PATCH RESEND 1/3 perf tools: Use normalized arch name for searching objdump path

From: Namhyung Kim <[email protected]>

David reported that perf report for i686 target data on x86_64 host failed to work because it tried to find out cross-compiled objdump.

However objdump for x86_64 is compatible to i686 so that it doesn't need to do it at all. To prevent similar artifacts, normalize arch name when comparing host and file architectures.

PATCH 2/3 perf tools: Introduce struct hist_browser_timer

From: Namhyung Kim <[email protected]>

Currently various hist browser functions receive 3 arguments for refreshing histogram but only used from a few places. Also it's only for perf top command so that it can be NULL for other (and probably most) cases. Pack them into a struct in order to reduce number of those unused arguments.

This is a mechanical change and does not intend a functional change.

PATCH 3/3 perf report: Postpone objdump check until annotation requested

In reply to Namhyung Kim

From: Namhyung Kim <[email protected]>

David reported that current perf report refused to run on a data file captured from a different machine because of objdump. Since the objdump tools won't be used unless annotation was requested, checking its presence at init time doens't make sense.

David reported that perf report for i686 target data on x86_64 host failed to work because it tried to find out cross-compiled objdump.
However objdump for x86_64 is compatible to i686 so that it doesn't need to do it at all. To prevent similar artifacts, normalize arch name when comparing host and file architectures.

perf tools: Use normalized arch name for searching objdump path

David reported that perf report for i686 target data on x86_64 host failed to work because it tried to find out cross-compiled objdump.

However objdump for x86_64 is compatible to i686 so that it doesn't need to do it at all. To prevent similar artifacts, normalize arch name when comparing host and file architectures.
