[llvm-readobj] Change -long-option to --long-option in tests. NFC We use both -long-option and --long-option in tests. Switch to --long-option for consistency. In the "llvm-readelf" mode, -long-option is discouraged as it conflicts with grouped short options and it is not accepted by GNU readelf. While updating the tests, change llvm-readobj -s to llvm-readobj -S to reduce confusion ("s" is --section-headers in llvm-readobj but --symbols in llvm-readelf). llvm-svn: 359649

[codeview] Optimize the size of defranges with gaps For small, discontiguous local variable regions, CodeView can use a single defrange record with a gap, rather than having two defrange records. I expect that this optimization will only have a minor impact on debug info size. llvm-svn: 281664

# This tries to test defrange gap edge cases.
[codeview] Change readobj symbol dumping format Avoid duplicating DictScope with hand-written names everywhere. Print the S_-prefixed symbol kind for every record. This should make it easier to search for certain kinds of records when debugging PDB linking. llvm-svn: 307732

[codeview] Use push_macro to avoid conflicts instead of a prefix Summary: This prefix was added in r333421, and it changed our dumper output to say things like "CVRegEAX" instead of just "EAX". That's a functional change that I'd rather avoid. I tested GCC, Clang, and MSVC, and all of them support #pragma push_macro. They don't issue warnings whem the macro is not defined either. I don't have a Mac so I can't test the real termios.h header, but I looked at the termios.h sources online and looked for other conflicts. I saw only the CR* macros, so those are the ones we work around.
