This revision is now accepted and ready to land.

Sounds reasonable. I'm sure x86_64 is in at least as good as shape as i386.

[Adrian McCarthy via Phabricator via lldb-commits]

amccarth added a comment.

I'm in no position to evaluate the functionality of lldb on Windows.  I've 
spent the last few months trying to understand why 900+ tests spontaneously 
started failing on Windows.

Fixed the typo, labeling the AArch64 support experimental too.

Sure, I can label the AArch64 bit experimental too.

I wouldn't include comments about python here though. The fact that it's not 
easy to build LLDB with python for windows/aarch64 isn't an intrinsic feature 
of LLDB or something that is missing in LLDB, that's just python.

It is actually possible to cross compile LLDB with python support for 
windows/aarch64, at least for the mingw target. Python itself is a bit tricky 
to cross compile, but once that cross compilation itself works, building it for 
windows/aarch64 isn't any worse than for x86. In 
https://github.com/mstorsjo/llvm-mingw/issues/73 there's ongoing efforts in 
building and packaging LLDB for windows with python enabled. As it's primarily 
cross compiled, it's a bit tricky for running tests though.

IMO, the biggest hurdle right now is swig/API generation and python support
enablement. If you think that is working already with some hack, then please
share it with me. I am using MS Surface Arm64 for the build.


Hi,

I never ran the full testsuite, and I built with python disabled.

I did manage to run some testcases, but I'm cross compiling (building on 
x86_64 linux, targeting aarch64 windows), so I transplanted parts of the 
testsuite to the target system and ran it via WSL - not very smooth, but 
it helped create and verify some test cases like 
test/Shell/Register/aarch64-fp-read.test at least.

HI  mstorsjo, did you manage to run LLDB testsuite with python support
enabled on windows. Can you please share steps to build and test LLDB on
windows on Arm/AArch64 if you have them handy somewhere. I ll check if
there is something missing on our part which needs to be done to get LLDB
in reasonable shape on windows on Arm/AArch64.

IMO, the biggest hurdle right now is swig/API generation and python support
enablement. If you think that is working already with some hack, then
please share it with me. I am using MS Surface Arm64 for the build.

Yes, I implemented support for both ARM and AArch64 in late 2019.

Possibly yes. I was referring to an issue for the ARM part that I never got 
time to fix properly, see D70840 . Other than 
that, I don't know of any issues with the AArch64 part, but I haven't used it 
very much either, fwiw.

Do we support 32 bit Arm specifically? (I'm not very familiar with Windows 
targets)

@omjavaid Has done some testing on the latest Windows On Arm which is AArch64. 
I think you should probably say "ARM and AArch64 support is more" but he can 
comment on how well it works.

[Martin Storsjö via Phabricator via lldb-commits]

mstorsjo created this revision.
mstorsjo added reviewers: labath, amccarth.
Herald added subscribers: pengfei, arphaman, kristof.beyls.
mstorsjo requested review of this revision.
Herald added a project: LLDB.

It was pointed out to me that the docs previously only said i386 was supported, 
while I'd expect that at least x86_64 is on the same level, and AArch64 should 
work pretty well for basic things at least.
