Re: [v8-users] Large build size

2018-02-07 Thread 'Ali Sheikh' via v8-users 
I'm on a mac indeed. I tried a comparable build on my Linux machine:

➜  node git:(master) ls -l
./out/Release/obj.target/deps/v8/src/libv8_base.a ./out/Release/node
-rwxr-x--- 1 ofrobots eng 37422880 Feb  7 16:57 ./out/Release/node
-rw-r- 1 ofrobots eng  2533998 Feb  7 16:57
./out/Release/obj.target/deps/v8/src/libv8_base.a

Jakob, I'm glad to hear that your v8_base is only 29M for you. The .o files
in my obj/v8_base are large

1.1G obj/v8_base
Could this have something to do with libcpp_is_static?

Ali, are you on macintosh? Maybe this is only a problem on OSX. And I also
find that my resulting binaries are small-ish (150M) after linking in the
static v8 library - but my link step is quite slow as you would expect when
linking large binaries like that (~1 minute)

My local node `master` branch build (V8 6.4.388-40) does have a large
libv8_base.a, but the final binary is small. Maybe the compilers are
putting more stuff in there that the linker strips out.

❯ ls -l ./out/Release/libv8_base.a
-rw-r--r--  1 ofrobots  eng  1269949240 Feb  7 08:14

Re: [v8-users] Large build size

That does indeed seem very large. On Linux with a current checkout (and
without v8_static_library=true), my out/x64.release/obj/v8_base directory
with all the .o files is only 29MB.

Unfortunately, I have no idea what might be causing the difference in your
case. Do any *.o files stand out as very big? Have you tried deleting the
output directory (remember to save your args.gn first!) and compiling
everything from scratch? It's a blunt instrument but sometimes helps get
rid of old cruft...

[v8-users] Large build size

2018-02-07 Thread Ryan Dahl 
Hi,

I've noticed that the build size in the latest V8 releases is very large.

For example, on 6.5.257, I get

-rw-r--r--  1 rld  staff   1.1G Feb  7 18:49 out/v8build/obj//libv8_base.a

It's similarly large on 6.6.164. I'm experiencing this on OSX and here is 
the configuration I'm using:

is_component_build=false
is_debug=false
v8_deprecation_warnings=true
v8_enable_gdbjit=false
v8_enable_i18n_support=false
v8_experimental_extra_library_files=[]
v8_extra_library_files=[]
v8_imminent_deprecation_warnings=true
v8_static_library=true
v8_target_cpu="x64"
v8_untrusted_code_mitigations=false
v8_use_external_startup_data=false
v8_use_snapshot=false

Any suggestions on how to reduce the size? I'm surprised that the build 
size has gone from under 100M to over 1G in the span of a few years - is 
this a bug on my end or working as intended?


Thanks,
Ryan
