[bpf] attempt to fix big-endian bots attempt to fix big-endian bots failing on new dwarfdump test Signed-off-by: Alexei Starovoitov <ast@kernel.org> llvm-svn: 287522

llvm-dwarfdump: Replace -debug-dump=sect option with individual options. As discussed on llvm-dev in http://lists.llvm.org/pipermail/llvm-dev/2017-September/117301.html this changes the command line interface of llvm-dwarfdump to match the one used by the dwarfdump utility shipping on macOS. In addition to being shorter to type this format also has the advantage of allowing more than one section to be specified at the same time. In a nutshell, with this change $ llvm-dwarfdump --debug-dump=info $ llvm-dwarfdump --debug-dump=apple-objc becomes $ dwarfdump --debug-info --apple-objc Differential Revision: https://reviews.llvm.org/D37714 llvm-svn: 312970

Renumber testcase metadata nodes after r290153. This patch renumbers the metadata nodes in debug info testcases after https://reviews.llvm.org/D26769. This is a separate patch because it causes so much churn. This was implemented with a python script that pipes the testcases through llvm-as - | llvm-dis - and then goes through the original and new output side-by side to insert all comments at a close-enough location.

Canonicalize the representation of empty an expression in DIGlobalVariableExpression This change simplifies code that has to deal with DIGlobalVariableExpression and mirrors how we treat DIExpressions in debug info intrinsics. Before this change there were two ways of representing empty expressions on globals, a nullptr and an empty !DIExpression(). If someone needs to upgrade out-of-tree testcases: perl -pi -e 's/(!DIGlobalVariableExpression\(var: ![0-9]*)\)/\1, expr: !DIExpression())/g' <MYTEST.ll> will catch 95%. llvm-svn: 312144

[DebugInfo] Support DWARF v5 source code embedding extension In DWARF v5 the Line Number Program Header is extensible, allowing values with new content types. In this extension a content type is added, DW_LNCT_LLVM_source, which contains the embedded source code of the file. Add new optional attribute for !DIFile IR metadata called source which contains source text. Use this to output the source to the DWARF line table of code objects. Analogously extend METADATA_FILE in Bitcode and .file directive in ASM to support optional source. Teach llvm-dwarfdump and llvm-objdump about the new values. Update the output format of llvm-dwarfdump to make room for the new attribute on file_names entries, and support embedded sources for the -source option in llvm-objdump.
