java - Linking error when building OpenJDK8 with gcc 6 -


i trying build openjdk 8 gcc6:

$ hg clone http://hg.openjdk.java.net/jdk8 jdk8 $ cd jdk8 $ bash get_source.sh $ bash ./configure $ make images

as explained here or here, had update make files add following options gcc:

-wno-deprecated-declarations  -wno-error=deprecated-declarations  -wno-error=narrowing  -fno-exceptions  -fvisibility=hidden  -fno-delete-null-pointer-checks  -fno-lifetime-dse

it seems compiles fine now. however, when linking fails on following command:

/usr/bin/x86_64-linux-gnu-gcc-6 -xlinker --hash-style=both -xlinker -z -xlinker defs -shared -l/home/johnd/src/build_jdk/jdk8/jdk/lib/amd64 -l/home/johnd/src/build_jdk/jdk8/jdk/lib/amd64/server -xlinker -z -xlinker origin -xlinker -rpath -xlinker \$origin -xlinker -version-script=/home/johnd/src/build_jdk/jdk8/jdk/make/mapfiles/libzip/mapfile-vers -xlinker -soname=libzip.so -o /home/johnd/src/build_jdk/jdk8/jdk/lib/amd64/libzip.so /home/johnd/src/build_jdk/jdk8/jdk/objs/libzip/adler32.o /home/johnd/src/build_jdk/jdk8/jdk/objs/libzip/crc32.o /home/johnd/src/build_jdk/jdk8/jdk/objs/libzip/deflater.o /home/johnd/src/build_jdk/jdk8/jdk/objs/libzip/inflater.o /home/johnd/src/build_jdk/jdk8/jdk/objs/libzip/zipfile.o /home/johnd/src/build_jdk/jdk8/jdk/objs/libzip/compress.o /home/johnd/src/build_jdk/jdk8/jdk/objs/libzip/deflate.o /home/johnd/src/build_jdk/jdk8/jdk/objs/libzip/gzclose.o /home/johnd/src/build_jdk/jdk8/jdk/objs/libzip/gzlib.o /home/johnd/src/build_jdk/jdk8/jdk/objs/libzip/gzread.o /home/johnd/src/build_jdk/jdk8/jdk/objs/libzip/gzwrite.o /home/johnd/src/build_jdk/jdk8/jdk/objs/libzip/infback.o /home/johnd/src/build_jdk/jdk8/jdk/objs/libzip/inffast.o /home/johnd/src/build_jdk/jdk8/jdk/objs/libzip/inflate.o /home/johnd/src/build_jdk/jdk8/jdk/objs/libzip/inftrees.o /home/johnd/src/build_jdk/jdk8/jdk/objs/libzip/trees.o /home/johnd/src/build_jdk/jdk8/jdk/objs/libzip/uncompr.o /home/johnd/src/build_jdk/jdk8/jdk/objs/libzip/zadler32.o /home/johnd/src/build_jdk/jdk8/jdk/objs/libzip/zcrc32.o /home/johnd/src/build_jdk/jdk8/jdk/objs/libzip/zip_util.o /home/johnd/src/build_jdk/jdk8/jdk/objs/libzip/zutil.o -ljvm -ljava

it gives following error:

/home/johnd/src/build_jdk/jdk8/jdk/objs/libzip/zipfile.o: in function `java_java_util_zip_zipfile_open': /home/johnd/src/build_jdk/jdk8/jdk/src/share/native/java/util/zip/zipfile.c:109: undefined reference `throwfilenotfoundexception' collect2: error: ld returned 1 exit status

this surprising since symbol `throwfilenotfoundexception' apparently defined in libjava given parameter linker.

$ nm ./jdk/lib/amd64/libjava.so | grep throw 000000000001b0cd t throwfilenotfoundexception 000000000001721b t throwioexception

any idea going on , how can fix it?

you seem have cloned jdk 8 ga sources (i.e. 2014). predate gcc6 2 years.

instead, please clone latest source code jdk 8 updates project, , try again, i.e.using hg.openjdk.java.net/jdk8u/jdk8u .

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
