Hey,

The first build always takes up more than 10G of memory, seemingly at the time of linking

Can some optimization be done?

Thanks

Hello @kcrazy

I worried that this problem bothers you.
I wanted to observe this problem. So I continuously checked the memory usage
with two commands: watch free -g and htop.
I cleaned the target directory with cargo clean and then run cargo build --examples.

But I did not see the memory usage spike... In my machine, the used memory size
was 2g before the building procedure. And while running the command, the used
memory size was also 2~3g.

Since I could not see the memory consumption goes up to 10g, can you
elaborate your situation?

Thanks,

Hi @rsdy
Have you experienced this situation? If you have, can you explain what caused that?

Hello @rhdxmr

I use my own compilation of llvm 12.0.0
So my command line is

LLVM_SYS_120_PREFIX=$HOME/llvm RUST_BACKTRACE=full cargo build -v --examples

build

htop:
htop

processes with a lot of memory usage have a long command line,

and I replace the spaces on the command line with newlines:

@kcrazy

I tried to look into this problem.
Thanks to your description, today I investigated a bit more than 2 days ago.

I saw your screen shot of htop and I recognized that your ld programs consume
lots of memory. And their states are D, the uninterruptible sleep state. I
guess the D states are incurred by heavy read/write of swap disk because RAM is
insufficient. So now perhaps you are suffering from bad compilation
performance.

Anyway, I tried to witness heavy memory consumption with my machine but I
failed.

I launched htop: htop -d 10. With the -d option, it refreshes stats every 1
second. And then, I hit F4 key to filter command lines with this keyword: liblto_plugin.so.
I found that ld program ran very shortly and exited. But it did not consume
that much memory you saw in your machine.

I monitored the exec system call with execsnoop:

sudo /usr/share/bcc/tools/execsnoop --max-args 1000 -l liblto_plugin.so 2>/dev/null | tee execsnoop.log

This command captures command lines that contain liblto_plugin.so as their
argument.

And I found this, but it is a bit different with yours. As you pasted, I also
replaced white-spaces with newlines for convenience. Note that the max length
of each argument is 128 bytes. Hence, too long arguments are cut. It is the limit
of execsnoop command.

Most arguments are the same with your command line. But I found that your
command line include more rlibs than mine. You can see the list of rlibs
after the -Bstatic option. rlib files are archives of ELF object files for
static linking. I guess, the more archives the more memory consumption.

These are the extra libraries of your command line, compared to mine:

libarrayvec
libbyteorder
libbytes
libcombine
libfutures
libfutures_channel
libfutures_core
libfutures_executor
libfutures_io
libfutures_sink
libfutures_task
libfutures_util
libgoblin
libhexdump
libitertools
liblinked_hash_map
libllvm_sys
libmio
libpin_utils
libplain
libredbpf
libscroll
libsignal_hook_registry
libslab
libtime
libtokio
libtoml_edit

You can see it using cargo tree command.

Can you check that the size of the extra libraries such as libllvm_sys? Are
they big?

Hello @kcrazy
How is it going there?
It's been a while since I responded the last reply.

I wonder you found a solution.
Thanks,

Hello @rhdxmr
I'm very sorry, I'm busy with some other things these days.
Now I'm back to focusing on this issue.

As you said, I found that the libllvm_sys file size is very large:

$ find .|grep libllvm_sys | xargs ls -lh

Hello @kcrazy

LLVM_SYS_120_PREFIX=$HOME/llvm RUST_BACKTRACE=full cargo build -v --examples

I saw you used custom LLVM 12 in your home directory.
How did you install that?
I'd like to install the custom LLVM 12 in my machine and reproduce the issue.

Hello @rhdxmr

Download and unpack a copy of the source for the llvm 12.0 version.

mkdir -p llvm/build
cd llvm/build
cmake .. -DCMAKE_INSTALL_PREFIX=$HOME/llvm

I referenced this page:
https://github.com/tari/llvm-sys.rs

@kcrazy

I followed the instruction you gave to me and referenced the page you mentioned and I successfully installed custom LLVM 12.

Using the custom LLVM 12, I reproduced the problem that ld processes consume too much memory.
Look at this screenshot. You can see that 3 ld processes use over 20G in my machine. Wow.

htop

Here's my solution to reduce the memory consumption.
When you build your custom LLVM12, make it as a Release.

$ tar -xaf llvm-12.0.0.src.tar.xz
$ mkdir -p llvm-12.0.0.src/build
$ cd llvm-12.0.0.src/build
$ cmake .. -DCMAKE_INSTALL_PREFIX=$HOME/llvm-12-release -DCMAKE_BUILD_TYPE=Release
$ cmake --build . --target install

As you can see, -DCMAKE_BUILD_TYPE=Release solves the problem.

$ LLVM_SYS_120_PREFIX=$HOME/llvm-12-release/ cargo build -v --examples

How about trying this?

I mentioned this issue at the tutorial to guide new users how to build LLVM from source.
See #217 for more information.
