gcc-3.0/3.0.3 and gdb-5.1

gcc-3.0/3.0.3 and gdb-5.1

[Ish Rattan]

System is SunBlade-100, under Solaris-2.8.

gcc-2.95.2 (from Sunfreeware CD).

I compiled gcc-3.0 to 64-bit binary capable of generating 64-bit
binaries with /usr/ccs/as and /usr/ccs/bin/ld). It seems to work.
I tried to use gdb (with a binary generated with -g option) and it
did not work. So, I compled gdb-5.1 sources with 64-bit compiler
too. No success again. Partial gdb session is follows:

...
(gdb) b main
Cannot access memory at address 0x894
(gdb) run
Starting program: /local/home/ishwar/asm-new/a.out
Hello, world!!

Program exited normally.
(gdb) delete 1
No breakpoint number 1.
(gdb) b main
Cannot access memory at address 0x894
(gdb) b printf
Cannot access memory at address 0xffffffff7f28d2fc
(gdb) run
Starting program: /local/home/ishwar/asm-new/a.out
Hello, world!!

Program exited normally.

If the C-program is compiled without -g, the behavior is different.

...
This GDB was configured as "sparc-sun-solaris2.8"...

Looks like that gdb-5.1 does not have support for 64-bit version of
gcc-3.0?
