From 69da3c9e87e0a692e79db0615a53782e4198dbf0 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Mon, 7 Jan 2019 09:04:29 -0800 Subject: soft-fp: Properly check _FP_W_TYPE_SIZE [BZ #24066] quad.h have #if _FP_W_TYPE_SIZE < 64 union _FP_UNION_Q { Use 4 _FP_W_TYPEs } #else union _FP_UNION_Q { Use 2 _FP_W_TYPEs } #endif Replace #if (2 * _FP_W_TYPE_SIZE) < _FP_FRACBITS_Q with #if _FP_W_TYPE_SIZE < 64 to check whether 4 or 2 _FP_W_TYPEs are used for IEEE quad precision. Tested with build-many-glibcs.py.
