Java's main JIT compiler devotes around 20% of its time to compiling garbage collection instrumentation code! By postponing instrumentation until the end of the compilation chain, we could reclaim this precious time at virtually no cost: robcasloz.github.io/blog/2024/02/1…

Program dependence graphs are the backbone of Java's main JIT compiler. They are powerful and efficient, but engineers find them complex and hard to debug. Luckily, HotSpot's IGV (the JIT visualizer) can now display them as good old control-flow graphs: robcasloz.github.io/blog/2022/05/2…

@FedorovMykhailo @SAP On behalf of Oracle’s 150,000 employees around the world and in support of both the elected government of Ukraine and for the people of Ukraine, Oracle Corporation has already suspended all operations in the Russian Federation.
#Swissgovernment Russia’s ongoing military attack on a sovereign European country is an extremely serious violation of international law. The Federal Council is therefore changing Switzerland’s stance on sanctions: admin.ch/gov/en/start/d… (BK)
