            Bug ID: 70364
           Summary: gcc.target/i386/cleanup-[12].c don't align stack
                    properly
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: hjl.tools at gmail dot com
  Target Milestone: ---

gcc.target/i386/cleanup-[12].c has

       ".subsection 1\n\t"
        ".type  _L_mutex_lock_%=, @function\n"
"_L_mutex_lock_%=:\n"
"1:\t"  "leaq   %1, %%rdi\n"
"2:\t"  "subq   $128, %%rsp\n"
"3:\t"  "call   bar\n"
"4:\t"  "addq   $128, %%rsp\n"
"5:\t"  "jmp    24f\n"
"6:\t"  ".size _L_mutex_lock_%=, .-_L_mutex_lock_%=\n\t"

It doesn't align stack to 16-byte boundary when calling bar.
