0x1f, in all of the functions.

+    tcg_gen_add_tl(mask, mask, ctx->one);
+    tcg_gen_shr_tl(mask, ctx->one, mask);
+    tcg_gen_sub_tl(mask, mask, ctx->one);

I know this is the description in the manual, but this will produce a shift of 32 with an input of 31, which is illegal in tcg.

You need to use

  mask = -1u >> (src2 ^ 31)
