* LineIterator: Provide a variant that keeps blank linesJustin Bogner2014-09-171-1/+1
| | | | | | | | It isn't always useful to skip blank lines, as evidenced by the somewhat awkward use of line_iterator in llvm-cov. This adds a knob to control whether or not to skip blanks. llvm-svn: 217960
* Re-factor sample profile reader into lib/ProfileData.Diego Novillo2014-09-091-0/+238
Summary: This patch moves the profile reading logic out of the Sample Profile transformation into a generic profile reader facility in lib/ProfileData. The intent is to use this new reader to implement a sample profile reader/writer that can be used to convert sample profiles from external sources into LLVM. This first patch introduces no functional changes. It moves the profile reading code from lib/Transforms/SampleProfile.cpp into lib/ProfileData/SampleProfReader.cpp. In subsequent patches I will: - Add a bitcode format for sample profiles to allow for more efficient encoding of the profile. - Add a writer for both text and bitcode format profiles. - Add a 'convert' command to llvm-profdata to be able to convert between the two (and serve as entry point for other sample profile formats).
