URL: https://github.com/llvm/llvm-project/commit/b516ca061838e2cb8b48b31ee113e3c4aae7e7d5 DIFF: https://github.com/llvm/llvm-project/commit/b516ca061838e2cb8b48b31ee113e3c4aae7e7d5.diff LOG: Revert "Reland: [DWARF] Allow cross-CU references of subprogram definitions" ... as well as: Revert "[DWARF] Defer creating declaration DIEs until we prepare call site info" This reverts commit fa4701e1979553c2df61698ac1ac212627630442. This reverts commit 79daafc90308787b52a5d3a7586e82acd5e374b3. There have been reports of this assert getting hit: CalleeDIE && "Could not find DIE for call site entry origin (cherry picked from commit 802bec896171997a7b73dde3857712e0eedeabc1) Added: Modified: llvm/lib/CodeGen/AsmPrinter/DwarfCompileUnit.cpp llvm/lib/CodeGen/AsmPrinter/DwarfDebug.cpp llvm/lib/CodeGen/AsmPrinter/DwarfDebug.h llvm/lib/CodeGen/AsmPrinter/DwarfUnit.cpp llvm/test/DebugInfo/MIR/AArch64/dbgcall-site-orr-moves.mir llvm/test/DebugInfo/MIR/X86/debug-call-site-param.mir Removed: llvm/test/DebugInfo/AArch64/unretained-declaration-subprogram.ll llvm/test/DebugInfo/X86/lto-cross-cu-call-origin-ref.ll ################################################################################ diff --git a/llvm/lib/CodeGen/AsmPrinter/DwarfCompileUnit.cpp b/llvm/lib/CodeGen/AsmPrinter/DwarfCompileUnit.cpp index 38011102c7b3..e97bcd62e8c7 100644 --- a/llvm/lib/CodeGen/AsmPrinter/DwarfCompileUnit.cpp +++ b/llvm/lib/CodeGen/AsmPrinter/DwarfCompileUnit.cpp @@ -968,8 +968,8 @@ DIE &DwarfCompileUnit::constructCallSiteEntryDIE( addAddress(CallSiteDIE, getDwarf5OrGNUAttr(dwarf::DW_AT_call_target), MachineLocation(CallReg)); } else { - DIE *CalleeDIE = getDIE(CalleeSP); - assert(CalleeDIE && "Could not find DIE for call site entry origin"); + DIE *CalleeDIE = getOrCreateSubprogramDIE(CalleeSP); + assert(CalleeDIE && "Could not create DIE for call site entry origin"); addDIEEntry(CallSiteDIE, getDwarf5OrGNUAttr(dwarf::DW_AT_call_origin), *CalleeDIE); } diff --git a/llvm/lib/CodeGen/AsmPrinter/DwarfDebug.cpp b/llvm/lib/CodeGen/AsmPrinter/DwarfDebug.cpp index fa6800de7955..6e643ad26410 100644 --- a/llvm/lib/CodeGen/AsmPrinter/DwarfDebug.cpp +++ b/llvm/lib/CodeGen/AsmPrinter/DwarfDebug.cpp @@ -540,14 +540,6 @@ void DwarfDebug::constructAbstractSubprogramScopeDIE(DwarfCompileUnit &SrcCU, } } -DIE &DwarfDebug::constructSubprogramDefinitionDIE(const DISubprogram *SP) { - DICompileUnit *Unit = SP->getUnit(); - assert(SP->isDefinition() && "Subprogram not a definition"); - assert(Unit && "Subprogram definition without parent unit"); - auto &CU = getOrCreateDwarfCompileUnit(Unit); - return *CU.getOrCreateSubprogramDIE(SP); -} - /// Try to interpret values loaded into registers that forward parameters /// for \p CallMI.
