I somewhat suspect this hunk of code in c-typeck.c:build_component_ref:
if (TREE_THIS_VOLATILE (datum) || TREE_THIS_VOLATILE (subdatum))
TREE_THIS_VOLATILE (ref) = 1;
I don't see anything that sets TREE_SIDE_EFFECTS.
However, from tree.h:
If this bit is set in an expression, so is TREE_SIDE_EFFECTS. */
#define TREE_THIS_VOLATILE(NODE) ((NODE)->common.volatile_flag)
However, I'm having a hard time getting good connectivity back to my build
machine to experiment with this.
Joseph, any ideas about this?
