1# This test checks that we have a mapping between the B registers and their Codeview numbers.2# There is no 8 bit float type so this is a modified version of codeview-h-register.mir to3# have a B register in the location info but not the instructions. Which is incorrect4# but in ways this test does not care about.5#6# RUN: llc %s -mtriple=arm64-windows -filetype=obj -o %t --start-after=unpack-mi-bundles7# RUN: llvm-readobj --codeview %t | FileCheck %s --check-prefix=OBJ8#9# OBJ: LocalSym {10# OBJ: Kind: S_LOCAL (0x113E)11# OBJ: Type: __half (0x46)12# OBJ: Flags [ (0x1)13# OBJ: IsParameter (0x1)14# OBJ: ]15# OBJ: VarName: x16# OBJ: }17# OBJ: DefRangeRegisterSym {18# OBJ: Kind: S_DEFRANGE_REGISTER (0x1141)19# OBJ: Register: ARM64_B0 (0xE6)20# OBJ: MayHaveNoName: 021# OBJ: LocalVariableAddrRange {22# OBJ: OffsetStart: .text+0x023# OBJ: ISectStart: 0x024# OBJ: Range: 0x425# OBJ: }26# OBJ: }27#28--- |29 define internal fastcc i1 @test.fn(half %0) !dbg !4 {30 Entry:31 call void @llvm.dbg.value(metadata half %0, metadata !11, metadata !DIExpression()), !dbg !1332 %1 = fcmp une half 0xH0000, %0, !dbg !1433 ret i1 %134 }35 36 ; Function Attrs: nocallback nofree nosync nounwind readnone speculatable willreturn37 declare void @llvm.dbg.value(metadata, metadata, metadata) #038 39 attributes #0 = { nocallback nofree nosync nounwind readnone speculatable willreturn }40 41 !llvm.module.flags = !{!0, !1}42 !llvm.dbg.cu = !{!2}43 44 !0 = !{i32 2, !"Debug Info Version", i32 3}45 !1 = !{i32 2, !"CodeView", i32 1}46 !2 = distinct !DICompileUnit(language: DW_LANG_C99, file: !3, isOptimized: false, runtimeVersion: 0, emissionKind: FullDebug)47 !3 = !DIFile(filename: "test", directory: ".")48 !4 = distinct !DISubprogram(name: "fn", linkageName: "test.fn", scope: !5, file: !5, line: 32, type: !6, scopeLine: 32, flags: DIFlagStaticMember, spFlags: DISPFlagLocalToUnit | DISPFlagDefinition, unit: !2, retainedNodes: !10)49 !5 = !DIFile(filename: "test.o", directory: ".")50 !6 = !DISubroutineType(types: !7)51 !7 = !{!8, !9}52 !8 = !DIBasicType(name: "bool", size: 1, encoding: DW_ATE_boolean)53 !9 = !DIBasicType(name: "f16", size: 16, encoding: DW_ATE_float)54 !10 = !{!11}55 !11 = !DILocalVariable(name: "x", arg: 1, scope: !12, file: !5, line: 32, type: !9)56 !12 = distinct !DILexicalBlock(scope: !4, file: !5, line: 32, column: 1)57 !13 = !DILocation(line: 32, column: 31, scope: !12)58 !14 = !DILocation(line: 33, column: 5, scope: !15)59 !15 = distinct !DILexicalBlock(scope: !12, file: !5)60...61---62name: test.fn63body: |64 bb.0:65 liveins: $b066 DBG_VALUE $b0, $noreg, !11, !DIExpression(), debug-location !1367 renamable $s0 = nofpexcept FCVTSHr killed renamable $h0, implicit $fpcr, debug-location !1468 DBG_VALUE $b0, $noreg, !11, !DIExpression(DW_OP_LLVM_entry_value, 1), debug-location !1369 nofpexcept FCMPSri killed renamable $s0, implicit-def $nzcv, implicit $fpcr, debug-location !1470 renamable $w0 = CSINCWr $wzr, $wzr, 0, implicit killed $nzcv, debug-location !1471 RET undef $lr, implicit killed $w072...73
