rG2966d6e80b77: [MachOYAML] Allow handcrafting custom contents for DWARF sections.
Summary

This patch enables users to handcraft custom contents for DWARF
sections. If we specify the contents of DWARF sections both in the
'DWARF' entry and the 'content', yaml2obj will emit an error message.
In addition, this patch helps remove the restriction that only the
content of sections whose segname are __DWARF can be specified in the
"DWARF" entry.

Seems like removing this is unrelated to the patch description? Possibly it just means you need to add a comment to the description saying something like "this allows us to remove a limitation..."

Higuoxing updated this revision to Diff 289895.Sep 4 2020, 1:42 AM

Add a comment saying why we don't check the segname.

The comment is good, but I was actually referring to the patch description, which doesn't explain what we are actually allowing now here.

## Test that macho2yaml dumps the __debug_foo section (unrecognized debug section) ## Test that macho2yaml dumps the __debug_foo section (unrecognized debug section)
## as a raw content section. ## as a raw content section.
## Due to the current implementation of yaml2macho being buggy, we cannot generate a DWARF section
## where the sectname starts with '__debug_' and the segname is '__DWARF', from a raw content section.
## We've slightly modified the segname to be '__FOO'. macho2yaml will still treat it as a debug
## section.
