Subject: libdecnumber: Modify dconfig.h to Integrate with QEMU
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7275585b8c0dda0720255c45489045b0c31092cc;p=qemu.git

libdecnumber: Modify dconfig.h to Integrate with QEMU

Modify the dconfig.h header file so that libdecnumber code integrates QEMU
configuration.   Specifically:

  - the WORDS_BIGENDIAN preprocessor macro is used in libdecnumber code to
    determines endianness.  It is derived from the existing QEMU macro
    HOST_WORDS_BIGENDIAN which is defined in config-host.h.

  - the DECPUN macro determines the number of decimal digits (aka declets) per
    unit (byte).  This is 3 for PowerPC DFP.
