Hi all (and wide-int maintainers in particular),
I tried bootstrapping the wide-int branch on arm-none-linux-gnueabihf and
encountered some syntax errors while building wide-int.h and wide-int.cc in
expressions that tried to cast to HOST_WIDE_INT. This patch fixes those errors.
Also, in c-ada-spec.c I think we intended to use the HOST_WIDE_INT_PRINT format
rather than HOST_LONG_FORMAT, since on arm-linux HOST_WIDE_INT is a 'long long'.
The attached patch allowed the build to proceed for me, but in stage 2 I
encountered an ICE:
$TOP/gcc/dwarf2out.c: In function 'long unsigned int
_ZL11size_of_dieP10die_struct.isra.209(vec<dw_attr_struct, va_gc>**, long

Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
See <http://gcc.gnu.org/bugs.html> for instructions.
Any ideas? The compiler was configured with: --enable-languages=c,c++,fortran
--with-cpu=cortex-a15 --with-float=hard --with-mode=thumb
Thanks,
Kyrill
