gcc - C tail call optimization for boolean AND -

Does GCC perform tail call optimization on the following function?

  bool isEqual (node ​​* Head1, node * head 2) {if (head1 == weaken = head 2 == faucet) return head 1 == tap & amp; Head2 == faucet; Return Head 1- & gt; Data == Head 2- & gt; Data & amp; Amp; IsEqual (head1-> Next, head2-> Next); }  

Yes, at least this is the way I compiled it. RDI, RDI Sete DL Test RSI, RSI Set CL mov eax, ECX or AL, DL jne .L2 MOV: assembly code for that function

  isEqual (node ​​*, node *) was EDX , DWORD PTR [RSI + 8] CMP DWORD PTR [RDI + 8], EDX JE .L5 Representative retired .L2: mov eax, ECX and eax retired EDX .5: mov RDI, QWORD PTR [RDI] mov RSI, QWORD PTR [RSI] testing RDI, RDI Sette DL test RSI, RSI Sette CL mov eax, ECX or AL, DL jne .L2 mov ECX, DWORD PTR [RSI + 8] CMP DW ORD PTR [RDI + 8], ECX JE L5 representative retired  

This is the reason that there is clearly a loop, and no nested calls appear.

You should verify whether this is your compilation option with your version of GCC as well as on your platform.
