For purposes of dynamically calling code, I need the following layout
of the assembled code:
0x00: 16-byte header
0x10: entry point #1
0x20: entry point #2
I want to use the new align/skip instructions for this. My code
generator currently looks like this:
align (16)
header:
skip (16)
entry1:
jump label1
align (16)
entry2:
...
label1:
jump entry2 ; or some other code
However, with setup, GNU lightning often "optimizes" the block order
so that entry1 is no longer at the correct offset. How can I reliably
prohibit this? Putting skip (1) after the second align (16) seems to
help in my experiments.
Thanks,
Marc

Happy new year. But this topic does not fit bug-gnulib. Maybe you sent it
to the wrong list?

Happy new year, Bruno!
Yes, sorry, wrong list! :)
