Subject: [PATCH v1 4/4] perf build: Cleanup perf register configuration
Date: Wed, 14 Feb 2024 19:39:47 +0800 [thread overview]
Message-ID: <20240214113947.240957-5-leo.yan@linux.dev> (raw)
In-Reply-To: <20240214113947.240957-1-leo.yan@linux.dev>
The target is to allow the tool to always enable the perf register
feature for native parsing and cross parsing, and current code doesn't
depend on the macro 'HAVE_PERF_REGS_SUPPORT'.
This patch remove the variable 'NO_PERF_REGS' and the defined macro
'HAVE_PERF_REGS_SUPPORT' from the Makefile.
