[Qemu-devel] [PATCH 0/7] Remove pre ANSI c89 code

[Juan Quintela]

Hi

In commemoration of the 20th anniversary of the c89 standard, this brings
qemu codebase to c89.  How do I know?

Previous to last patch adds to QEMU_CFLAGS:
  -Wold-style-declaration -Wold-style-definition

Why?
- typedef abuse for the 1st patch.  How that ever worked, I don't know.
- gcc gets picky, and you have to declare functions as:
   static inline void f(...)
   inline static void f(...)
  but
   static void inline f(...)
  gets warnings.  Just move the few functions that have the third
  format to the 1st one.
- bring alpha-dis.c and sh4-dis.c to ansi c89 function declaration.
- static + const: gcc wants you to use:
      static const
  and gives a warning for
      const static
- same for static + __thread (only 1 occurrence)
- last patch removes PARAMS() from dis-asm.h
  last users were alpha-dis.c and sh4-dis.c (do you start to see a
  pattern here).

Last one is not required, but as qemu is not going to compile in pre-c89
compiler any time soon, it is better to also apply it.

Later, Juan.


Juan Quintela (7):
  Use proper typedef syntax
  static and inline should came before the type of the functions
  Bring two last users of K&R definitions to ANSI c89
  gcc wants 1st static and then const
  __thread should be before real type
  Add -Wold-style-declaration -Wold-style-definition to QEMU_CFLAGS
  Remove PARAMS() macro
