# 9a2a5f1b 22-Oct-2024 Dani Szebenyi <szedani@linux.ibm.com>

tcg/ppc: Fix tcg_out_rlw_rc

The TCG IR sequence:

mov_i32 tmp97,$0xc4240000 dead: 1 pref=0xffffffff
mov_i32 tmp98,$0x0 pref=0xffffffff
rotr_i32 tmp97,tmp97,tmp9

tcg/ppc: Fix tcg_out_rlw_rc

The TCG IR sequence:

mov_i32 tmp97,$0xc4240000 dead: 1 pref=0xffffffff
mov_i32 tmp98,$0x0 pref=0xffffffff
rotr_i32 tmp97,tmp97,tmp98 dead: 1 2 pref=0xffffffff

was translated to `slwi r15, r14, 0` instead of `slwi r14, r14, 0`
due to SH field overflow. SH field is 5 bits, and tcg_out_rlw is called
in some situations with `32-n`, when `n` is 0 it results in an overflow
to RA field.

This commit prevents overflow of that field and adds debug assertions
for the other fields

tcg/ppc: Use new registers for LQ destination

LQ has a constraint that RTp != RA, else SIGILL.
Therefore, force the destination of INDEX_op_qemu_*_ld128 to be a
new register pair, so that it cannot overlap the input address.

This requires new support in process_op_defs and tcg_reg_alloc_op.
