Chandler Carruth 802d755533 Sort includes for all of the .h files under the 'lib' tree. These were 
missed in the first pass because the script didn't yet handle include
guards.

Note that the script is now able to handle all of these headers without
manual edits. =]

Alexey Samsonov a1694c1aaf [DebugInfo] Generate address ranges for compile units even if .debug_aranges is present: it is often the case that .debug_aranges section contains ranges only for a small subset of compile units. Test cases will be added in separate commits.

Alexey Samsonov c942e6b781 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).

llvm-svn: 162659
 2012-08-27 07:24:43 +00:00
Alexey Samsonov 034e57a297 Add basic support for .debug_ranges section to LLVM's DebugInfo library. 
This section (introduced in DWARF-3) is used to define instruction address
ranges for functions that are not contiguous and can't be described
by low_pc/high_pc attributes (this is the usual case for inlined subroutines).
The patch is the first step to support fetching complete inlining info from DWARF.

Alexey Samsonov 947228c4f7 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.

Alexey Samsonov b604ff2a07 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.

Alexey Samsonov f4462fa3ca 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
