Richard Henderson 043d65862a tcg/aarch64: Fix constant subtraction in tcg_out_addsub2 ... An hppa guest executing 0x000000000000e05c: ldil L%10000,r4 0x000000000000e060: ldo 0(r4),r4 0x000000000000e064: sub r3,r4,sp produces ---- 000000000000e064 000000000000e068 sub2_i32 tmp0,tmp4,r3,$0x1,$0x10000,$0x0 after folding and constant propagation. Then we hit tcg-target.c.inc:640: tcg_out_insn_3401: Assertion `aimm <= 0xfff' failed. because aimm is in fact -16, but unsigned. The ((bl < 0) ^ sub) condition which negates bl is incorrect and will always lead to this abort. If the constant is positive, sub will make it negative; if the constant is negative, sub will keep it negative. Backports 707b45a2475e25709f0dee00f8fdf39d346ed21e		2021-03-09 13:16:41 -05:00
