[DebugInfo] Convert most tests to opaque pointers (NFC)

[Sparc] Convert tests to check 'target=sparc.*'

2022-12-01T19:41:30+00:00

Part of the project to eliminate special handling for triples in lit
expressions.

Generalize DWARF tests that expect DW_FORM_strp

2021-10-27T03:42:50+00:00

The modified tests were failing on AIX because DWARF on AIX uses inline strings by default, but the tests check for `DW_FORM_strp`.

This patch removes `DW_FORM_strp` so both forms will pass the check.

[test] XFAIL two tests with inlining debug info issues on Sparc

2020-08-13T09:12:52+00:00

Currently only two test failures remain on Sparc, both
`sparcv9-sun-solaris2.11` and `sparc64-unknown-linux-gnu`:

  LLVM :: DebugInfo/Generic/debug-label-inline.ll
  LLVM :: Linker/subprogram-linkonce-weak.ll

They seem related in that debug info isn't generated for instruction
bundles (like `retl+add` in the delay slot).

I've filed separate bugs for both files (Bug 47129 and 47131), though it's
probably the same issue.

This patch `XFAIL`s the tests.

Tested on `sparcv9-sun-solaris2.11` and `amd64-pc-solaris2.11`.

[DebugInfo] Fix debug information label tests

2018-10-08T22:10:34+00:00

Remove the space in the asm check so that the expression is more general
and can also capture MIPS labels which can be surrounded by braces, e.g.:

.4byte        ($tmp1)                 # DW_AT_low_pc

Also change optimization level to O0 because the DW_TAG_label does not
appear on MIPS when -O2 is used.

[DebugInfo] Generate DWARF debug information for labels. (Fix leak problems)

2018-08-17T15:22:04+00:00

There are two forms for label debug information in DWARF format.

1. Labels in a non-inlined function:

DW_TAG_label
  DW_AT_name
  DW_AT_decl_file
  DW_AT_decl_line
  DW_AT_low_pc

2. Labels in an inlined function:

DW_TAG_label
  DW_AT_abstract_origin
  DW_AT_low_pc

We will collect label information from DBG_LABEL. Before every DBG_LABEL,
we will generate a temporary symbol to denote the location of the label.
The symbol could be used to get DW_AT_low_pc afterwards. So, we create a
mapping between 'inlined label' and DBG_LABEL MachineInstr in DebugHandlerBase.
The DBG_LABEL in the mapping is used to query the symbol before it.

The AbstractLabels in DwarfCompileUnit is used to process labels in inlined
functions.

We also keep a mapping between scope and labels in DwarfFile to help to
generate correct tree structure of DIEs.

It also generates label debug information under global isel.
