[PATCH v4 00/16] tcg: Improvements to atomic128
Posted by Richard Henderson 1 week, 2 days ago
This is a merge of a couple of singleton fixes, CONFIG_ATOMIC128
detection, and tcg backend code generation patch sets, just to
keep everything in one place.

Tested with the Arm FEAT_LSE2 patch set, which greatly increases
the number of 16-byte atomic operations.

Patches needing review:
  01-tcg-Fix-register-move-type-in-tcg_out_ld_helper_r.patch
  02-accel-tcg-Fix-check-for-page-writeability-in-load.patch
  03-meson-Split-test-for-__int128_t-type-from-__int12.patch
  05-tcg-i386-Support-128-bit-load-store.patch
  07-tcg-aarch64-Reserve-TCG_REG_TMP1-TCG_REG_TMP2.patch
  08-tcg-aarch64-Simplify-constraints-on-qemu_ld-st.patch
  12-accel-tcg-Extract-load_atom_extract_al16_or_al8-t.patch
  13-accel-tcg-Extract-store_atom_insert_al16-to-host-.patch
  14-accel-tcg-Add-x86_64-load_atom_extract_al16_or_al.patch
  15-accel-tcg-Add-aarch64-lse2-load_atom_extract_al16.patch
  16-accel-tcg-Add-aarch64-store_atom_insert_al16.patch
