From 0d51b6d87e3ad85b669fa11445fe71dbd6936e3d Mon Sep 17 00:00:00 2001 From: Daniel Hellstrom Date: Thu, 28 Jun 2018 14:39:37 +0200 Subject: capture: prevent unaligned access when reading time LLVM warns about this: cpukit/libmisc/capture/capture.c:405:30: warning: taking address of packed member 'time' of class or structure 'rtems_capture_record' may result in an unaligned pointer value [-Waddress-of-packed-member] rtems_capture_get_time (&in.time); And on sparc it generates an unaligned trap which makes smpcapture01 and smpcapture02 test to fail on sparc. --- cpukit/libmisc/capture/capture.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'cpukit/libmisc/capture/capture.c') diff --git a/cpukit/libmisc/capture/capture.c b/cpukit/libmisc/capture/capture.c index 19a90c5954..4d40b8f630 100644 --- a/cpukit/libmisc/capture/capture.c +++ b/cpukit/libmisc/capture/capture.c @@ -387,6 +387,7 @@ rtems_capture_record_open (rtems_tcb* tcb, if (ptr != NULL) { rtems_capture_record in; + rtems_capture_time time; ++cpu->count; @@ -402,7 +403,8 @@ rtems_capture_record_open (rtems_tcb* tcb, rtems_capture_task_real_priority (tcb) | (rtems_capture_task_curr_priority (tcb) << 8)); - rtems_capture_get_time (&in.time); + rtems_capture_get_time (&time); + in.time = time; /* need this since in is a packed struct */ ptr = rtems_capture_record_append(ptr, &in, sizeof(in)); } -- cgit v1.2.3
