To build readtest - the tests for the Intel(R) Decimal Floating-Point Math 
Library V2.4 (Version 2, Update 4) on processors that are implementations of the
Intel(R) 64 Architecture:  

  In Linux* with icx (Intel(R) C++ Compiler 2025.0 or newer) or gcc:

    make clean OS_TYPE=LINUX
    make OS_TYPE=LINUX CC=icx CALL_BY_REF=0 GLOBAL_RND=0 GLOBAL_FLAGS=0 UNCHANGED_BINARY_FLAGS=0
      - CC can be icx, icc, gcc, clang
      - CALL_BY_REF, GLOBAL_RND, GLOBAL_FLAGS, UNCHANGED_BINARY_FLAGS can be any of 0000, 0001, ... , 1111

  In Windows** with icx (Intel(R) C++ Compiler 2025.0 or newer) or cl (Microsoft
  Visual C++ Compiler**):  

    nmake clean OS_TYPE=WIN
    nmake -fmakefile.mak CC=icl CALL_BY_REF=0 GLOBAL_RND=0 GLOBAL_FLAGS=0 UNCHANGED_BINARY_FLAGS=0
      -  CC can be cl, icx, icl, clang
      -  CALL_BY_REF, GLOBAL_RND, GLOBAL_FLAGS, UNCHANGED_BINARY_FLAGS can be any of 0000, 0001, ... , 1111
      -  [g]make which stands for a GNU make-compatible make program (e.g. make from
         cygwin) can also be used

    Note: The scripts and makefiles provided here may need adjustments, 
        depending on the environment in which they are used; for example if 
        moving files from Windows to Linux, running dos2unix on the Linux 
        script files may be necessary.

To run readtest:
    ./readtest < readtest.in (Linux)
    readtest < readtest.in (Windows)     

Note: 
=====
  For other operating systems and architecture combinations see for example the following
  command files (or other RUN* command files provided here), as well as any command files
  invoked from these ones:
        RUNLINUXINTEL64_ICX
        RUNWINDOWSINTEL64_CL.bat
  These command files build and run the tests from this directory.
  Changes may be necessary in certain environments. However, prior to
  building these tests the similar RUN* command has to be executed in
  ../LIBRARY/ in order to build all the necessary versions of the Intel(R)
  Decimal Floating-Point Math Library. The tests [when built correctly] pass
  if the word FAIL does not appear in the output.


Note:
=====
If the makefile provided here is not used, the parameter passing method and  
local/global rounding mode and status flags may be selected by editing  
test_bid_conf.h:

Parameter passing is determined by an environment variable in test_bid_conf.h:
  - by value:
        #define DECIMAL_CALL_BY_REFERENCE 0
  - by reference:
        #define DECIMAL_CALL_BY_REFERENCE 1
 
Global variables are determined by two environment variables in test_bid_conf.h:
  - rnd_mode passed as parameter
        #define DECIMAL_GLOBAL_ROUNDING 0
  - rnd_mode global
        #define DECIMAL_GLOBAL_ROUNDING 1
  - status flags *pfpsf passed as parameter
        #define DECIMAL_GLOBAL_EXCEPTION_FLAGS 0
  - status flags *pfpsf global
        #define DECIMAL_GLOBAL_EXCEPTION_FLAGS 1
