Aurelien Jarno e750591c8a tcg/mips: fix add2 The add2 code in the tcg_out_addsub2 function doesn't take into account the case where rl == al == bl. In that case we can't compute the carry after the addition. As it corresponds to a multiplication by 2, the carry bit is the bit 31. While this is a corner case, this prevents x86-64 guests to boot on a MIPS host.

Aurelien Jarno e750591c8a tcg/mips: fix add2

The add2 code in the tcg_out_addsub2 function doesn't take into account
the case where rl == al == bl. In that case we can't compute the carry
after the addition. As it corresponds to a multiplication by 2, the
carry bit is the bit 31.

While this is a corner case, this prevents x86-64 guests to boot on a
MIPS host.
