[DebugInfo] Expand ability to load 2-byte addresses in dwarf sections

2021-10-22T00:31:00+00:00

Some dwarf loaders in LLVM are hard-coded to only accept 4-byte and 8-byte address sizes. This patch generalizes acceptance into `DWARFContext::isAddressSizeSupported` and provides a common way to generate rejection errors.

The MSP430 target has been given new tests to cover dwarf loading cases that previously failed due to 2-byte addresses.

llvm-dwarfdump: Skip tombstoned address ranges

Make the dumper & API a bit more informative by using the new tombstone
addresses to filter out or otherwise render more explicitly dead code
ranges.

which directly or indirectly come to DataExtractor.

[DebugInfo] add SectionedAddress to DebugInfo interfaces.

2019-02-27T13:17:36+00:00

      That patch is the fix for https://bugs.llvm.org/show_bug.cgi?id=40703
   "wrong line number info for obj file compiled with -ffunction-sections"
   bug. The problem happened with only .o files. If object file contains
   several .text sections then line number information showed incorrectly.
   The reason for this is that DwarfLineTable could not detect section which
   corresponds to specified address(because address is the local to the
   section). And as the result it could not select proper sequence in the
   line table. The fix is to pass SectionIndex with the address. So that it
   would be possible to differentiate addresses from various sections. With
   this fix llvm-objdump shows correct line numbers for disassembled code.

Update the file headers across all of the LLVM projects in the monorepo

2019-01-19T08:50:56+00:00

to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

[DWARF][NFC] Refactor range list extraction and dumping

2018-10-29T22:16:47+00:00

The purpose of this patch is twofold: 
- Fold pre-DWARF v5 functionality into v5 to eliminate the need for 2 different 
  versions of range list handling. We get rid of DWARFDebugRangelist{.cpp,.h}.
- Templatize the handling of range list tables so that location list handling
  can take advantage of it as well. Location list and range list tables have the 
  same basic layout.

A non-NFC version of this patch was previously submitted with r342218, but it caused
errors with some TSan tests. This patch has no functional changes. The difference to
the non-NFC patch is that there are no changes to rangelist dumping in this patch.

DebugInfo: Use debug_addr for non-dwo addresses in DWARF 5

2018-10-20T06:02:15+00:00

Putting addresses in the address pool, even with non-fission, can reduce
relocations - reusing the addresses from debug_info and debug_rnglists
(the latter coming soon)

Revert "[DWARF] reposting r342048, which was reverted in r342056 due to buildbot errors. Adjusted 2 test cases for ARM and darwin and fixed a bug with the original change in dsymutil."

2018-09-17T15:40:01+00:00

This reverts commit r342218. Due to a number of failures under TSAN. An isolated
test case is being worked on.
