#  DEC Alphas running Digital Unix
#
# For DEC Alphas either -ieee_with_inexact or -ieee_with_no_inexact is
# needed. If you use only BDDs, -ieee_with_no_inexact is enough.
# In the following, we consider three different compilers:
# - the old native compiler (the one of MIPS ancestry that produces u-code);
# - the new native compiler;
# - gcc
# On the Alphas, gcc (as of release 2.7.2) does not support 32-bit pointers
# and IEEE 754 floating point arithmetic. Therefore, for this architecture
# only, the native compilers provide a substatial advantage.
# With the native compilers, specify -xtaso for 32-bit pointers.
# Do not use -xtaso_short because explicit reference to stdout and stderr
# does not work with this option. (Among other things.)
# Notice that -taso must be included in LDFLAGS for -xtaso to work.
# Given the number of possible choices, only some typical configurations
# are proposed here.
#
# Old native compiler for the Alphas; 64-bit pointers.
