Hi Felix,

It looks like notes might be partly responsible:

> 01 .text

> 06 .eh_frame_hdr
Presumably you do not want these .note.gnu.property sections, or their
segments. (On the assumption that you do not mind if the loader does
not have access to the information in these notes).
I do not think that there is a command line option to prevent their
generation, (although it could be argued that there ought to be one).
Would it be possible for you to use a custom linker script ? One that
explicitly discards these note sections ?
The other difference I noticed is that there are now separate segments
for the .text section vs the .rodata/.eh_frame/.eh_frame_hdr sections.
This is a deliberate security enhancement as it allows the data segment
to marked as non-executable. But there is a linker command line option
to disable this feature: "-z noseparate-code".
I hope that this helps.
Cheers
Nick
