--- Comment #1 from Carl Love <c...@us.ibm.com> --- Created attachment 146589 --> https://bugs.kde.org/attachment.cgi?id=146589&action=edit Patch to change ACC to overlay VSRs Initial ACC support was implemented to use a separate register file, but in practice (ISA 3.1) the hardware implementation logically overlays over the existing VSR registers. This may change in future hardware, so the current implementation assumes ACC and VSRs logically contain the same data, but code remains in place to support future implementations that may require a separate register file. The patch reworks the code to support the ACC as implemented as a logical mapping over the VSR registers, and lays groundwork for a future implementation utilizing a separate register file. There is a single boolean variable, ACC_mapped_on_VSR, that can be set in disInstr_PPC_WRK(), based on the ISA being used, to select which implementation model to use. -- You are receiving this mail because: You are watching all bug changes.
