ARM64: Unable to decode `fmlalb`, `fmlalt`, `fmlallbb`, `fmlallbt`, `fmlalltb`, `fmlalltt` instructions
TIHan opened this issue · comments
The following instructions are not able to be decoded with cstool:
FMLALB <Zda>.H, <Zn>.B, <Zm>.B[<imm>]FMLALT <Zda>.H, <Zn>.B, <Zm>.B[<imm>]FMLALLBB <Zda>.S, <Zn>.B, <Zm>.B[<imm>]FMLALLBT <Zda>.S, <Zn>.B, <Zm>.B[<imm>]FMLALLTB <Zda>.S, <Zn>.B, <Zm>.B[<imm>]FMLALLTT <Zda>.S, <Zn>.B, <Zm>.B[<imm>]
The decoder just fails and stops.
Those ones seem to be added with LLVM-18. At least this is the version I can find the first regression tests in LLVM for. We will update it after the #2231 is done. Which should be this month, if anything goes by plan.
Thanks for the update!
