== Linaro GCC == * Reproduce regression of my ldm/stm backport on 4.5, which is caused by the other two merged patches in ifcvt.c. Fix them. Propose merge request again. Learn how to sync/merge changes from one branch to the other branch.

* Fix VFP_D0_D7 handling in predicate vfp_register_operand. Approved and committed upstreams.

* Test new regrename improvement patch on x86_64, and measure effectiveness of it on ARM. Code size of bash-3.2 is reduced 0.2% with option "-march=armv7a -mthumb -O2 -frename-registers". Eric B. is almost OK with this patch except some wording in comments.

== Linaro GDB == As discussed in UDS, I'll move to GDB work for gdb correctness. http://ex.seabright.co.nz/helpers/planner#tr-toolchain-gdb-correctness In this month, I'll focus on GDB testsuite failures fixing.

* Analyze LP:615978, failures in gdb.base/annota3.exp. Signal is not delivered to child while software single-stepping. The same as LP:649121.

* Fix failure in gdb.xml/tdesc-regs.exp. LP:685494 It is caused by a target triplet matching error, when target is set to "armv7l-linux-gnueabi". Target triplet matching in test cases should be changed. Patch is being reviewed in upstreams.

* LP:616000 failures caused by -fstack-protector. Homework to understand frame-related code in GDB. Got some big picture of usage of some key data structures inside GDB on frame. Compared with prologue with and without stack-protector, find some difference there. Still no clue on how to educate GDB to identify whether stack-protector is turned on or off.

* Fix one failure in printcmds.exp. LP:685702 This test case on 7.2 branch is a little bit out of date, compared with GDB trunk. Backport one patch on trunk to 7.2 branch can fix this problem. Backport patch is being reviewed in upstreams.

* Neon registers in kernel dump file. LP:615972 Ask Linaro kernel WG to see how to move forward on this. Discussion is still ongoing.

== This Week == * Report the rest of GDB testsuite failures. * Pick up some of them, and fix. * Pass gcc patches in my queue one by one to gcc-patches to review.
