--- Comment #1 from ktkachov at gcc dot gnu.org ---
This is just a failure to if-convert with -m32 due to costs.
The costing logic deems it to not be profitable, which may well be a valid
decision to make. In this case, if-converting would actually always be
profitable
as the code:
s64 d = a - b;
if (d == 0)
return a + c;
else
return b + d + c;
can be simplified to just "a + c" but that's not something we can see in ifcvt
(shouldn't the tree-level optimizers catch this earlier?).
I propose to skip the testcase for -m32, what is the standard way of specifying
that in the testsuite?
