The "Simple expression parser" test fails on powerpc
as below:

 parsing metric: #system_tsc_freq
 Unrecognized literal '#system_tsc_freq'literal: #system_tsc_freq = nan
 syntax error
 FAILED tests/expr.c:247 #system_tsc_freq
 ---- end(-1) ----
 7: Simple expression parser  : FAILED!

In the test, system_tsc_freq is checked as below:

 if (is_intel)
    TEST_ASSERT_VAL("#system_tsc_freq > 0", val > 0);
 else

But commit 609aa2667f67 ("perf tool_pmu: Switch to standard
pmu functions and json descriptions")' changed condition in
tool_pmu__skip_event so that system_tsc_freq event should
only appear on x86

 +#if !defined(__i386__) && !defined(__x86_64__)
 +       /* The system_tsc_freq event should only appear on x86. */
 +       if (strcasecmp(name, "system_tsc_freq") == 0)
 +               return true;
 +#endif

After this commit, the testcase breaks for expr__parse of
system_tsc_freq in powerpc case. Fix the testcase to have
complete system_tsc_freq test within "is_intel" check.

Probably need to put it as Fixes: tag.

Ian, are you ok with this?

Thanks,

Hi Ian

If the change looks good to you, I will send a V2 with Fixes tag added. Please share your review comments

Hi James, Thomas

Looking for help to test since in non-intel platform, this test will fail without the patch

Thanks
Athira

Hi Athira,

sorry for the breakage and thank you for the detailed explanation. As
the code will run on AMD I think your change will break that - . It is
probably safest to keep the ".. else { .." for this case but guard it
in the ifdef.

Thanks,
Ian
