cmake - Can parameter DESTINATION for INSTALL be empty? -


in general, relative parameters of type path, "lib" or "source/include" resolved in cmake absolute path using current value of variables, instance: ${cmake_install_prefix} in case of command install. this, however, not work if use empty relative path (or not set @ all), resulting absolute path equal ${cmake_install_prefix} - cmake generator complain non existing destination, although there no reason why couldn't resolved.

i know 2 workarounds issue, both have flaws prevent me achieving goal:

  1. use ${cmake_install_prefix} destination value. correctly resolved path, in case of install(export), paths in generated target.cmake absolute, makes package not relocatable.

  2. use . destination. @ least generates relative paths inside target.cmake, paths incorrect. . apparently considered regular folder, , in process of target.cmake generation, when _import_prefix determined, cmake strips 1 folder component much:

    # compute installation prefix relative file. get_filename_component(_import_prefix "${cmake_current_list_file}" path) get_filename_component(_import_prefix "${_import_prefix}" path)

is there other workaround? think lack of empty relative paths considered bug?

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 ...
