4bd0224887a8de1434186cad2f618c18dea06c0b 14-Nov-2013 Yuchen Wu <yuchenericwu@hotmail.com> llvm-cov: Slightly improved error checking.

- readInt() should check all 4 bytes can be read, not just 1.
- In the event of false data in the gcno file, it was possible to index
into a non-existent index of SmallVector, causing assertion error.

131a764e0e7abc90b322fd568e042d3c5a0633af 14-Nov-2013 Yuchen Wu <yuchenericwu@hotmail.com> llvm-cov: Removed StringMap holding GCOVLines.

According to the hazy gcov documentation, it appeared to be technically
possible for lines within a block to belong to different source files.
However, upon further investigation, gcov does not actually support
multiple source files for a single block.

This change removes a level of separation between blocks and lines by
replacing the StringMap of GCOVLines with a SmallVector of ints
representing line numbers. This also means that the GCOVLines class is
no longer needed.

This paves the way for supporting the "-a" option, which will output
block information.

dbb51ff01fd08df39e5040c1cd9edacdc3e4308a 14-Nov-2013 Yuchen Wu <yuchenericwu@hotmail.com> llvm-cov: Replaced asserts with proper error handling.

Unified the interface for read functions. They all return a boolean
indicating if the read from file succeeded. Functions that previously
returned the read value now store it into a variable that is passed in
by reference instead. Callers will need to check the return value to
detect if an error occurred.

Also added a new test which ensures that no assertions occur when file
contains invalid data. llvm-cov should return with error code 1 upon
failure.

e85959cb2cb6f82959b3cf1a9ef59c6d793a2556 05-Nov-2013 Yuchen Wu <yuchenericwu@hotmail.com> Support for reading run counts in llvm-cov.

This patch enables llvm-cov to correctly output the run count stored in
the GCDA file. GCOVProfiling currently does not generate this
information, so the GCDA run data had to be hacked on from a GCDA file
generated by gcc. This is corrected by a subsequent patch.

With the run and program data included, both llvm-cov and gcov produced
the same output.

Added -o option to llvm-cov. If no output file is specified, it defaults
to STDOUT.

llvm-cov will now be able to read program counts from the GCDA file and
output it in the same format as gcov. The program summary tag was
identified from gcov-io.h as "\0\0\0\a3".

There is currently a bug in GCOVProfiling.cpp which does not generate
the
run- or program-counting IR, so this change was tested manually by
modifying the GCDA file and comparing the gcov and llvm-cov outputs.

cbbd20879e8acf35d3326a2459e17a298b5f5d15 24-Oct-2013 Yuchen Wu <yuchenericwu@hotmail.com> Fixed llvm-cov to count edges instead of blocks.

This was a fundamental flaw in llvm-cov where it treated the values in
the GCDA files as block counts instead of edge counts. This created
incorrect line counts when branching was present. Instead, the edge
counts should be summed to obtain the correct block count.

The fix was tested using custom test files as well as single source
files from the test-suite directory. The behaviour can be verified by
reading the GCOV documentation that describes the GCDA spec ("ARC_COUNTS
gives the counter values for those arcs that are instrumented") and the
header description provided by GCOVProfiling.cpp ("instruments the code
that runs to records (sic) the edges between blocks that run and emit a
complementary "gcda" file on exit").

9db9663d1d2e4e336c2787bacff4ee7125622e21 23-Oct-2013 Yuchen Wu <yuchenericwu@hotmail.com> Use a map instead of vector to store line counts.

There are a few motivations for this:
- Using a map allows for checking if line is in map. This differentiates
unexecutable lines (such as comments) from unexecuted logical lines of
code. "#####" is now outputted in this case, in line with gcov.
- Source files are no longer read in twice: once when storing the line
counts, and once when outputting the data.
- Greatly simplifies the function FileInfo::addLineCount().

51ec77d880ce53cbc8a48168185edc085df9b6d9 22-Oct-2013 Bob Wilson <bob.wilson@apple.com> Fix llvm-cov counts to be 64-bit integers to avoid overflows.

Line counts in llvm-cov are read in as 64-bit integers but were being truncated
to 32-bit in collectLineCounts(), which caused overflow for large counts.
This patch fixes all counts to be uint64_t.

e877eebfe9d716ed1101aecf958af473836e70e1 22-Oct-2013 Bob Wilson <bob.wilson@apple.com> Change llvm-cov output formatting to be more similar to gcov.

- Replaced tabs with proper padding
- print() takes two arguments, which are the GCNO and GCDA filenames
- Files are listed at the top of output, appended by line 0
- Stripped strings of trailing \0s
- Removed last two lines of whitespace in output
