Support for DW_FORM_implicit_const DWARFv5 feature. When this form is used attribute value goes to .debug_abbrev section (as SLEB). As this form would break any debug tool which doesn't support DWARFv5 it is guarded by dwarf version check. Attempt to use this form with dwarf version <= 4 is considered a fatal error.

This patch gets a DWARF parsing speed improvement by having DWARFAbbreviationDeclaration instances know if they have a fixed byte size. If an abbreviation has a fixed byte size that can be calculated given a DWARFUnit, then parsing a DIE becomes two steps: parse ULEB128 abbrev code, and then add constant size to the offset. This patch also adds a fixed byte size to each DWARFAbbreviationDeclaration::AttributeSpec so that attributes can quickly skip their values if needed without the need to lookup the fixed for size. Notable improvements: - DWARFAbbreviationDeclaration::findAttributeIndex() now returns an Optional<uint32_t> instead of a uint32_t and we no longer have to look for the magic -1U return value - Optional<uint32_t> DWARFAbbreviationDeclaration::findAttributeIndex(dwarf::Attribute attr) const; - DWARFAbbreviationDeclaration now has a getAttributeValue() function that extracts an attribute value given a DIE offset that takes advantage of the DWARFAbbreviationDeclaration::AttributeSpec::ByteSize - bool DWARFAbbreviationDeclaration::getAttributeValue(const uint32_t DIEOffset, const dwarf::Attribute Attr, const DWARFUnit &U, DWARFFormValue &FormValue) const; - A DWARFAbbreviationDeclaration instance can return a fixed byte size for itself so DWARF parsing is faster: - Optional<size_t> DWARFAbbreviationDeclaration::getFixedAttributesByteSize(const DWARFUnit &U) const; - Any functions that used to take a "const DWARFUnit *U" that would crash if U was NULL now take a "const DWARFUnit &U" and are only called with a valid DWARFUnit Differential Revision: https://reviews.llvm.org/D26567 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@286924 91177308-0d34-0410-b5e6-96231b3b80d8

Switch all DWARF variables for tags, attributes and forms over to use the llvm::dwarf enumerations instead of using raw uint16_t values. This allows easier debugging as users can see the values of the enumerations in the variables view that will show the enumeration string instead of just a number. https://reviews.llvm.org/D26013 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@285309 91177308-0d34-0410-b5e6-96231b3b80d8

In preparation for adding PDB support to LLVM, this moves the DWARF parsing code to its own subdirectory under DebugInfo, and renames LLVMDebugInfo to LLVMDebugInfoDWARF. This is purely a mechanical / build system change.

dsymutil needs access to DWARF specific inforamtion, the small DIContext wrapper isn't sufficient. Other DWARF consumers might want to use it too (I'm looking at you lldb).

This introduces a new library to LLVM: libDebugInfo. It will provide debug information parsing to LLVM. Much of the design and some of the code is taken from the LLDB project. It also contains an llvm-dwarfdump tool that can dump the abbrevs and DIEs from an object file. It can be used to write tests for DWARF input and output easily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139627 91177308-0d34-0410-b5e6-96231b3b80d8
