[Bug bootstrap/30974] New: pdp11-dec-bsd will not successfully build

[hbent at cs dot oberlin dot edu]

I have an x86 NetBSD box and am attempting to build gcc for pdp11-dec-bsd.  I
have binutils 2.17 installed and configured for that target, and I have
includes and libraries from the latest revision of 2.11BSD.

configure is run as
../configure --target=pdp11-dec-bsd --enable-languages=c --with-gmp=/usr/pkg

Building gets to this point:

/usr/src/gcc/vax/./gcc/xgcc -B/usr/src/gcc/vax/./gcc/

The mis-generated assembly is at the very end of the file, and looks like this:

LC_0:
        0 /* short */
        0 /* short */
        0 /* short */
        0 /* short */
        .even
LC_1:
        0 /* short */
        0 /* short */

Unfortunately I have not the faintest clue as to what is happening here, or
why.  I would be happy to provide more details if someone can tell me what they
need.

static bool
pdp11_assemble_integer (rtx x, unsigned int size, int aligned_p)
{
  if (aligned_p)
    switch (size)
      {
      case 1:
        fprintf (asm_out_file, "\t.byte\t");
        output_addr_const_pdp11 (asm_out_file, x);
        fprintf (asm_out_file, " /* char */\n");
        return true;

      case 2:
        fprintf (asm_out_file, TARGET_UNIX_ASM ? "\t" : "\t.word\t");
        output_addr_const_pdp11 (asm_out_file, x);
        fprintf (asm_out_file, " /* short */\n");
        return true;
      }
  return default_assemble_integer (x, size, aligned_p);
}


TARGET_UNIX_ASM is true for pdp11-dec-bsd

Actually wait, you are using binutils but this target really defaults to the
old as and not binutils at all.

I'm not clear on what you're saying.  Is binutils not going to work at all for
this target?  It can't be built natively AFAIK, so I'm not sure what toolchain
I should be using if binutils isn't going to work.
