2019-10-31	ext: Fix undefined-behavior bug in bitshift	Samuel Grayson
	If a small number or zero is passed in, fp64_exp could be very negative (-1000 for example). The intent of the line is to evaluate to zero in these cases, but what it actually did was bitshift right by 1000, which is undefined behavior (according to ubsan) that so happens to result in 0 on GCC/most architectures. This commit changes the code to check for cases where the bitshift is larger than the width of the integer.

2019-10-29	ext: Remove non-source files from fputils	Andreas Sandberg
	Remove the autoconf-based build system and GNU-style information files from fputils. After this change, we only keep the files we will need to integrate into gem5's main source tree.

	This patch updates fputils to the latest revision (6a47fd8358) from the upstream repository (github.com/andysan/fputils). Most notably, this includes changes that export a limited set of 64-bit float manipulation and avoids a warning about unused 64-bit floats in clang.
2013-10-02	ext: Fix fputils compiler flags to ensure ISO C99	Andreas Hansson
	The fp code relies on C99, and depending on gcc version, the default is to use c89. This patch adds -std=c99 when using gcc to ensure the code is compiled in ISO C99 mode.
