GCC for powerpc-unknown-nto-qnx6.5.0   
Hello,

It's me again and now I'm trying to build GCC for powerpc-unknown-nto-qnx6.5.0 using cross-compilation tools for linux-
x86 host. Compilation fails with message:

make[4]: Entering directory '/home/max/gcc/build/powerpc-unknown-nto-qnx6.5.0/pic/libgcc'

# multilibs.

OK, I've solved this problem, but I've got another one:

How to fix it?

Your binutils are too old. Build the trunk binutils for ppc.

Re: GCC for powerpc-unknown-nto-qnx6.5.0   
I've successfully built binutils and updated /opt/qnx650/host/linux/x86/usr/bin/ntoppc-as, but unfortunately, I've got 
same error. This is output from gcc with "--verbose" flag:

/opt/qnx650/host/linux/x86/usr/bin/ntoppc-as --gdwarf2 -v -I. -I. -I../.././gcc -I/home/max/gcc/gcc_4_6_branch/libgcc -I

Am I need to update other executables from binutils?

Did you reconfigure and rebuild against the updated binutils?

i.e. config/rs6000/ppc-asm.h has

#ifdef HAVE_GAS_CFI_DIRECTIVE
# define CFI_STARTPROC                  .cfi_startproc
# define CFI_ENDPROC                    .cfi_endproc
# define CFI_OFFSET(reg, off)           .cfi_offset reg, off
# define CFI_DEF_CFA_REGISTER(reg)      .cfi_def_cfa_register reg
# define CFI_RESTORE(reg)               .cfi_restore reg
#else
# define CFI_STARTPROC
# define CFI_ENDPROC
# define CFI_OFFSET(reg, off)
# define CFI_DEF_CFA_REGISTER(reg)
# define CFI_RESTORE(reg)
#endif

and HAVE_HAS_CFI_DIRECTIVE will be defined by configure. The binutils 
2.25 that you just build should support the .cfi directives.

Yes, I've reconfigured and rebuilt gcc.
