annotate libinterp/interp-core/jit-typeinfo.cc @ 15370:8355fddce815
Use sret and do not use save/restore stack (bug #37308)
* jit-typeinfo.cc (octave_jit_grab_matrix, octave_jit_cast_matrix_any,
octave_jit_paren_subsasgn_impl, octave_jit_paren_scalar_subsasgn,
octave_jit_paren_subsasgn_matrix_range): Return matrix directly.
(octave_jit_cast_range_any): Return range directly.
(jit_function::jit_function): Maybe mark llvm function return as sret.
(jit_function::call): Maybe mark llvm call sret and place allocas at function
entry.
(jit_function::do_return): Handle new parameter, verify.
(jit_typeinfo::jit_typeinfo): Match C++ std::complex type better, pass
jit_convetion::external explicitly, and disable right complex division.
(jit_typeinfo::create_identity): Improve name.
(jit_typeinfo::pack_complex, jit_typeinfo::unpack_complex): Handle changed
complex format.
* jit-typeinfo.h (jit_array::jit_array): New overload.
(jit_type::mark_sret, jit_type::mark_pointer_arg): Remove default convention.
(jit_function::do_return): Add verify parameter.
* pt-jit.cc (jit_convert_llvm::convert_function): Store the jit_function.
(jit_convert::visit): Call do_return if converting a function.
* pt-jit.h (jit_convert_llvm::creating): New member variable.
