Yes the testcase attached in the PR works for me but I can't change the
status because I am not the reporter (nor admin).
I will close it.
However, the testcase I have added g++.dg/tm/ctor-used.C fails. I can
fill another PR but I found this problem thanks to the PR testcase.
If you mean the following test, there is no ICE here either with current
sources. However, I do see that you expect something else to be generated.
If I compile it with optimization (-O1), there is no call to the runtime
as expected (no _ITM_getTMCloneOrIrrevocable), we just inline the
initialization to 0 inside the transaction. And we optimize away the
constructor "C():l(0)".
If I compile with no optimization, there is a the call through the
runtime (which according to your test you DONT expect, why?), and we
generate code for C():l(0). This seems correct.
I don't see anything wrong with the generated code.
What are you expecting?
+/* { dg-do compile } */
+/* { dg-options "-fgnu-tm -fdump-tree-optimized" } */
+
+struct C {
+ long l;
+ C():l(0) {}
+};
+
+int main()
+{
+ C* alloc;
+ __transaction_atomic {
+ alloc = new C;
+ }
+ alloc->l = 2;
+
+ return 0;
+}
+/* { dg-final { scan-assembler-not "_ITM_getTMCloneOrIrrevocable" } } */
+/* { dg-final { scan-tree-dump-times ";; Function C::C" 1 "optimized" }
} */
+/* { dg-final { cleanup-tree-dump "optimized" } } */
