The regression reported in PR optimization/7675 showed up
starting with this patch:
2000-11-11 Jason Merrill <jason@redhat.com>
* function.c (assign_parms): If TREE_ADDRESSABLE is set, try to
give the parm a register and then call put_var_into_stack.
* stmt.c (expand_decl): Likewise.
cp/
* typeck.c (mark_addressable): Don't call put_var_into_stack.
Here's a small test case that causes the compiler to ICE
when compiled on i686-linux with -O:
-------------------
/* ICE when compiled with -O */
int dummy (int *);
void foo(int i, int j)
{
int k=j;
void bar() { int x=k, y=i, z=j; }
dummy(&j);
}
-------------------
Output from the mainline compiler:
7675.c: In function `foo':
7675.c:9: internal compiler error: in fixup_var_refs_1, at function.c:1900
