perf tests: Add parse metric test for ipc metric
Adding new test that process metrics code and checks the expected
results. Starting with easy ipc metric.
Committer testing:
# perf test "Parse and process metrics"
67: Parse and process metrics : Ok
#
# perf test -v "Parse and process metrics"
67: Parse and process metrics :
--- start ---
test child forked, pid 103402
metric expr inst_retired.any / cpu_clk_unhalted.thread for IPC
found event inst_retired.any
found event cpu_clk_unhalted.thread
adding {inst_retired.any,cpu_clk_unhalted.thread}:W
test child finished with 0
---- end ----
Parse and process metrics: Ok
#
Had to fix it to initialize that 'struct value' array sentinel with a
named initializer to fix the build with some versions of clang:
tests/parse-metric.c:135:7: error: missing field 'val' initializer [-Werror,-Wmissing-field-initializers]
{ 0 },
