Hi,
I've been playing with linux-linaro-tracking and the 2013.12 (and
2013.10, 2013.11) toolchain release and when turning on the NEON in
kernel option I get:
CC lib/raid6/neon4.o
lib/raid6/neon4.c: In function 'raid6_neon4_gen_syndrome_real':
lib/raid6/neon4.c:113:1: internal compiler error: in
dwarf2out_frame_debug_adjust_cfa, at dwarf2cfi.c:1078
}
^
Use the attached .txt as .config and do 'make zImage' to replicate the
problem. You will probably need to attached patch as well since some of
the linaro patches break namespace support :(
regards,

o TCWG-343 : Make LRA the default for the ARM backend (1/10)
- iWMMXT issue : back on the issue.
- Thumb1 issues : looked at bugzilla's reports.
o TCWG-345 : Analyse performance of LRA for ARM. (0/10)
- No progress this week.

* Misc. (1/10)
o Catching up with email, etc
o Meeting
== Next ==
* Still some time spend at university
* Continue the ongoing tasks.
* Branch merge reviews.
== Progress ==
* ARM Process Record:
- Follow up on patches, almost all patches accepted. [0.5/10]
- Got GDB committ rights and set up git for pushing patches. [0.5/10]
* Spent time to read through fortran functions prologue to find a new fix
for TCWG-267. [1/10]
* Initial investigation of handling breakpoint over fork [TCWG-177] [1/10]
* Getting documentation ready for Macau visa application [2/10]
== Plan ==
* Update and send patches where required and committ all approved patches.
* Work on breakpoints issues [TCWG-177] and reverse stepping through solib
issue [TCWG-315]
* Apply for Macau visa, given all documents get ready.
== Progress ==
* Libc probes support for Aarch64.
Posted patch for "libc" probes support to "__longjump". Worked on
review comments from Maintainers. Upstream discussions in progress.
Working on testing "glibc" by using --enable-systemtap.
* Experimented with "Cbuildv2" native building.
== Plan ==
- Continue Cbuildv2.
- Investigate "PGO" for Aarch64.
- Work on "glibc" probe.
== Issues ==
Waiting for feedback on "libssp" machine descriptions changes.
misc
===
14-Jan-2014 leave.
== Progress ==
* Draft wiki page (under ACL--let me know if you want to see) for
instructions for setting up chroots on chromebooks for glibc testing:
https://collaborate.linaro.org/display/~ryan.arnold@linaro.org/Configuring+…
* Investigated expanding remote testing possibilities in glibc.
* RFC email to libc-alpha discussing proposal for glibc host testsuite
in chroots:
https://sourceware.org/ml/libc-alpha/2014-01/msg00222.html
== Issues ==
* Shortened week (3-days) because of unplanned school closures on
Monday and Tuesday due to freezing temperatures, during which I had to
watch my kids.
== Plan ==
* Start code scaffolding for glibc host testsuite in chroot.
* Start cbuild2 scaffolding for building remote chroots for glibc testing.
* Add glibc multi-lib builds and IFUNC system libraries.
* Work on cbuild2 support for local tar files.
== Progress ==
* Two day week
* Catching up on email etc. after break (0.5/10)
* Investigate setjmp/longjmp SystemTap probe support in ARM glibc
(1/10, TCWG-378)
* Investigate toolchain bug reports for ARM and AArch64 (0.5/10)
== Issues ==
* None
== Plan ==
* Resume QEMU ARMv8 AArch32 work
* Hopefully push glibc ARM pointer encryption fix for 2.19
