1.1 ! noro 1: Garbage Collector (parallel iversion) for ix86 DG/UX Release R4.20MU07
! 2:
! 3:
! 4: *READ* the file README.QUICK.
! 5:
! 6: You need the GCC-3.0.3 rev (DG/UX) compiler to build this tree.
! 7: This compiler has the new "dgux386" threads package implemented.
! 8: It also supports the switch "-pthread" needed to link correctly
! 9: the DG/UX's -lrte -lthread with -lgcc and the system's -lc.
! 10: Finally we support parralleli-mark for the SMP DG/UX machines.
! 11: To build the garbage collector do:
! 12:
! 13: ./configure --enable-parallel-mark
! 14: make
! 15: make gctest
! 16:
! 17: Before you run "gctest" you need to set your LD_LIBRARY_PATH
! 18: correctly so that "gctest" can find the shared library libgc.
! 19: Alternatively you can do a configuration
! 20:
! 21: ./configure --enable-parallel-mark --disable-shared
! 22:
! 23: to build only the static version of libgc.
! 24:
! 25: To enable debugging messages please do:
! 26: 1) Add the "--enable-full-debug" flag during configuration.
! 27: 2) Edit the file linux-threads.c and uncommnect the line:
! 28:
! 29: /* #define DEBUG_THREADS 1 */ to --->
! 30:
! 31: #define DEBUG_THREADS 1
! 32:
! 33: Then give "make" as usual.
! 34:
! 35: In a machine with 4 CPUs (my own machine) the option parallel
! 36: mark (aka --enable-parallel-mark) makes a BIG difference.

! 47: Note (HB):
! 48: The integration of this patch is currently not complete.
! 49: The following patches against 6.1alpha3 where hard to move
! 50: to alpha4, and are not integrated. There may also be minor
! 51: problems with stylistic corrections made by me.
