Failing IR
When compiling the attached IR with llc, I get:
!dbg attachment points at wrong subprogram for function
!1 = distinct !DISubprogram(name: "main", linkageName:
"_ZN19backtrace_debuginfo4mainE", scope: !3, file: !2, line: 1, type: !4,
isLocal: true, isDefinition: true, scopeLine: 1, flags: DIFlagPrototyped,
isOptimized: true, templateParams: !5, variables: !5)
void ()* @foo
call void @bar(), !dbg !19
!19 = !DILocation(line: 1219, scope: !20, inlinedAt: !21)
!25 = distinct !DILexicalBlock(scope: !26, file: !2, line: 1, column: 10)
!26 = distinct !DISubprogram(name: "main", linkageName:
"_ZN19backtrace_debuginfo4mainE", scope: !3, file: !2, line: 1, type: !4,
isLocal: true, isDefinition: true, scopeLine: 1, flags: DIFlagPrototyped,
isOptimized: true, templateParams: !5, variables: !5)
LLVM ERROR: Broken function found, compilation aborted!
But when the target is changed to x86_64-unknown-linux-gnu the file compiles
successfully. I'm not 100% sure that we correctly emit debuginfo in the first
place (not my area of expertise), and this may also be related to r252219 but I
figured it was odd at least that it failed to compile with an MSVC target yet
successfully compiled for a Linux one!
