struct ModuleInfoHeader

Declaration

struct ModuleInfoHeader { /* full declaration omitted */ };

Description

The header preceding each entry in the Module Info substream of the DBI stream. Corresponds to the type MODI in the reference implementation.

Declared at: llvm/include/llvm/DebugInfo/PDB/Native/RawTypes.h:212

Member Variables

public support::ulittle32_t Mod

Currently opened module. This field is a pointer in the reference implementation, but that won't work on 64-bit systems, and anyway it doesn't make sense to read a pointer from a file. For now it is unused, so just ignore it.

public llvm::pdb::SectionContrib SC

First section contribution of this module.

public support::ulittle16_t Flags

See ModInfoFlags definition.

public support::ulittle16_t ModDiStream

Stream Number of module debug info

public support::ulittle32_t SymBytes

Size of local symbol debug info in above stream

public support::ulittle32_t C11Bytes

Size of C11 line number info in above stream

public support::ulittle32_t C13Bytes

Size of C13 line number info in above stream

public support::ulittle16_t NumFiles

Number of files contributing to this module

public char[2] Padding1

Padding so the next field is 4-byte aligned.

public support::ulittle32_t FileNameOffs

Array of [0..NumFiles) DBI name buffer offsets. In the reference implementation this field is a pointer. But since you can't portably serialize a pointer, on 64-bit platforms they copy all the values except this one into the 32-bit version of the struct and use that for serialization. Regardless, this field is unused, it is only there to store a pointer that can be accessed at runtime.

public support::ulittle32_t SrcFileNameNI

Name Index for src file name

public support::ulittle32_t PdbFilePathNI

Name Index for path to compiler PDB
