[PULL 22/31] configs/targets: Forbid OpenRISC to use legacy native endianness APIs

Posted by Philippe Mathieu-Daudé 3 days, 1 hour ago

All OpenRISC-related binaries are buildable without a single
use of the legacy "native endian" API. Set the transitional
TARGET_NOT_USING_LEGACY_NATIVE_ENDIAN_API definition to forbid
further uses of the legacy API.

Preliminary commits allowing this final change:

 . 52392f95e69 target/openrisc: Inline translator_ldl()
 . 16c0efb5a7a target/openrisc: Use explicit big-endian LD/ST API
 . 5b67dbf1dc3 target/openrisc: Replace target_ulong -> uint32_t
 . 500708331e3 target/openrisc: Inline tcg_gen_trunc_i64_tl()
 . 4f6c60683f2 target/openrisc: Replace MO_TE -> MO_BE
 . 73cd283e58d target/openrisc: Introduce mo_endian() helper
 . 2f737e19a4d target/openrisc: Conceal MO_TE within do_store()
 . 22c36c0a20c target/openrisc: Conceal MO_TE within do_load()
 . ef797ac0025 target/openrisc: Explode MO_TExx -> MO_TE | MO_xx
 . 81e2fb236b7 target/openrisc: Remove 'TARGET_LONG_BITS != 32' dead code
 . 9dc4862dc4a target/openrisc: Use vaddr type for $pc jumps
 . 2367c94cbb1 target/openrisc: Remove target_ulong use in raise_mmu_exception()
 . 1843e89bec5 target/openrisc: Remove unused cpu_openrisc_map_address_*() handlers
 . a3c4facd395 target/openrisc: Do not use target_ulong for @mr in MTSPR helper
 . 2795bc52af4 target/openrisc: Replace VMSTATE_UINTTL() -> VMSTATE_UINT32()
