- changing the parameter to an 'int' (as done below,
- for PCC on most machines), is the right thing to do
- on all machines, but I don't want to risk breaking
- something that already works. On most PCC machines,
- the sparc problem doesn't come up because the calling
- function has to zero the top bytes (not knowing
- whether the called function wants an int or a short),
- so there is little practical difference between an
- int and a short (except perhaps what happens when the
- GDB user types "print short_arg = 0x10000;").
-
- Hacked for SunOS 4.1 by gnu@cygnus.com. In 4.1, the
- compiler actually produces the correct address (we
- don't need to fix it up). I made this code adapt so
- that it will offset the symbol if it was pointing at
- an int-aligned location and not otherwise. This way
- you can use the same gdb for 4.0.x and 4.1 systems.
-
- If the parameter is shorter than an int, and is
- integral (e.g. char, short, or unsigned equivalent),
- and is claimed to be passed on an integer boundary,
- don't believe it! Offset the parameter's address to
- the tail-end of that integer. */
