Hi all,
I have little confusion about machine modes.
Initially our architecture supports both 16 & 32 bit registers.
At that time we have used
QImode - char
HImode - intergers (16 bit)
SImode - long interger(32 bit)
Now we are proposed to change all registers to 32 bit registers.We have
corresponding load/store 8/16/32bit instructions available with
sign/zero extension.
Now any data item is represented as 32 bit value in registers.
Can I define a pattern with QImode / HImode/SImode (in .md file) or I
should use only SImode.
Thanks,
Siva Prasad
