How to build hotspot jtreg test JNI with specific CFLAGS?
Hi, I'm trying to get a JNI library used for testing to be compiled with certain CFLAGS. In particular, I'm trying to get it compiled on a GCC platform with '-fomit-frame-pointer' and/or '-fomit-frame-pointer -O3'. The patch currently looks like this: diff --git a/make/test/JtregNativeHotspot.gmk b/make/test/JtregNativeHotspot.gmk --- a/make/test/JtregNativeHotspot.gmk +++ b/make/test/JtregNativeHotspot.gmk @@ -139,6 +139,13 @@ -I$(VM_TESTBASE_DIR)/nsk/share/native \ -I$(VM_TESTBASE_DIR)/nsk/share/jni +NO_FRAMEPOINTER_CFLAGS := +ifeq ($(OPENJDK_TARGET_OS),linux) + NO_FRAMEPOINTER_CFLAGS := -O3 -fomit-frame-pointer +endif + +BUILD_HOTSPOT_JTREG_LIBRARIES_CFLAGS_libNoFramePointer := $(NO_FRAMEPOINTER_CFLAGS) + BUILD_HOTSPOT_JTREG_LIBRARIES_CFLAGS_libProcessUtils := $(VM_SHARE_INCLUDES) BUILD_HOTSPOT_JTREG_LIBRARIES_CFLAGS_libThreadController := $(NSK_MONITORING_INCLUDES) When I look at the compile command line this produces with 'make run-test', I see this: $ cat ./build/linux-x86_64-normal-server-release/support/test/hotspot/jtreg/native/support/libNoFramePointer/libNoFramePointer.o.cmdline /usr/bin/gcc -I/disk/openjdk/upstream-sources/openjdk-head/build/linux-x86_64-normal-server-release/support/modules_include/java.base -I/disk/openjdk/upstream-sources/openjdk-head/build/linux-x86_64-normal-server-release/support/modules_include/java.base/linux -I/disk/openjdk/upstream-sources/openjdk-head/src/java.base/share/native/libjava -I/disk/openjdk/upstream-sources/openjdk-head/src/java.base/unix/native/libjava -I/disk/openjdk/upstream-sources/openjdk-head/src/hotspot/share/include -I/disk/openjdk/upstream-sources/openjdk-head/src/hotspot/os/posix/include -pipe -D_GNU_SOURCE -D_REENTRANT -D_LARGEFILE64_SOURCE -DLINUX -DNDEBUG -Wall -Wextra -Wno-unused -Wno-unused-parameter -Wformat=2 -fno-strict-aliasing -m64 -D_LITTLE_ENDIAN -DARCH='"amd64"' -Damd64 -D_LP64=1 -fno-omit-frame-pointer -fno-delete-null-pointer-checks -fno-lifetime-dse -fPIC -O3 -fomit-frame-pointer -g -O2 -DTHIS_FILE='""' -c -MMD -MF /disk/openjdk/upstream-sources/openjdk-head/build/linux-x86_64-normal-server-release/support/test/hotspot/jtreg/native/support/libNoFramePointer/libNoFramePointer.d -o /disk/openjdk/upstream-sources/openjdk-head/build/linux-x86_64-normal-server-release/support/test/hotspot/jtreg/native/support/libNoFramePointer/libNoFramePointer.o /disk/openjdk/upstream-sources/openjdk-head/test/hotspot/jtreg/serviceability/sa/libNoFramePointer.c The command line has '-O3 -fomit-frame-pointer -g -O2' in that order. This screws things up since -O2 seems to override -fomit-frame-pointer. My guess is that -O2 is from OPTIMIZATION == LOW, but not sure. How can I get this -O2 flag removed which apparently gets added later? Thanks, Severin

RE: 8202794: Native Unix code should use readdir rather than readdir_r
Hey, all; did this get resolved? I'm still getting this error in pulled-yesterday clones of jdk8u and jdk9 and jdk10. I would prefer not to make local changes (mostly I want to build debug builds so I can spelunk the JVM bits), but if this isn't going to roll out fairly shortly I'll disable warnings-as-errors and carry on.
