Improvements to 128-bit atomics:
- Separate __int128_t type and arithmetic detection - Support 128-bit load/store in backend for i386, aarch64, ppc64, s390x - Accelerate atomics via host/include/ Decodetree: - Add named field syntax - Move tests to meson -----BEGIN PGP SIGNATURE----- iQFRBAABCgA7FiEEekgeeIaLTbaoWgXAZN846K9+IV8FAmR2R10dHHJpY2hhcmQu aGVuZGVyc29uQGxpbmFyby5vcmcACgkQZN846K9+IV/bsgf/XLi8q+ITyoEAKwG4 6ML7DktLAdIs9Euah9twqe16U0BM0YzpKfymBfVVBKKaIa0524N4ZKIT3h6EeJo+ f+ultqrpsnH+aQh4wc3ZCkEvRdhzhFT8VcoRTunJuJrbL3Y8n2ZSgODUL2a0tahT Nn+zEPm8rzQanSKQHq5kyNBLpgTUKjc5wKfvy/WwttnFmkTnqzcuEA6nPVOVwOHC lZBQCByIQWsHfFHUVJFvsFzBQbm0mAiW6FNKzPBkoXon0h/UZUI1lV+xXzgutFs+ zR2O8IZwLYRu2wOWiTF8Nn2qQafkB3Dhwoq3JTEXhOqosOPExbIiWlsZDlPiKRJk bwmQlg== =XQMb -----END PGP SIGNATURE----- Merge tag 'pull-tcg-20230530' of https://gitlab.com/rth7680/qemu into staging Improvements to 128-bit atomics: - Separate __int128_t type and arithmetic detection - Support 128-bit load/store in backend for i386, aarch64, ppc64, s390x - Accelerate atomics via host/include/ Decodetree: - Add named field syntax - Move tests to meson # -----BEGIN PGP SIGNATURE----- # # iQFRBAABCgA7FiEEekgeeIaLTbaoWgXAZN846K9+IV8FAmR2R10dHHJpY2hhcmQu # aGVuZGVyc29uQGxpbmFyby5vcmcACgkQZN846K9+IV/bsgf/XLi8q+ITyoEAKwG4 # 6ML7DktLAdIs9Euah9twqe16U0BM0YzpKfymBfVVBKKaIa0524N4ZKIT3h6EeJo+ # f+ultqrpsnH+aQh4wc3ZCkEvRdhzhFT8VcoRTunJuJrbL3Y8n2ZSgODUL2a0tahT # Nn+zEPm8rzQanSKQHq5kyNBLpgTUKjc5wKfvy/WwttnFmkTnqzcuEA6nPVOVwOHC # lZBQCByIQWsHfFHUVJFvsFzBQbm0mAiW6FNKzPBkoXon0h/UZUI1lV+xXzgutFs+ # zR2O8IZwLYRu2wOWiTF8Nn2qQafkB3Dhwoq3JTEXhOqosOPExbIiWlsZDlPiKRJk # bwmQlg== # =XQMb # -----END PGP SIGNATURE----- # gpg: Signature made Tue 30 May 2023 11:58:37 AM PDT # gpg: using RSA key 7A481E78868B4DB6A85A05C064DF38E8AF7E215F # gpg: issuer "richard.henderson@linaro.org" # gpg: Good signature from "Richard Henderson <richard.henderson@linaro.org>" [ultimate] * tag 'pull-tcg-20230530' of https://gitlab.com/rth7680/qemu: (27 commits) tests/decode: Add tests for various named-field cases scripts/decodetree: Implement named field support scripts/decodetree: Implement a topological sort scripts/decodetree: Pass lvalue-formatter function to str_extract() docs: Document decodetree named field syntax tests/decode: Convert tests to meson decodetree: Do not remove output_file from /dev decodetree: Diagnose empty pattern group decodetree: Fix recursion in prop_format and build_tree decodetree: Add --test-for-error tcg: Remove TCG_TARGET_TLB_DISPLACEMENT_BITS accel/tcg: Add aarch64 store_atom_insert_al16 accel/tcg: Add aarch64 lse2 load_atom_extract_al16_or_al8 accel/tcg: Add x86_64 load_atom_extract_al16_or_al8 accel/tcg: Extract store_atom_insert_al16 to host header accel/tcg: Extract load_atom_extract_al16_or_al8 to host header tcg/s390x: Support 128-bit load/store tcg/ppc: Support 128-bit load/store tcg/aarch64: Support 128-bit load/store tcg/aarch64: Simplify constraints on qemu_ld/st ...
