Quoting Frank Isamov <frank.isa...@gmail.com>:
Hi,
I'd like to make a backend which would have 48 bits for 'long' type.
(32 for int and 64 for long long).
I have tried to define:
#define LONG_TYPE_SIZE 48
That's not a partial integer mode; PDImode would have the same size as DImode,
just not all bits would be significant.
and one of:
INT_MODE (PDI, 6);
And that wouldn't be PDImode, more like THImode (three-halves integer mode,
going by the precedent of TQFmode - three-quarter float mode - of the 1750a
port in GCC prior to version 3.1)
