Function Documentation
◆ is_va_list_type()
Return true iff TYPE is stdarg va_list type (which early SRA and IPA-SRA should leave alone).
References is_va_list_type(), TYPE_MAIN_VARIANT, and va_list_type_node.
Referenced by is_va_list_type(), and maybe_add_sra_candidate().
◆ sra_get_max_scalarization_size()
| unsigned HOST_WIDE_INT sra_get_max_scalarization_size | ( | void | ) |
Get the total total scalarization size limit in the current function.

◆ sra_total_scalarization_would_copy_same_data_p()
Given two types in an assignment, return true either if any one cannot be totally scalarized or if they have padding (i.e. not copied bits)
References check_ts_and_push_padding_to_vec(), i, sra_padding_collecting::m_padding, and sra_total_scalarization_would_copy_same_data_p().

◆ type_internals_preclude_sra_p()
Scalar Replacement of Aggregates (SRA) converts some structure references into scalar references, exposing them to the scalar optimizers. Copyright (C) 2019-2026 Free Software Foundation, Inc.

Return true iff the type contains a field or an element which does not allow scalarization.
