[Qemu-devel] [PATCH] target/arm: Fix output of PAuth Auth

2019-06-09 Thread Richard Henderson
The ARM pseudocode installs the error_code into the original pointer, not the encrypted pointer. The difference applies within the 7 bits of pac data; the result should be the sign extension of bit 55. Add a testcase to that effect. Signed-off-by: Richard Henderson --- target/arm/pauth_helper.
