From 3352b62bebfd1e5c2e9961f481df968ab317d78d Mon Sep 17 00:00:00 2001 From: NetBSD project Date: Thu, 30 Jul 2015 09:50:51 +0000 Subject: StdLib/LibC: Add software floating point library from NetBSD Floating point processing is not supported on ARM for UEFI. In order to support UEFI applications in AppPkg we use this library to provide the required functionality. Changes as compared to the NetBSD version: - Formatting changes (tabs to spaces, DOS line endings etc). - Disable exceptions as described in the float_raise() function. - Disable definition of 'Symbolic Boolean literals' in milieu.h.
