> VisionFive 2

It's a good solid reliable board, but over three years old at this point (in a fast-moving industry) and the maximum 8 GB RAM is quite challenging for some builds.

Binutils is fine, but on recent versions of gcc it wants to link four binaries at the same time, with each link using 4 GB RAM. I've found this fails on my 16 GB P550 Megrez with swap disabled, but works quickly and uses maybe 50 or 100 MB of swap if I enable it.

On the VisionFive 2 you'd need to use `-j1` (or `-j2` with swap enabled) which will nearly double or quadruple the build time.

Or use a better linker than `ld`.

At least the LLVM build system lets you set the number of parallel link jobs separately to the number of C/C++ jobs.

I see, I don't have a Megrez at my desk, only in the build system. I only have P550 as my "workhorse".

PS: I made a typo above - the P550 I was referring to was the SiFive "HiFive Premier P550". But based on your HN profile text, you must've guessed it as much :)
