Subject: Targets with non-byte-addressable memory
Date: Fri, 23 Sep 2005 08:59:00 -0000	[thread overview]
Message-ID: <dh0fuj$2nu$1@sea.gmane.org> (raw)


Hello!

Does anybody has experience of porting gdb to a target where memory is not
byte-addressable. That is, if you read 0x80000007 you get 4 bytes and if
you read 0x80000008 you get another 4 bytes.

The source has TARGET_CHAR_BIT macro, but no target under "config" makes use
of them which makes me suspect that setting it won't do any good. In fact,
after setting it to 32, I get compile error in ax-gdb.c:

        case 8 / TARGET_CHAR_BIT:
          ax_simple (ax, aop_ref8);
          break;
        case 16 / TARGET_CHAR_BIT:
          ax_simple (ax, aop_ref16);
          break;
        case 32 / TARGET_CHAR_BIT:
          ax_simple (ax, aop_ref32);
          break;
        case 64 / TARGET_CHAR_BIT:
          ax_simple (ax, aop_ref64);

as both 8/32 and 16/32 give 0, and I get duplicate case label.

So, any easy way for me?
