Where's the optimiser gone? (part 5.c): missed tail calls, and more...
Compile the following functions with "-O3 -target i386-win32"
(see <https://godbolt.org/z/exmjWY>):
__int64 __fastcall div(__int64 foo, __int64 bar)
{
return foo / bar;
}
On the left the generated code; on the right the expected,
properly optimised code:
push dword ptr [esp + 16] |
push dword ptr [esp + 16] |
push dword ptr [esp + 16] |
