Re: [PATCH 1/2] Check trace data from trace file


Here is the same patch with spaces ignored.  It is easier to read.
Note that I modified a matched pattern "PC register is not
available" for tfile target, as the regcache is not available when
switch to tfind mode (no regcache has been read out of 'R' block yet).
