== Progress ==

* TCWG-1155 - Move ASAN 39bit bot to GlobalISel [1/10]
- Moved to the public silent master, ready for the final move on
Monday if it's stable until then

* TCWG-1172 - [ARM GlobalISel] Support G_FCMP [5/10]
- Most of the functionality is implemented, but I intend to do a lot
of refactoring before committing

- Committed upstream

* Misc [3/10]
- Mailing lists, buildbots, discussions

== Plan ==

* Wrap up TCWG-1172
* More GlobalISel
* More code reviews

[Peter Smith]

== Activity ==
- Rebased and posted for review all my range-thunks work for LLD as
there had been some interest from some individuals on IRC in trying
out the patch.
-- Seems to work for them
-- Hoped that this might provoke upstream into looking and reviewing
the patches but no such luck.
- Landed the patch that sets _GLOBAL_OFFSET_TABLE_ so that FreeBSD can
link on ARM
- Some other small lld patches
- Investigations into whether an X86 patch might affect CFI generation
for AArch64.

Spent some time banging my head against the compiler-rt build system
to try and see if I can get a cross-compiled build and test run on
Qemu when my compiler-rt target != the default target (i.e. I want to
build clang with ARM and AArch64 targets and cross-build and test all
the ARM compiler-rt targets from that)
- Thwarted by what seems to be inconsistent decisions about
auto-detection of options, what is an architecture, target, sub-target
and abi.
- By passing in all auto-generated options by steam I'm still hitting
some problems with some tests that have an external assembly file.

Found numerous other small inconsistencies that I'll need to write up.

== Plans ==
- Ping the Range Thunks reviews again.
- Compiler-rt
Aim to get to the point where I can write a coherent mail to llvm-dev
explaining what I think is wrong and what I think needs changing.
