[PATCH] perf test: Compile named_threads workload with -O0
From: James Clark
Date: Thu Jun 11 2026 - 07:18:56 EST
The work loop relies on the compiler not optimizing it away, although
named_threads_work is not static for that reason, the compiler could
still do it.
Fix it by compiling without optimization. Also add -fno-inline for
consistency and in case anyone wants to look at callstacks.

One trailing Sashiko fix from the "perf cs-etm: Queue context packets
for frontend" patch series that has been applied already.
