Re: [PATCH][RFC][wide-int] Fix some build errors on arm in wide-int branch and report ICE

[Kyrill Tkachov]

Ping.
http://gcc.gnu.org/ml/gcc-patches/2014-04/msg00769.html
Any ideas? I recall chatter on IRC that we want to merge wide-int into trunk 
soon. Bootstrap failure on arm would prevent that...

Thanks,
Kyrill

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:

Any ideas? The compiler was configured with: --enable-languages=c,c++,fortran 
--with-cpu=cortex-a15 --with-float=hard --with-mode=thumb
