From fd20bf61eac3a3458694db9c476f54abef0077ea Mon Sep 17 00:00:00 2001 From: ian Date: Sat, 17 May 2014 22:19:16 +0000 Subject: MFC 264696, 264721, Add the deprecated fp{get,set}* functions, a few ports use them. Rename the fp{get,set}* files so they no longer conflict with the softfloat version of these files. --- lib/libc/arm/gen/fpgetround_vfp.c | 47 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) create mode 100644 lib/libc/arm/gen/fpgetround_vfp.c (limited to 'lib/libc/arm/gen/fpgetround_vfp.c') diff --git a/lib/libc/arm/gen/fpgetround_vfp.c b/lib/libc/arm/gen/fpgetround_vfp.c new file mode 100644 index 0000000..ed94388 --- /dev/null +++ b/lib/libc/arm/gen/fpgetround_vfp.c @@ -0,0 +1,47 @@ +/* + * Copyright (C) 2014 Andrew Turner + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
