Hi David, Magnus, compiles and works fine on AIX, but as mentioned before off-list to David I see this stdout:
configure: No CLOCK_GETTIME_IN_LIBRT configure: No CLOCK_GETTIME_IN_LIBRT Also, the -DSUPPORTS_CLOCK_MONOTONIC appears twice on the command line. Full compile command looks like this: /bin/xlC_r -q64 -qpic -D_REENTRANT -D__STDC_FORMAT_MACROS -DSUPPORTS_CLOCK_MONOTONIC -DSUPPORTS_CLOCK_MONOTONIC -DAIX -qtune=balanced -qalias=noansi -qstrict -qtls=default -qlanglvl=c99vla -qlanglvl=noredefmac -qnortti -qnoeh -qignerrno -qarch=ppc64 -DASSERT -DTARGET_ARCH_ppc -DINCLUDE_SUFFIX_OS=_aix -DINCLUDE_SUFFIX_CPU=_ppc -DTARGET_COMPILER_xlc -DPPC64 -DHOTSPOT_LIB_ARCH='"ppc64"' -DCOMPILER1 -DCOMPILER2 -DINCLUDE_JVMCI=0 -I/priv/d031900/openjdk/jdk10-hs/source/hotspot/src/share/vm -I/priv/d031900/openjdk/jdk10-hs/source/hotspot/src/os/aix/vm -I/priv/d031900/openjdk/jdk10-hs/source/hotspot/src/os/posix/vm -I/priv/d031900/openjdk/jdk10-hs/source/hotspot/src/cpu/ppc/vm -I/priv/d031900/openjdk/jdk10-hs/source/hotspot/src/os_cpu/aix_ppc/vm -I/priv/d031900/openjdk/jdk10-hs/output/hotspot/variant-server/gensrc -I/priv/d031900/openjdk/jdk10-hs/source/hotspot/src/share/vm/precompiled -I/priv/d031900/openjdk/jdk10-hs/source/hotspot/src/share/vm/prims -DDONT_USE_PRECOMPILED_HEADER -g -qsuppress=1540-0216 -qsuppress=1540-0198 -qsuppress=1540-1090 -qsuppress=1540-1639 -qsuppress=1540-1088 -qsuppress=1500-010 -O3 -qhot=level=1 -qinline -qinlglue -DTHIS_FILE='"os_posix.cpp"' -c -qmakedep=gcc -MF /priv/d031900/openjdk/jdk10-hs/output/hotspot/variant-server/libjvm/objs/os_posix.d -o /priv/d031900/openjdk/jdk10-hs/output/hotspot/variant-server/libjvm/objs/os_posix.o /priv/d031900/openjdk/jdk10-hs/source/hotspot/src/os/posix/vm/os_posix.cpp -DSUPPORTS_CLOCK_MONOTONIC is the only switch appearing twice. I'm baffled. Do you have any idea?
