…lvm#68429) After calling arm_sme_state, the -S assembly would show clang generating a “tbz xN, #0, Lbb”. However, disassembling it showed that it was actually encoded as “tbz xN, #32, Lbb”. The issue is that for TBZ, if you want a bit offset <32 you need to use the W variant, since the instruction overloads the top bit of the immediate.

While lowering (#pragma omp target update from), clang's generated .omp_task_entry. is setting up 9 arguments while calling __tgt_target_data_update_nowait_mapper. At the same time, in __tgt_target_data_update_nowait_mapper, call to targetData<TaskAsyncInfoWrapperTy>() is converted to a sibcall assuming it has the argument count listed in the signature. AARCH64 asm sequence for this is as follows (removed unrelated insns): ` .omp_task_entry..108: sub sp, sp, #32 stp x29, x30, sp, #16 // 16-byte Folded Spill add x29, sp, #16 str x8, sp, #8. // stack canary str xzr, [sp] bl __tgt_target_data_update_nowait_mapper __tgt_target_data_update_nowait_mapper: sub sp, sp, #32 stp x29, x30, sp, #16 // 16-byte Folded Spill add x29, sp, #16 str x8, sp, #8 // stack canary // Sibcall argument setup adrp x8, :got:_Z16targetDataUpdateP7ident_tR8DeviceTyiPPvS4_PlS5_S4_S4_R11AsyncInfoTyb ldr x8, [x8, :got_lo12:_Z16targetDataUpdateP7ident_tR8DeviceTyiPPvS4_PlS5_S4_S4_R11AsyncInfoTyb] stp x9, x8, x29, #16 adrp x8, .L.str.8 add x8, x8, :lo12:.L.str.8 str x8, x29, #32. <==.

This issue can be credited to discrepancy of __tgt_target_data_update_nowait_mapper signature in openmp/libomptarget/include/omptarget.h taking 13 arguments while clang/lib/CodeGen/CGOpenMPRuntime.cpp and llvm/include/llvm/Frontend/OpenMP/OMPKinds.def taking only 9 arguments. This patch modifies __tgt_target_data_update_nowait_mapper signature to match .omp_task_entry usage(and other 2 files mentioned above).

The worst possible case for a double literal goes like: ``` mov ... movk ..., lsl #16 movk ..., lsl #32 movk ..., lsl #48 fmov ... ``` The limit of 5 in the code gives the impression that `Insn` includes all instructions including the `fmov`, but that's not true. It only counts the integer moves. This led me astray on some other work in this area.
