Alan Modra	0c115f8483	ubsan: m32c: left shift of negative value More nonsense fixing "bugs" with left shifts of signed values. Yes, the C standard does say this is undefined (and right shifts of signed values are implementation defined BTW) but in practice there is no problem with current machines. 1's complement is a thing of the past. cpu/ * m32c.cpu (f-src32-rn-unprefixed-QI): Shift before inverting.

Jose E. Marchesi	231097b03a	cpu,opcodes,gas: use %r0 and %r6 instead of %a and %ctf in eBPF disassembler This patch changes the eBPF CPU description to prefer the register names %r0 and %r6 instead of %a and %ctx when disassembling. This matches better with the current practice, vs. cBPF. It also updates the GAS tests in order to reflect this change. Tested in a x86_64 host. cpu/ChangeLog: 2019-07-19 Jose E.

Jose E.

Instead, they put the loaded value in %r0, implicitly. This patch fixes the CPU BPF description to not expect a 'dst' argument in these arguments, regenerates the corresponding files in opcodes, and updates the impacted GAS tests.

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.
