Marek,
Perhaps I didn't test the property test before as I did not realize there was a config to be enabled.
Enabling CONFIG_LTO breaks linking the SPL (linking uboot is fine): LTO spl/u-boot-spl make[2]: *** read jobs pipe: No such file or directory. Stop. make[2]: *** Waiting for unfinished jobs.... lto-wrapper: fatal error: make returned 2 exit status compilation terminated. /usr/src/venice/buildroot/output/host/lib/gcc/aarch64-buildroot-linux-gnu/9.3.0/../../../../aarch64-buildroot-linux-gnu/bin/ld: error: lto-wrapper failed collect2: error: ld returned 1 exit status scripts/Makefile.spl:461: recipe for target 'spl/u-boot-spl' failed make[1]: *** [spl/u-boot-spl] Error 1 Makefile:1985: recipe for target 'spl/u-boot-spl' failed make: *** [spl/u-boot-spl] Error 2
I'm using your lto branch
Best Regards,
Tim
Tim, try compiling with only one job, i.e. make -j1
If parallel build fails, we have a bug in the Makefile. It worked fine without the LTO patches.
The problem needs to be fixed before merging your series.
Best regards
Heinrich
