Stafford Horne	ae440402f5	or1k: Remove 64-bit support, it's not used and it breaks 32-bit hosts Reported by Rich Felker when building on 32-bit hosts. Backwards jump negative offsets were not calculated correctly due to improper 32-bit to 64-bit zero-extension. The 64-bit fields are present because we are mixing 32-bit and 64-bit architectures in our cpu descriptions. Removing 64-bit fixes the issue. We don't use 64-bit, there is an architecture spec for 64-bit but no implementations or simulators. My thought is if we need them in the future we should do the proper work to support both 32-bit and 64-bit implementations co-existing then. cpu/ChangeLog: yyyy-mm-dd Stafford Horne <shorne@gmail.com> PR 25184 * or1k.cpu (arch or1k): Remove or64 and or64nd machs.

Stafford Horne	6ce26ac7c3	cpu/or1k: Add support for orfp64a32 spec This patch adds support for OpenRISC 64-bit FPU operations on 32-bit cores by using register pairs. The functionality has been added to OpenRISC architecture specification version 1.3 as per architecture proposal 14[0]. For supporting assembly of both 64-bit and 32-bit precision instructions we have defined CGEN_VALIDATE_INSN_SUPPORTED. This allows cgen to use 64-bit bit architecture assembly parsing on 64-bit toolchains and 32-bit architecture assembly parsing on 32-bit toolchains. Without this the assembler has issues parsing register pairs. This patch also contains a few fixes to the symantics for existing OpenRISC single and double precision FPU operations.
