This fixes PR60761 by dumping decl context of function clones
as origin with <clone> appended instead of <built-in> that now
appears after we (compared to 4.8) clear DECL_LANG_SPECIFIC.
Thus for the testcase in PR60761 we now print
t.ii: In function 'void foo(int) <clone>':
t.ii:14:13: warning: iteration 3u invokes undefined behavior
[-Waggressive-loop-optimizations]
z[i] = i;
^
t.ii:13:3: note: containing loop
for (int i = 0; i < s; i++)
^
t.ii:14:8: warning: array subscript is above array bounds [-Warray-bounds]
z[i] = i;
^
instead of
t.ii: In function ‘<built-in>’:
t.ii:14:13: warning: iteration 3u invokes undefined behavior
[-Waggressive-loop-optimizations]
z[i] = i;
^
t.ii:13:3: note: containing loop
for (int i = 0; i < s; i++)
^
t.ii:14:8: warning: array subscript is above array bounds [-Warray-bounds]
z[i] = i;
^
or with 4.8
t.ii: In function ‘void _Z3fooi.constprop.0()’:
t.ii:14:8: warning: array subscript is above array bounds [-Warray-bounds]
z[i] = i;
^
IMHO an improvement over both variants.
Bootstrap and regtest running on x86_64-unknown-linux-gnu.
Honza - does ->former_clone_of apply recursively or do I have to
loop to find the "ultimate" clone-of? Jason, is <clone> good
or shall I use sth else (do we annotate in-charge vs. not in-charge
constructors specially for example?).
Ok?
Thanks,
Richard.
