From 1983b3e02952a26bf5e319e86bb95667bc420f06 Mon Sep 17 00:00:00 2001 From: David Malcolm Date: Thu, 25 Jan 2018 00:45:51 +0000 Subject: [PATCH] Fix jit.dg/test-alignment* (PR jit/82846) These testcases jit-compile functions that return char, but were erroneously calling them as if they returned int. This led to errors for certain target configurations (e.g. reading from %eax (32-bit) in the harness when only %al (8-bit) had been written to in the jit-compiled function). gcc/testsuite/ChangeLog: PR jit/82846 * jit.dg/test-alignment.c (create_aligned_code): Fix return type of "fn_type" typedef. * jit.dg/test-alignment.cc (verify_aligned_code): Likewise.
