[PATCH v2 00/23] hw, target: Prefer fast cpu_env() over slower CPU QOM c


From: Philippe Mathieu-Daudé
Subject: [PATCH v2 00/23] hw, target: Prefer fast cpu_env() over slower CPU QOM cast macro
Date: Fri, 26 Jan 2024 23:03:42 +0100

Use cpu_env() -- which is fast path -- when possible.
Bulk conversion using Coccinelle spatch (script included).

Since v1:
- Avoid CPU() cast (Paolo)
- Split per targets (Thomas)

Philippe Mathieu-Daudé (23):
  hw/acpi/cpu: Use CPUState typedef
  scripts/coccinelle: Add cpu_env.cocci_template script
  bulk: Call in place single use cpu_env()
  target/alpha: Prefer fast cpu_env() over slower CPU QOM cast macro
  target/arm: Prefer fast cpu_env() over slower CPU QOM cast macro
  target/avr: Prefer fast cpu_env() over slower CPU QOM cast macro
  target/cris: Prefer fast cpu_env() over slower CPU QOM cast macro
  target/hppa: Prefer fast cpu_env() over slower CPU QOM cast macro
  target/i386/hvf: Use CPUState typedef
  target/i386: Prefer fast cpu_env() over slower CPU QOM cast macro
  target/m68k: Prefer fast cpu_env() over slower CPU QOM cast macro
  target/microblaze: Prefer fast cpu_env() over slower CPU QOM cast
    macro
  target/mips: Prefer fast cpu_env() over slower CPU QOM cast macro
  target/nios2: Prefer fast cpu_env() over slower CPU QOM cast macro
  target/openrisc: Prefer fast cpu_env() over slower CPU QOM cast macro
