memcpy regression on A9 - TCWG-390 [7/10]
* Tweaked bench.py some more
* Cobbled together a bare metal version of cortex-strings benchmark
* Was surprised to find that the problem does not relate to Linux
* Have some evidence that points at the branch predictor
Meetings/mail/etc [3/10]
=Plan=
See if A9 performance is recoverable without sacrificing other targets
Push some of my improvements into the cortex-strings repo
Possibly write up my cortex-strings-benchmarking-in-lava method
Back to cbuild benchmark automation
== Progress ==
Zero/sign extension elimination (TCWG-291) 10/10
- Patch updated based on review comments.
- Regression tested with standard set-up
- Created test-cases.
- Set-up additional architectures for validation
* aarch64-none-elf --with-abi=ilp32 (Foundation model)
* aarch64-none-linux-gnu --with-abi=ilp32 seems to be broken.
* Set-up qemu based s390x-ibm-linux
* Tried x86_64-linux -mx32 but ran into many issues.
- Patch now waiting for s390x-ibm-linux. All others are OK.
- will post once the results are available
