Hi,
[set JUMP_TABLES_IN_TEXT_SECTION to 1]
I added tests that use linker relaxation and discovered a relaxation bug
in binutils 2.26 (and later) that messes up symbol values in the
presence of alignment directives. I'm working on that right now -
hopefully, it'll get backported to the release branch.
Once that gets upstream, I'll resend the patch - with more tests, and
incorporating your comments.
There were two binutils bugs (PR ld/20221 and ld/20254) that were
blocking this patch - on enabling, relaxation, jumptables were
getting corrupted. Both of the issues are now fixed, and the fixes
are in master and 2.26 branch.
Should we mention in the release notes that Binutils >= 2.26 is needed
for avr-gcc >= 6 ?
Maybe even check during configure whether an appropriate version of
Binutils is used?
