/* On the sh4, the DRi pseudo registers are problematic if the target
is little endian. When the user writes one of those registers, for
- instance with 'ser var $dr0=1', we want the double to be stored
+ instance with 'set var $dr0=1', we want the double to be stored
like this:
- fr0 = 0x00 0x00 0x00 0x00 0x00 0xf0 0x3f
- fr1 = 0x00 0x00 0x00 0x00 0x00 0x00 0x00
+ fr0 = 0x00 0x00 0xf0 0x3f
+ fr1 = 0x00 0x00 0x00 0x00
This corresponds to little endian byte order & big endian word
order. However if we let gdb write the register w/o conversion, it
will write fr0 and fr1 this way:
- fr0 = 0x00 0x00 0x00 0x00 0x00 0x00 0x00
- fr1 = 0x00 0x00 0x00 0x00 0x00 0xf0 0x3f
+ fr0 = 0x00 0x00 0x00 0x00
+ fr1 = 0x00 0x00 0xf0 0x3f
because it will consider fr0 and fr1 as a single LE stretch of memory.
To achieve what we want we must force gdb to store things in
In case the target is big endian, there is no problem, the
raw bytes will look like:
- fr0 = 0x3f 0xf0 0x00 0x00 0x00 0x00 0x00
- fr1 = 0x00 0x00 0x00 0x00 0x00 0x00 0x00
+ fr0 = 0x3f 0xf0 0x00 0x00
+ fr1 = 0x00 0x00 0x00 0x00
The other pseudo registers (the FVs) also don't pose a problem
because they are stored as 4 individual FP elements. */
