perf tools: Don't try to lookup objdump for live mode

2012-11-08T20:26:52Z

Arnaldo reported that annotation during perf top resulted in a segfault. It was because the env->arch was NULL and we don't set it for a live session. In fact, no need to look up objdump in this case since we can use system's default (native) objdump.

perf tools: Use normalized arch name for searching objdump path

2012-11-05T17:03:58Z

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: Try to find cross-built objdump path

2012-10-24T16:20:11Z

As we have architecture information of saved perf.data file, we can try to find cross-built objdump path. The triplets include support for Android (arm, x86 and mips architectures).
