From bc4347b883e8175dadef77ed9e02ccaa5e8eba94 Mon Sep 17 00:00:00 2001
From: Stefan Weil <weil@mail.berlios.de>

Subject: [PATCH] arm host: fix compiler warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Compilation for arm (native or cross) results in this
warning:
fpu/softfloat-native.c: In function ‘float64_round_to_int’:
fpu/softfloat-native.c:387: error: control reaches end of non-void function
float64_round_to_int uses special assembler code for arm
and has no explicit return value.
As there is no obvious reason why arm should need special
code, all fpu related conditionals were removed.
The remaining code is standard (C99) and compiles for arm,
too.
