Bug ID: 41365
Summary: [codeview] Clang should use a better DISubprogram name
for dynamic initializer functions
Product: clang
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: LLVM Codegen
Assignee: [email protected]
Reporter: [email protected]

Otherwise the IDE will display the mangled name, which is silly.
Today, in VS, I see this stack frame:
> llvm-tblgen.exe!??__EMatchPrefix@@YAXXZ() Line 129 C++
Which is because we emit S_LPROC32_ID like this:
0 | S_LPROC32_ID [size = 56] `??__Ef@@YAXXZ`
parent = 0, end = 0, addr = 0000:0000, code size = 26
type = `0x1004 (??__Ef@@YAXXZ)`, debug start = 0, debug end = 0,
flags = none
Which is because we emit the DISubprogram like this:
!33 = distinct !DISubprogram(name: "??__Ef@@YAXXZ", scope: !3, file: !3, line:
12, type: !34, isLocal: true, isDefinition: true, scopeLine: 12, flags:
DIFlagPrototyped, isO
ptimized: false, unit: !2, retainedNodes: !4)
That "name:" field should be something human friendly instead of the mangled
name.
