8175bc3d3b llvm-symbolizer: add support for Mach-O universal binaries
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185137 91177308-0d34-0410-b5e6-96231b3b80d8

3df7d2f70b llvm-dwarfdump: Add support for dumping the .debug_loc section
This is a basic implementation - we still don't have any support (that I
know of) for dumping DWARF expressions in a meaningful way, so the
location information itself is just printed as a sequence of bytes as we
do elsewhere.

005159e924 Use zlib to uncompress debug sections in DWARF parser.
This makes llvm-dwarfdump and llvm-symbolizer understand
debug info sections compressed by ld.gold linker.

b05dc55460 AArch64: Add basic relocation processing for llvm-dwarfdump.
This allows llvm-dwarfdump to handle the relocations needed, at least
for LLVM-produced code.

62b055fd50 Add a test for checking the current .debug_frame dumping capability.
The test is a binary placed in test/DebugInfo/Inputs, with a source C
file used for reference/reproducing. The source's first line is a clang
build command for reproducing the binary.

ee7c0d2f93 Add support for applying in-memory relocations to the .debug_line section and, in the case of ELF files, using symbol addresses when available for relocations to the .debug_info section. Also extending the llvm-rtdyld tool to add the ability to dump line number information for testing purposes.

5eae90d727 Add support for fetching inlining context (stack of source code locations)
by instruction address from DWARF.

Add --inlining flag to llvm-dwarfdump to demonstrate and test this functionality,
so that "llvm-dwarfdump --inlining --address=0x..." now works much like
"addr2line -i 0x...", provided that the binary has debug info
(Clang's -gline-tables-only *is* enough).

351f83be64 Fix the representation of debug line table in DebugInfo LLVM library,
and "instruction address -> file/line" lookup.

Instead of plain collection of rows, debug line table for compilation unit is now
treated as the number of row ranges, describing sequences (series of contiguous machine
instructions). The sequences are not always listed in the order of increasing
address, so previously used std::lower_bound() sometimes produced wrong results.
Now the instruction address lookup consists of two stages: finding the correct
sequence, and searching for address in range of rows for this sequence.

9d26b0ba06 Improve behavior of DebugInfoEntryMinimal::getSubprogramName() introduced in r159512.
To fetch a subprogram name we should not only inspect the DIE for this subprogram, but optionally inspect
its specification, or its abstract origin (even if there is no inlining), or even specification of an abstract origin.

3e25c4a1e3 This patch extends the libLLVMDebugInfo which contains a minimalistic DWARF parser:
1) DIContext is now able to return function name for a given instruction address (besides file/line info).
2) llvm-dwarfdump accepts flag --functions that prints the function name (if address is specified by --address flag).
3) test case that checks the basic functionality of llvm-dwarfdump added
