[Qemu-devel] [PATCH 04/37] libdecnumber: Modify dconfig.h to Integrate w


From: Tom Musta
Subject: [Qemu-devel] [PATCH 04/37] libdecnumber: Modify dconfig.h to Integrate with QEMU
Date: Fri, 18 Apr 2014 09:50:08 -0500

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.
