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.
