javascript - How to select :host with a class in css for web components? -


in new v1 web components specs, can use :host target custom element. attached class a custom element, , had css selector :host.a, styles not being applied. know how fix this?

thanks

as per documentation:

for example, had component shadow tree following:

<x-foo class="foo">     <"shadow tree">         <div class="foo">...</div>     </> </x-foo>

for stylesheet within shadow tree:

  • ...
  • ':host(.foo)' matches <x-foo> element.

as op has commented, would, in case, translate to:

:host(.a) {     ... }

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 ...
