From 9a1eb39a6018cdf98de8518a9dd68c67098b6dcb Mon Sep 17 00:00:00 2001 From: Eric Andersen Date: Sun, 25 Aug 2002 22:04:43 +0000 Subject: Kill the HAS_LONG_LONG option. It really did not make a lot of sense to exclude it, gcc always supports long long, and we never fully excluded long long anyways (off64_t for example). -Erik --- libc/stdlib/drand48-iter.c | 39 --------------------------------------- 1 file changed, 39 deletions(-) (limited to 'libc/stdlib/drand48-iter.c') diff --git a/libc/stdlib/drand48-iter.c b/libc/stdlib/drand48-iter.c index 3247bafbd..858253b5a 100644 --- a/libc/stdlib/drand48-iter.c +++ b/libc/stdlib/drand48-iter.c @@ -27,7 +27,6 @@ struct drand48_data __libc_drand48_data; -#ifdef __UCLIBC_HAS_LONG_LONG__ int __drand48_iterate (unsigned short int xsubi[3], struct drand48_data *buffer) { @@ -57,41 +56,3 @@ __drand48_iterate (unsigned short int xsubi[3], struct drand48_data *buffer) return 0; } -#else -int -__drand48_iterate (unsigned short int xsubi[3], struct drand48_data *buffer) -{ - uint32_t X0, X1; - uint32_t result0, result1; - - /* Initialize buffer, if not yet done. */ - if (unlikely(!buffer->__init)) - { - buffer->__a1 = 0x5; - buffer->__a0 = 0xdeece66d; - buffer->__c = 0xb; - buffer->__init = 1; - } - - /* Do the real work.
