* Out of office 1 day (public holiday)
* [GlobalISel] Better support for small types [LLVM-553]
- Fixed the bug that I'd been looking into
- Committed support for several instructions, only 3 left to commit next week
* IR SVE Reviews [LLVM-545]
- Looked into the patches for stack management
* GlobalISel code review
- Currently looking into an unpleasant patch adding a new opcode
* Catching up on Connect / EuroLLVM
== Plan ==
* More of the same
* Out of office end of May - beginning of June
[VIRT-327 # Richard's upstream QEMU work ]
Another round on launchpad 1824853, TB overflow.
This time handling relocation overflow. Which would
not be seen on an x86 host (2GB displacement), but
would affect some of the risc hosts.
Reviewed Peter's v7m fpu patches.
Another round on util/path.c, fixing the startup loop
that we get into for using a full chroot for -L.
Poked my nose into Alex's cputlb demacrofy patch set.
Hopefully the feedback was helpful...
First two pull requests for 4.1.

[PR40542] Sent patch for -n and -N support in LLD for upstream review
[LTO]
Investigated problems when using -Os -Oz with LTO, raised 2 PRs
- error if clang linker invocation uses -Os and -Oz
- strange error message when .bc used as a file extension for a
separate compile and link step
Crash in GNU ld when linking LLVM lto via the gold plugin. Looks like
a memory access/corruption problem in the conversion from .bc to bfd.
Other miscellaneous reviews for some linker script support in LLD.
Investigation into why ld.bfd with NOLOAD on the .gnu.build-id section
corrupts debug information.
== This Week ==
* PR88837 (7/10)
- Discussed and finalized algorithm for vector construction with Richard.
* GNU-606 (1/10)
- Experimented gdbserver memory consumption with docker.
* Public Holiday (2/10)
== Next Week ==
- Continue ongoing tasks.
== Progress ==
* Short week (Out of office 22 - 24 April)
* [GlobalISel] Better support for small types [LLVM-553]
- Investigated my bug some more, it doesn't seem to be related to my
recent patches but rather an existing issue which is exposed because
we select more functions now
- Might be related to LLVM-456 (Fix frame index sizes for i<32)
* Catching up on Connect / EuroLLVM
== Plan ==
* Try to confirm root cause of LLVM-553 issue
[VIRT-327 # Richard's upstream QEMU work ]
Fix TranslationBlock overflow, launchpad 1824853.
Investigated launchpad 1824768, i386 emulation on arm32.
But works-for-me.
A bunch of work on new gvec primitives. Primarily to
support David Hildebrand's target/s390 conversion, but
it does enable more vectorization in target/arm as well.

== Progress ==
* FDPIC
- Troubleshooting with stm32f469-disco. Trouble connecting via
cross-gdb over openocd. Updated GNU-411 and discussing with Omair.
Created GNU-606 to investigate if gdbserver memory consumption
increased since release 7.5.
* GCC upstream validation:
- little activity this week, close to e/o stage 4
* GCC
- ubsan on bare-metal toolchain: discussed with Peter, I will send an
email to llvm-dev list.
* Infra
- several boards crashed, increasing Jenkins build queue
- working on adding binutils regression testing to round-robin jobs
== Next ==
More of the on-going tasks
