Bug ID: 63682 Summary: m32c: libgcc configure checks for SJLJ model even when C++ and Java are disabled Product: gcc Version: 4.9.2 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libgcc Assignee: unassigned at gcc dot gnu.org Reporter: joel at gcc dot gnu.org On the m32c, C++ and Java are not supported. 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.
