_scalb_compat.c @@ -1,5 +1,7 @@ #include #include -#if LONG_DOUBLE_COMPAT(libm, GLIBC_2_0) +#if LIBM_SVID_COMPAT +# if LONG_DOUBLE_COMPAT(libm, GLIBC_2_0) compat_symbol (libm, __scalb, scalbl, GLIBC_2_0); +# endif #endif -- cgit 1.4.1
