I seem to remember some LTO related issues with the GC, because it makes it hard to track root pointers. This may be fixed though. You should search the github PR and Issue history for LTO

If this would be the case, it should throw in an "out of memory" error eventually, right?

Is this the wrong forum for this question?

I tried it and the setup was a little difficult first, because you need to invoke gcc with the -Wl option instead of calling the linker directly (which I didn't know). But I got it to work and it shaved another 3kB (~3%) off the binary (from 154kB with -Os to 151kB with -flto and -Os), might be usef...

Hey
I was wondering if enabling link time optimization would be useful for -Os or not at all?

Thanks, thats a shame though

Hi,
I was wondering if the firstbit option for the SPI module affects only tx or rx aswell (on the pyboard)?

Thanks!

Hey,

I know there are some C code formatting guidelines in the wiki. Did someone make a .clang file for that style?
Would be useful for running the auto formatter on VSCode.

Does nobody know?
