NFCI (#65457) m_x86_Features_Group always turn `mno-xxxx` into `-target-feature -xxxx`. In this case, we don't have `-gather/-scatter` but `+prefer-no-gather/scatter`. This patch solves unexpected warning when using `mno-gather/mno-scatter`: ``` '-gather' is not a recognized feature for this target (ignoring feature) '-scatter' is not a recognized feature for this target (ignoring feature) ``` Added: Modified: clang/include/clang/Driver/Options.td Removed: ################################################################################ diff --git a/clang/include/clang/Driver/Options.td b/clang/include/clang/Driver/Options.td index e6d8aed6aefc8d9..9a6e7e9929f5f2f 100644 --- a/clang/include/clang/Driver/Options.td +++ b/clang/include/clang/Driver/Options.td @@ -5846,9 +5846,9 @@ def mretpoline_external_thunk : Flag<["-"], "mretpoline-external-thunk">, Group< def mno_retpoline_external_thunk : Flag<["-"], "mno-retpoline-external-thunk">, Group<m_x86_Features_Group>; def mvzeroupper : Flag<["-"], "mvzeroupper">, Group<m_x86_Features_Group>; def mno_vzeroupper : Flag<["-"], "mno-vzeroupper">, Group<m_x86_Features_Group>; -def mno_gather : Flag<["-"], "mno-gather">, Group<m_x86_Features_Group>, +def mno_gather : Flag<["-"], "mno-gather">, Group<m_Group>, HelpText<"Disable generation of gather instructions in auto-vectorization(x86 only)">; -def mno_scatter : Flag<["-"], "mno-scatter">, Group<m_x86_Features_Group>, +def mno_scatter : Flag<["-"], "mno-scatter">, Group<m_Group>, HelpText<"Disable generation of scatter instructions in auto-vectorization(x86 only)">; } // let Flags = [TargetSpecific] _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
