So what made the 1.82.0 and either 1.83.0 or 1.84.0 differ in size so=20 significantly? See below for my approach for the src tree. Hopefully you can do something similar or better for the build/tmp dir=20 that's a ~8 GB diff from 1.82 to 1.84. And still 7 GB after rm -rf src/gcc. Please read the rest of this email=20 and send the update if it's ready before spending time on the analysis of the size difference. > du -sh=C2=A0 poky/build/../1.8x.0/rustc-1.8x.0-src/ 9.8=20 > G=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0= =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0 12 G=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0= =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 12=20 > G=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0= =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0= =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 11 G > > The size of TMPDIR increased from 65 G in 1.82 to 73 G in 1.83 and=20 > remained same in 1.84. > After removing "src/gcc"(1.1 G) the size is reduced to 72G. > And the build and test worked well, I assume. If so please send the update with the rm -rf src/gcc . I took a look at the source tree differences a little. I tried using ncdu and meld but they aren't really the right tool.

Thanks Yash!

It's a bit odd that you see an 8G diff and YP AB saw 5 GB but that's close enough for now.

Please run the same analysis for 1.84 update both before and after removing the src/gcc .

Please summarize the data for 1.82, 1.83 and the two sets of data for 1.84.

I'd expect 1.84 + "rm -rf src/gcc" to be somewhat lar= ger than 1.82 but much smaller than 1.83.

TMDIR FS usage          =                &nb= sp;               =                     &n= bsp; v1.82.0            &nbs= p;             v1.83.0 =                    &n= bsp;     v1.84.0        &nbs= p;               &= nbsp; v1.84 + rm -rf src/gcc

What steps did you take (bitbake rust-native ? ) before comparing these tmp dir trees?

So what made the 1.82.0 and either 1.83.0 or 1.84.0 differ in size so significantly? See below for my approach for the src tree.<= br> Hopefully you can do something similar or better for the build/tmp dir that's a ~8 GB diff from 1.82 to 1.84.
And still 7 GB after rm -rf src/gcc. Please read the rest of this email and send the update if it's ready before
spending time on the analysis of the size difference.

du -sh  poky/build/../1.8x.0/rustc-1.8x.0-src/  &= nbsp;            9.8 G          =             &= nbsp;      12 G          &nbs= p;            = ;         12 G          &nbs= p;            = ;            =         11 G

The size of TMPDIR increased from 65 G in 1.82 to 73 G in 1.83 and remained same in 1.84.
After removing "src/gcc"(1.1 G) the size is reduced to = 72G.

And the build and test worked well, I assume.

If so please send the update with the rm -rf src/gcc .



I took a look at the source tree differences a little.
I tried using ncdu and meld but they aren't really the right tool.<= br>

I ended up doing the following:

Since I'm always asking for you to do the math, I got chatgtp to do mine for me:

Positive numbers indicate an increase in size, while the negative number for vendor indicates a decrease.

the major difference is the src dir.

+56	build_helper  
+56	rustc-std-workspace  
+4	rustdoc-json-types  =

+12	ci  
+60	bootstrap  <=

+88	librustdoc  =

+952	doc  
+403016	tools  <=
span>
+32	llvm-project  
+1105952	gcc  

Vendor dir is harder to compare since there are so many files and the num=
ber of files has changed:

=E2=9C=A6 =E2=9D=AF wc -l du/du-1.82-vendor du/du-1.84-vendor=20
  1511 du/du-1.82-vendor
  1530 du/du-1.84-vendor


The total size changed from 1975056 to 1926968 - a decrease, so that's no=
t worth looking into.

Thanks,

The main reason for FS usuage differences in v1.83 are:
1. Addition of gcc  ~1.1 G.2. The addition of enzyme AD sub module ~392 M=
b.
