clayborg added inline comments.

Comment at: lldb/source/Plugins/SymbolFile/DWARF/DWARFDebugMacro.cpp:62
+ const DWARFDataExtractor &debug_str_offset_data,
const DWARFDataExtractor &debug_str_data, const bool offset_is_64_bit,
lldb::offset_t *offset, SymbolFileDWARF *sym_file_dwarf,
----------------
We could also remove "offset_is_64_bit" if we fix DataExtractor to handle it as
suggested below where "offset_is_64_bit" is used.
================
Comment at: lldb/source/Plugins/SymbolFile/DWARF/DWARFDebugMacro.cpp:128-131
if (offset_is_64_bit)
new_offset = debug_macro_data.GetU64(offset);
else
new_offset = debug_macro_data.GetU32(offset);
----------------
I have though about adding support to DataExtractor for extracting offsets.
Anyone that initializes a DataExtractor would need to set the offset size once,
and then everyone else could just call:
```
new_offset = debug_macro_data.GetOffset(offset);
```
We would need to add a field to DataExtractor:
```
Optional<uint32_t> m_offset_size; ///< The address size to use when
extracting offsets. Defaults to m_addr_size if this has no value
```
It would default to the m_addr_size if m_offset_size isn't set. The
"m_context.getOrLoadXXXX()" calls would then set the offset size correctly for
the current DWARF when it creates the DWARFDataExtractor.
================
Comment at: lldb/source/Plugins/SymbolFile/DWARF/DWARFDebugMacro.h:54-57
+ const lldb_private::DWARFDataExtractor &debug_macro_data,
+ const lldb_private::DWARFDataExtractor &debug_str_offset_data,
+ const lldb_private::DWARFDataExtractor &debug_str_data,
+ const bool offset_is_64_bit, lldb::offset_t *sect_offset,
----------------
To future proof this a bit should we pass in the "lldb_private::DWARFContext"
instead of the first three arguments?
================
Comment at: lldb/source/Plugins/SymbolFile/DWARF/SymbolFileDWARF.cpp:1056-1057
const DWARFDebugMacroHeader &header =
DWARFDebugMacroHeader::ParseHeader(debug_macro_data, offset);
DWARFDebugMacroEntry::ReadMacroEntries(
----------------
Move this into DWARFDebugMacroEntry::ReadMacroEntries() so that we don't have
to pass "header" as an argument?
