Garbage Collector (parallel iversion) for ix86 DG/UX Release R4.20MU07
|
|
|
|
|
|
*READ* the file README.QUICK.
|
|
|
|
You need the GCC-3.0.3 rev (DG/UX) compiler to build this tree.
|
|
This compiler has the new "dgux386" threads package implemented.
|
|
It also supports the switch "-pthread" needed to link correctly
|
|
the DG/UX's -lrte -lthread with -lgcc and the system's -lc.
|
|
Finally we support parralleli-mark for the SMP DG/UX machines.
|
|
To build the garbage collector do:
|
|
|
|
./configure --enable-parallel-mark
|
|
make
|
|
make gctest
|
|
|
|
Before you run "gctest" you need to set your LD_LIBRARY_PATH
|
|
correctly so that "gctest" can find the shared library libgc.
|
|
Alternatively you can do a configuration
|
|
|
|
./configure --enable-parallel-mark --disable-shared
|
|
|
|
to build only the static version of libgc.
|
|
|
|
To enable debugging messages please do:
|
|
1) Add the "--enable-full-debug" flag during configuration.
|
|
2) Edit the file linux-threads.c and uncommnect the line:
|
|
|
|
/* #define DEBUG_THREADS 1 */ to --->
|
|
|
|
#define DEBUG_THREADS 1
|
|
|
|
Then give "make" as usual.
|
|
|
|
In a machine with 4 CPUs (my own machine) the option parallel
|
|
mark (aka --enable-parallel-mark) makes a BIG difference.

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