Fwd: more gcc 4.7 backports?

[Joel Sherrill]

Hi

Does the RTEMS Community have interest in any gcc PRs that
have fixes for 4.8 being backported to 4.7?

If so, let me know so those requests are represented.

Thanks.

Last month I sent a list of bugreports that were 4.7 regressions, but had patches which fixed them for 4.8.  It looks like ~7 of these had been backported and 10 more bugreports now exist with potential for backporting as well.

Here are my rough notes:

backported:
44061 - diagnostic
54767 - wrong-code
55043 - rejects-valid
55107 - compile-time-hog
55660 - [lto] ice-on-invalid
55890 - ice-on-invalid

53844 - missed-optimization  (fixed back in July and waiting to see if any fallout?) - looks like it was backported, but then reverted?

some discussion on...
54073 - missed-optimization 'not planning to backport it right now.'
update: "I have moved this discussion to PR56309. Let's keep this PR open for eventual
backport of the patch in Comment #13 to 4.7 branch."


Not much activity on the remaining:

35634 - bad-code, however 'Unlikely going to be backported.'
43961 - [arm] target
48189 - ice-on-valid
48766 - ice-on-valid
51447 - wrong-code, however 'Could be back-ported, but IMHO this issue is not important enough for that so I'm not going to work on back-ports.'
53636 - wrong-code
53676 - missed-optimization (discussion about 4.7 backport after some more 4.8 exposure since August)
54051 - [arm] wrong-code?
54295 - wrong-code
54563 - ice-on-valid - already backported? ***
54919 - wrong-code, however 'no plans to work on back-ports of my patch for the release branches'
54974 - [arm] wrong-code (last comment was asking about 4.7 backport)
55018 - wrong-code
55614 - alignment issue/tree-optimization
55964 - ice


New bug reports with potential backports:
56077 - wrong-code "Fixed on trunk, needs to be ported to 4.6/4.7 mid-Match."
56403 - ice-on-valid "The fix seems extremely safe, so I think backporting to 4.6 and 4.7 makes sense."
56470 - ice-on-valid "Fixed on trunk.  Testing back-port to 4.7."
56608 - wrong-code - fixed on trunk 2013-03-13
56539 - wrong-code/ice-on-valid - fixed on trunk 2013-03-06 "The patch fixes the problem for both 4.7 and 4.8"
56270 - ice-on-valid - fixed on trunk 2013-03-05
56175 - missed-optimization - fixed on trunk 2013-02-25

new potential backports:
52448 - wrong-code - fixed on trunk 2013-02-08
48133 - ice-on-valid - fixed on trunk, but not clear where
45472 - ice (on-valid?) - fixed on trunk 2013-02-27

Hope this is useful.

thanks,
