+Subject: [PATCH 1/2] nir: Fix cast
+
+We were wrongly telling `nir_const_value_as_uint()` that `iter` had
+`bit_size` bits, but in one case it is explicitly i64. This works on
+little endian platforms, but caused the nir_loop_unroll_test.fadd{,_rev}
+tests to fail on big endian platforms.
+
+Bug: https://bugs.gentoo.org/921297
+Fixes: 268ad47c111 ("nir/loop_analyze: Handle bit sizes correctly in calculate_iterations")
