https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86864 Richard Biener changed: What|Removed |Added CC||ebotcazou at gcc dot gnu.org --- Comment #3 from Richard Biener --- The issue looks like that (jump_insn 19 18 20 3 (parallel [ (set (pc) (reg:DI 94)) (use (label_ref 21)) ]) -1 (nil) -> 21) (barrier 20 19 21) doesn't have the jump at the end. Whoever inserted that barrier insn did it wrong. But I'm not too much of an expert here either.

--- Comment #2 from Martin Liška ---
It's strange because the CFG looks fine in optimized dump:
g (int b, int c, int d)
{
long int a.0_1;
[local count: 1073741825]:
if (b_5(D) > 0)
goto ; [50.00%]
else
goto ; [50.00%]
[local count: 1073741825]:
switch (b_5(D)) [75.00%], case 29: [25.00%], case 32:
[25.00%], case 40: [25.00%], case 42: [25.00%], case 48:
[25.00%]>
[count: 0]:
:
__builtin_unreachable ();
[local count: 1073312327]:
# c_2 = PHI <1(2), 2(3)>
:
if (d_6(D) != 0)
goto ; [33.00%]
else
goto ; [67.00%]
[local count: 719119259]:
a.0_1 = a;
if (a.0_1 != 0)
goto ; [50.00%]
else
goto ; [50.00%]
[local count: 713752697]:
f ();
[local count: 1073312326]:
if (c_2 == 1)
goto ; [20.24%]
else
goto ; [79.76%]
[local count: 217238415]:
f (); [tail call]
[local count: 1073312326]:
return;
I'm adding Jakub and Richi, they are more familiar with GIMPLE representation.
