In hindsight, that's obvious because __atomic_compare_exchange_8 requires -mv8plus, which AFAICS isn't enabled on 32-bit Linux/sparc and I found no way to do so. This is unlike 32-bit Solaris/SPARC, where TARGET_DEFAULT includes MASK_V8PLUS. While it's clear the Linux/sparc cannot move to the Solaris default since it still supports the V8 Leon CPUs, I wonder if it wouldn't be possible to allow for V8+ with --with-cpu=v9? There are other possible hacks, like explicitly passing -mv8plus for libgnat or linking with -latomic, but those would be just that: hacks. ^ permalink raw reply [flat|nested] 7+ messages in thread

As it happens, I still had the failed build tree around, so I just dropped in the patch and restarted the build. It completed successfully and the following make check-ada only found the expected failures. Thanks for the quick fix. ^ permalink raw reply [flat|nested] 7+ messages in thread
