Add support for generating dwarf debugging info with assembly files run through the 'C' preprocessor. That is pick up the file name and line numbers from the cpp hash file line comments for the dwarf file and line numbers tables. rdar://9275556 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167237 91177308-0d34-0410-b5e6-96231b3b80d8

Now that llvm-dwarfdump supports flags to specify which DWARF section to dump, use them in tests that run llvm-dwarfdump. This is in order to make tests as specific as possible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173498 91177308-0d34-0410-b5e6-96231b3b80d8

DebugInfo: Improve reuse of file table entries in asm debug info The previous deduping strategy was woefully inadequate - it only considered the most recent file used and avoided emitting a duplicate in that case - never considering the a/b/a scenario. It was also lacking when it came to directory paths as the previous filename would never match the current if the filename had been split into file and directory components. This change builds caching functionality into the line table at the lowest level in an optional form (a file number of 0 indicates that one should be chosen and returned) and will eventually be reused by the normal source level debugging DWARF emission. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204027 91177308-0d34-0410-b5e6-96231b3b80d8

Support DWARF discriminators in object streamer. Summary: This adds support for emitting DWARF path discriminator values in the object streamer. It also changes the DWARF dumper to show discriminator values in the line table output.
