From 2e5140849b021889cf4dd8df5d2352e508213607 Mon Sep 17 00:00:00 2001 From: Ian Rogers Date: Tue, 11 Nov 2025 13:21:50 -0800 Subject: [PATCH] perf expr: Add #target_cpu literal For CPU nanoseconds a lot of the stat-shadow metrics use either task-clock or cpu-clock, the latter being used when target__has_cpu. Add a #target_cpu literal so that json metrics can perform the same test.
