That Was it, thank you very much!

The issue (DICompileUnit not listed in llvm.dbg.cu) was caused by Clang'sRpass=loop-vectorize option. I'm not clear why it would cause bitcode process to fail, since all appleTVs should support Neon instruction. removing loop-vectorize has addressed it, but not optimal.

I'm getting this errors in 12.5 (M1) but not in 12.2 (Intel) , both stuck in "processing" on AppStoreConnect submit during thinning stage. Adhoc export doesn't fail in 12.2 but fails in 12.5, but 12.2 does not help. I'm stuck for a week now with no way to submit App with bitcode enabled( required for tvOS). No external/third party frameworks are in the project. _DICompileUnit not listed in llvm.dbg.cu !143 = distinct !DICompileUnit(language: DW_LANG_C_plus_plus_11, file: !5, producer: "_hidden#39", isOptimized: true, runtimeVersion: 0, emissionKind: NoDebug, enums: !10, nameTableKind: None, sysroot: "_hidden#40", sdk: "_hidden#41") ld: warning: Invalid debug info found, debug info will be stripped DICompileUnit not listed in llvm.dbg.cu !1429 = distinct !DICompileUnit(language: DW_LANG_C_plus_plus_11, file: !5, producer: "_hidden#39", isOptimized: true, runtimeVersion: 0, emissionKind: NoDebug, enums: !10, nameTableKind: None, sysroot: "_hidden#40", sdk: "_hidden#41") ld: warning: Invalid debug info found, debug info will be stripped DICompileUnit not listed in llvm.dbg.cu_

Was it resolved? I'm still getting this error on M1
