This is a work-in-progress implementation of an assembler for M68k. Outstanding work: - Updating existing tests assembly syntax - Writing new tests for the assembler (and disassembler) I've left those until there's consensus that this approach is okay (I hope that's okay!). Questions I'm aware of: - Should this use Motorola or gas syntax? (At the moment it uses Motorola syntax.) - The disassembler produces a table at runtime for disassembly generated from the code beads. Is this okay? (This is less than ideal but as I mentioned in my llvm-dev post, it's quite complicated to write a table-gen parser for code beads.) Depends on D98519 Depends on D98532 Depends on D98534 Depends on D98535 Depends on D98536 Differential Revision: https://reviews.llvm.org/D98537

; At the moment, all encoding tests for M68k live in llvm/test/CodeGen/M68k/.
|
|
; This is the first test included as part of the AsmMatcher and lacks encoding checks.
|
|
; The current migration plan is to consolidate all of the encoding tests in this
|
|
; directory along with AsmMatcher/ Disassembler tests like the other platforms.
|
|
; For more information and status updates see bug #49865.
