From: Gabe Black Date: Fri, 19 Oct 2018 00:50:42 +0000 (-0700) Subject: sparc: Get rid of some register type definitions. X-Git-Tag: v19.0.0.0~1236 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1ab1500dfd0cb64b2fef7fb5e0f9e1fa007d2481;p=gem5.git sparc: Get rid of some register type definitions. These are IntReg, FloatReg, FloatRegBits, and MiscReg. These have been supplanted by the global types RegVal and FloatRegVal.
