Thus we build with C only and the target doesn't have any need for SJLJ information. Unfortunately libgcc always probes for this. checking whether decimal floating point is supported... no configure: WARNING: decimal float is not supported for this target, ignored checking whether fixed-point is supported... no checking whether to use setjmp/longjmp exceptions... unknown configure: error: unable to detect exception model And if you pass in --disable-sjlj-exceptions, the build fails in libgcc with an ICE. ^ permalink raw reply [flat|nested] 4+ messages in thread

What is the contents of the failing config.log? Hmm... then this should work. We intentionally don't deviate much from *-elf targets. I was only building C in this run. > Also, there's nothing m32c-specific in the sjlj checks, it's the same for > all sjlj targets. I know. But m32c and (I think) h8300 were the only failures. ^ permalink raw reply [flat|nested] 4+ messages in thread
