Saleem Abdulrasool 5b060a92d6 llvm-readobj: address review comments for ARM EHABI printing
Rename bytecode to opcodes to make it more clear.  Change an impossible case to
llvm_unreachable instead.  Avoid allocation of a buffer by modifying the
PrintOpcodes iteration.

Saleem Abdulrasool 7e34cc4dbd tests: disable ARM unwinding tests if ARM is unavailable
Appease the buildbots for targets which do not build the ARM support by moving
the ARM specific test into a subdirectory and use the lit configuration to
disable them appropriately.

Thanks to chapuni and thakis for explaining how to do this!

Saleem Abdulrasool be981ebcf0 llvm-readobj: add support for ARM EHABI unwind info
This adds some preliminary support for decoding ARM EHABI unwinding information.
The major functionality that remains from complete support is bytecode
translation.

Each Unwind Index Table is printed out as a separate entity along with its
section index, name, offset, and entries.

Each entry lists the function address, and if possible, the name, of the
function to which it corresponds.  The encoding model, personality routine or
index, and byte code is also listed.

Yuchen Wu bb6a477131 llvm-cov: Added -f option for function summaries.
Similar to the file summaries, the function summaries output line,
branching and call statistics. The file summaries have been moved
outside the initial loop so that all of the function summaries can be
outputted before file summaries.

Also updated test cases.

Yuchen Wu 8256ee6d4a llvm-cov: Print coverage summary to STDOUT.
File summaries will now be optionally outputted which will give line,
branching and call coverage info. Unfortunately, clang's current
instrumentation does not give enough information to deduce function
calls, something that gcc is able to do. Thus, no calls are always
outputted to be consistent with gcov output.

Also updated tests.

Yuchen Wu 342714c11c llvm-cov: Added -b option for branch probabilities.
This option tells llvm-cov to print out branch probabilities when
a basic block contains multiple branches. It also prints out some
function summary info including the number of times the function enters,
the percent of time it returns, and how many blocks were executed.

Also updated tests.

Yuchen Wu 8c6bb5f4d4 llvm-cov: Added -a option for block data.
Similar to gcov, llvm-cov will now print out the block count at the end
of each block. Multiple blocks can end on the same line.

One computational difference is by using -a, llvm-cov will no longer
simply add the block counts together to form a line count. Instead, it
will take the maximum of the block counts on that line. This has a
similar effect to what gcov does, but generates more correct counts in
certain scenarios.

Also updated tests.

Daniel Jasper 2a2ed02069 Copy input files to test directory.
With r196184, llvm-cov creates a new file right next to the input file.
However, the Inputs-directory can't simply be assumed to be writable
under all build systems.

Also, this prevents a new source file from showing up in the source tree
if the test aborts before the call to "rm".

Yuchen Wu 26326ad396 llvm-cov: Removed output to STDOUT/specified file.
Instead of asking the user to specify a single file to output coverage
info and defaulting to STDOUT, llvm-cov now creates files for each
source file with a naming system of: <source filename> + ".llcov".

This is what gcov does and although it can clutter the working directory
with numerous coverage files, it will be easier to hook the llvm-cov
output to tools which operate on this assumption (such as lcov).

Yuchen Wu babe749125 llvm-cov: Added file checksum to gcno and gcda files.
Instead of permanently outputting "MVLL" as the file checksum, clang
will create gcno and gcda checksums by hashing the destination block
numbers of every arc. This allows for llvm-cov to check if the two gcov
files are synchronized.

Regenerated the test files so they contain the checksum. Also added
negative test to ensure error when the checksums don't match.

Yuchen Wu d738beec44 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.

Yuchen Wu e28da84c96 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.

This test compares the output of llvm-cov against a coverage file

others). These platforms are marked as XFAIL for now, but will be fixed
later.

Yuchen Wu b9a29f2782 Revert "Added basic unit test for llvm-cov."
This reverts commit r194451.

Not sure why the tests are failing on the buildbot. They run fine on my
local machine. Could it possibly be because of the endianness of the
architectures? The GCNO and GCDA files are little-endian encoded, and
llvm-cov expects it to remain that way. Is this a safe assumption?

Rui Ueyama 5b1adbaad9 llvm-objdump: Dump COFF import table if -private-headers option is given.
This is a patch to add capability to llvm-objdump to dump COFF Import Table
entries, so that we can write tests for LLD checking Import Table contents.

llvm-objdump did not print anything but just file name if the format is COFF
and -private-headers option is given. This is a patch adds capability for
dumping DLL Import Table, which is specific to the COFF format.

In this patch I defined a new iterator to iterate over import table entries.
Also added a few functions to COFFObjectFile.cpp to access fields of the entry.
