[PATCH 0/6] Some vfprintf refactoring

[Florian Weimer <fweimer at redhat dot com>]

These patches move around some code in vfprintf, and finally split off
the positional argument handling code from the main vfprintf function.

Tested on x86_64-redhat-linux-gnu, with no regressions.

2015-03-01  Florian Weimer  <fweimer@redhat.com>

        * stdio-common/vfprintf.c (THOUSANDS_SEP_T): New typedef.
        (group_number, vfprintf): Use it.
        (JUMP_TABLE_BASE_LABEL): New preprocessor macro.
        (JUMP, REF): Use it.
        (WORK_BUFFER_SIZE): New preprocessor macro.
        (process_arg, vfprintf): Use it.
        (jump_table): Move out of the vfprintf function.
        (NOT_IN_JUMP_RANGE, CHAR_CLASS, LABEL, REF, JUMP, STEP0_3_TABLE,
        STEP4_TABLE, process_arg): Move macro definitions
        out of the vfprintf function.  (Cosmetic change only.)
        (vfprintf): Move local variables args_malloced, specs,
        specs_malloced, and the code after do_positional to the
        printf_positional function.
        (printf_positional): New function.
        (LABEL, JUMP_TABLE_BASE_LABEL, REF): Adjust jump table label
        generation macros.

Florian Weimer (6):
  vfprintf: Introduce THOUSANDS_SEP_T
  vfprintf: Introduce JUMP_TABLE_BASE_LABEL
  vfprintf: Define WORK_BUFFER_SIZE
  vfprintf: Move jump table definition and the macros out of function
  vfprintf: Introduce printf_positional function
  vfprintf: Remove label name switching for the jump table
