Building on non-std architectures

[Dave Pointon]

Hi all,

Further to my previous e-mail, I've implemented a strawman IBM specific fix
(which bears all the hallmarks of working:-) as follows ...

diff --git a/common/autoconf/platform.m4 b/common/autoconf/platform.m4
--- a/common/autoconf/platform.m4
+++ b/common/autoconf/platform.m4
@@ -519,6 +519,12 @@
       AC_CHECK_SIZEOF([int *], [1111])

       TESTED_TARGET_CPU_BITS=`expr 8 \* $ac_cv_sizeof_int_p`
+
+      if test "x$ZERO_ARCHDEF" = xS390; then
+        if test "x$OPENJDK_TARGET_CPU_BITS" = x31; then
+          TESTED_TARGET_CPU_BITS=`expr $TESTED_TARGET_CPU_BITS - 1`
+        fi
+      fi

       if test "x$TESTED_TARGET_CPU_BITS" != "x$OPENJDK_TARGET_CPU_BITS";
then
         AC_MSG_ERROR([The tested number of bits in the target
($TESTED_TARGET_CPU_BITS) differs from the number of bits expected to be
found in the target ($OPENJDK_TARGET_CPU_BITS)])


Any advice etc. to make it [the above fix] more generically applicable will
be gratefully received.

TIA & rgds ,​

cost and before we we judge rightly of our strength to go thro' with it -
