-frtl-abstract-sequences is known to be very broken.

Might be related to:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33642

Looks like the solution has been to disable those tests on a long list of
platforms. May be it's better to just remove -frtl-abstract-sequences from GCC
if it works nearly nowhere?

------- Comment #5 from jingyu at google dot com  2009-04-14 22:35 -------
I found that gcc.c-torture/compile/pr11832.c and pr33009.c were deleted from
gcc trunk on 2009-03-31.
2009-03-31  Ramana Radhakrishnan  <ramana.radhakrishnan@arm.com>
        * gcc.c-torture/compile/pr33009.c: Delete.
        * gcc.c-torture/compile/pr11832.c: Likewise.

However, these two files are still in gcc-4.4 branch (gcc version 4.4.0
20090414 (prerelease)).

Could someone delete these two files from gcc-4.4 branch?

Thanks!

-frtl-abstract-sequences was removed from the trunk so closing as won't fix.
