From d5138cf4a8f2415d2d568adfd3f65d3cc5a0b736 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Thu, 10 Feb 2011 13:59:34 +0000 Subject: [PATCH] softfloat: Fix compilation failures with USE_SOFTFLOAT_STRUCT_TYPES Make softfloat compile with USE_SOFTFLOAT_STRUCT_TYPES defined, by adding and using new macros const_float16(), const_float32() and const_float64() so you can use array initializers in an array of float16/float32/float64 whether the types are bare or wrapped in the structs.
