v1 -> v2:
* Bring the MEM into the operand for cv.elw. The new predicate is
move_operand.
* Add comment to riscv.md detailing why corev.md must appear before
the generic riscv instructions.
v2 -> v3:
* Merged patterns for CORE-V branch immediate and generic RISC-V so to
supress the generic patterns if XCVbi is available.
This patch series presents the comprehensive implementation of the ELW and BI
extension for CORE-V.
Tested with riscv-gnu-toolchain on binutils, ld, gas and gcc testsuites to
ensure its correctness and compatibility with the existing codebase.
However, your input, reviews, and suggestions are invaluable in making this
extension even more robust.
The CORE-V builtins are described in the specification [1] and work can be
found in the OpenHW group's Github repository [2].
