== String routines ==

* After some discussions about IT semantics managed to shave a couple of instructions out of a couple of routines  * Got around to trying a suggestion that was made some months ago, that LDM is faster than LDRD on A9's; and indeed it does seem to be in some cases; those cases seem pretty hard to define though - it's no slower than LDRD, so it seems best to avoid LDRD.  * Digging around eglibc's build/configure system to see how to add assembler routines to only get used on certain build conditions (i.e. v7 & up)

EGLIBC uses a crazy-long directory tree to pick the most specific version. Pass --enable-debug-configure to configure and it will dump them out. I think --with-cpu=cortex-a8 adds to that path.

== SPEC ==

* Compiled lbm -O2 and ran it on our local panda and on Michael's ursa1 - it seems happy (with a drop of swap); so I'd say that confirms the issues I previously had were local to something on canis.  That's a bit of a pain since it's the only machine with enough RAM to run the rest of the suite.

== Other ==

* Tested a headless Alpha-2 install on our Beagle C4 - mostly worked  * Tested qemu-linaro release on the realview-pbx kernel/nfs setup I had  * A simple smoke test for pldw on qemu  * Tripped over ltrace not working while trying to profile git's use of memcpy and memcmp; it does some _very_ odd things; it's predominant size of memcpy seems to be 1 byte.

Is this with the patches that Zach sent upstream but haven't yet been merged?
