Subject: [PATCH] selftest/powerpc/pmu/ebb: remove fixed_instruction.S
Date: Tue, 22 Mar 2022 10:26:38 +0530	[thread overview]
Message-ID: <20220322045638.10443-1-maddy@linux.ibm.com> (raw)

Commit 3752e453f6ba ("selftests/powerpc: Add tests of PMU EBBs") added
selftest testcases to verify EBB interface. instruction_count_test.c
testcase needs a fixed loop function to count overhead. Instead of
using the thirty_two_instruction_loop() in fixed_instruction_loop.S
in ebb folder, file is linked with thirty_two_instruction_loop() in
loop.S from top folder. Since fixed_instruction_loop.S not used, patch
removes the file.
