Alexey Samsonov	762343da6c	[DWARF parser] Refactor fetching DIE address ranges. Add a helper method to get address ranges specified in a DIE (either by DW_AT_low_pc/DW_AT_high_pc, or by DW_AT_ranges). Use it to untangle and simplify the code. No functionality change. llvm-svn: 206624	2014-04-18 17:25:46 +00:00
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: 163128	2012-09-04 08:12:33 +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. Reviewed by Benjamin Kramer. llvm-svn: 162657	2012-08-27 07:17:47 +00:00

[DWARF parser] Refactor fetching DIE address ranges.

Add a helper method to get address ranges specified in a DIE
(either by DW_AT_low_pc/DW_AT_high_pc, or by DW_AT_ranges). Use it
to untangle and simplify the code.

No functionality change.

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).

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.
