wenzelm@27012: 
wenzelm@41579: This compilation of Poly/ML 5.4 is based on the official sources from
wenzelm@41579: http://www.polyml.org with the following patch from the SVN (which is
wenzelm@41578: also part of the fixes-5.4 source tree):

wenzelm@41578: Fix to arbitrary precision emulation for X86.  A GC during emulating
wenzelm@41578: an operation could cause the stack to move resulting in the result of
wenzelm@41578: the operation not being stored into the result register.

wenzelm@41578: The included build script is used like this:
wenzelm@41578: 
wenzelm@41578:   ./build src x86-linux --with-gmp
wenzelm@41578:   ./build src x86_64-linux --with-gmp

wenzelm@41578:   ./build src x86_64-darwin --without-gmp
wenzelm@41578:   ./build src x86-cygwin --with-gmp
wenzelm@41578: 
wenzelm@41578: The multi-platform directory layout for executables and shared
wenzelm@41578: libraries accommodates the standard ML_HOME settings for Isabelle.
wenzelm@27012: 
wenzelm@27012: 
wenzelm@41579: Also note that the separate "sha1" library module is required for
wenzelm@41579: efficient digesting of strings according to SHA-1.
