Subject: [PATCH v1] perf build: Move libopcode disasm tests to BUILD_NONDISTRO
Date: Thu, 2 Oct 2025 19:39:28 -0700 [thread overview]
Message-ID: <20251003023928.2433640-1-irogers@google.com> (raw)
The disasm feature tests feature-disassembler-four-args and
feature-disassembler-init-styled link against libopcodes part of
binutils which is license incompatible (GPLv3) with perf. Moving these
tests out of the common config will help improve build time.
