I think it's most important that we do this for the first arg, since CPython won't end up increffing it either.

Looked at all places it comes from and this looks safe (it's alive at least as long as the other arguments). We are now crashing on cpython_oldstyle_getattr_crash (a CPython crasher) but that's not really the fault of this change.

this is an advantage for _PyObject_GC_TRACK which before compiled to something like this: cmpq $-2, -16(%rdi) jne .LBB0_2 movq $-3, -16(%rdi) movq _PyGC_generation0(%rip), %rax movq %rax, -32(%rdi) movq _PyGC_generation0(%rip), %rax movq 8(%rax), %rax movq %rax, -24(%rdi) leaq -32(%rdi), %rcx movq %rcx, (%rax) movq _PyGC_generation0(%rip), %rax movq %rcx, 8(%rax) and now compiles to cmpq $-2, -16(%rdi) jne .LBB0_2 movq $-3, -16(%rdi) movq _PyGC_generation0(%rip), %rax movq %rax, -32(%rdi) movq 8(%rax), %rcx movq %rcx, -24(%rdi) leaq -32(%rdi), %rdx movq %rdx, (%rcx) movq %rdx, 8(%rax) notice that it had to load _PyGC_generation0 three times because the compiler had to assume that because of aliasing it got motified. (and this loads actually showed up in profiling as somewhat expensive)

I did not trigger this bug (also could not come up with a test) but just by inspecting the code I thought it's very suspicious. But I did remove the assert(!exc_state.is_reraise) assert because it got hit in a legitimate case, (c++ exception got rethrowen in the llvm tier, cought in our c++ code and rethrowen because of api mismatch. With no python code in between.)

I don't know what the reason is, but it's tripping up cffi's test suite.

so that it can be used in more places. Looking at pyxl_bench2_10x, most of the calls to PyType_GenericAlloc are from the dict and list iterator classes, which don't use DEFAULT_CLASS_SIMPLE (or DEFAULT_CLASS) since they use the same C++ class with multiple Python classes. So by extracting out the core of that function, it's now usable by those other classes. Also convert some things to DEFAULT_CLASS_SIMPLE while we're at it.

Numpy was hitting this a lot I love optimizing things we haven't approached before. This small change improved numpy.test() performance by 20%.
