Hi,
MIPS does not currently implement a mips_delegitimize_address target hook and
for n64, a RTL is produced which the standard delegitimize cannot handle:
(const:DI (plus:DI (unspec:DI [
(symbol_ref:DI ("s") )
] 229)

Hi,
The Octeon pop instruction does not take into account the upper 32bits of the
64bit register, so its usage can be optimized when there is a truncation right
before the instruction.
This patch implements this small optimization.
OK? Bootstrapped and tested on MIPS64-linux-gnu (Octeon) wit
Hi,
Currently doing a 32bit unaligned load on MIPS64, produces 4 byte loads, this
can be improved to using lwl/lwr instead. The problem is the code in
mips_expand_ext_as_unaligned_load that handles this case does handle the case
where the register is DImode but the width is 32.
