From 9285c096fe4b8810a290875d73d35a4496e7c4b3 Mon Sep 17 00:00:00 2001 From: Martin Storsjo Date: Thu, 1 Nov 2012 11:15:28 +0200 Subject: Revert "Use __builtin_clz instead of default implementation of fixnormz on GCC" This reverts commit e036dbc8eb7d5fdd02dc70faff20e9ac3e2989ca. Upstream took __builtin_clz in use (in the new header libFDK/include/x86/clz_x86.h, together with an alternative implementation for MSVC), so this change can be dropped to minimize the differences. --- libFDK/include/clz.h | 12 ------------ 1 file changed, 12 deletions(-) (limited to 'libFDK') diff --git a/libFDK/include/clz.h b/libFDK/include/clz.h index d276002..38c5073 100644 --- a/libFDK/include/clz.h +++ b/libFDK/include/clz.h @@ -118,11 +118,6 @@ inline INT fixnormz_S (SHORT a) { return fixnormz_D((INT)(a)); } -#elif defined(__GNUC__) -inline INT fixnormz_S (SHORT a) -{ - return a ? __builtin_clz(a) : 16; -} #else inline INT fixnormz_S (SHORT a) { @@ -139,12 +134,6 @@ inline INT fixnormz_S (SHORT a) #endif #if !defined(FUNCTION_fixnormz_D) -#if defined(__GNUC__) -inline INT fixnormz_D (LONG a) -{ - return a ? __builtin_clz(a) : 32; -} -#else inline INT fixnormz_D (LONG a) { INT leadingBits = 0; @@ -157,7 +146,6 @@ inline INT fixnormz_D (LONG a) return (leadingBits); } #endif -#endif /***************************************************************************** -- cgit v1.2.3
