2013-01-28Fix the indentation of the first line of preprocessor outputHal Finkel1-1/+5
The -E output from clang did not produce the correct indentation on the first line. This is because MoveToLine returned false, and when this happens, the regular process for producing initial indentation is skipped. Thanks to Eli for suggesting a way to simplify this to a one-line change. llvm-svn: 173657

2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth1-2/+2
uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. llvm-svn: 169237
2012-11-16CPP Output: Do not emit an enter file marker for the main file.Daniel Dunbar1-0/+11
- This diverges from gcc, and confuses tools (like dtrace) which track # line markers as a way to determine which content is in the context of the main file. llvm-svn: 168128
2012-08-29Keep history of macro definitions and #undefsAlexander Kornienko1-2/+6
Summary: Summary: Keep history of macro definitions and #undefs with corresponding source locations, so that we can later find out all macros active in a specified source location. We don't save the history in PCH (no need currently). Memory overhead is about sizeof(void*)*3*<number of macro definitions and #undefs>+<in-memory size of all #undef'd macros> I've run a test on a file composed of 109 .h files from boost 1.49 on x86-64 linux. Stats before this patch: *** Preprocessor Stats: 73222 directives found: 19171 #define. 4345 #undef. #include/#include_next/#import: 5233 source files entered. 27 max include stack depth 19210 #if/#ifndef/#ifdef. 2384 #else/#elif. 6891 #endif. 408 #pragma. 14466 #if/#ifndef#ifdef regions skipped 80023/451669/1270 obj/fn/builtin macros expanded, 85724 on the fast path. 127145 token paste (##) operations performed, 11008 on the fast path.

Preprocessor Memory: 7541687B total BumpPtr: 6066176 Macro Expanded Tokens: 417768 Predefines Buffer: 8135 Macros: 1048576 #pragma push_macro Info: 0 Poison Reasons: 1024 Comment Handlers: 8 In my test increase in memory usage is about 1.7Mb, which is ~28% of initial preprocessor's memory usage and about 0.8% of clang's total VMM allocation. As for CPU overhead, it should only be noticeable when iterating over all macros, and should mostly consist of couple extra dereferences and one comparison per macro + skipping of #undef'd macros. It's less trivial to measure, though, as the preprocessor consumes a very small fraction of compilation time.

2012-03-11Unify naming of LangOptions variable/get function across the Clang stack ↵David Blaikie1-1/+1

2012-02-07Revert my patches which removed Diagnostic.h includes by moving some ↵Benjamin Kramer1-3/+3
operator overloads out of line. This seems to negatively affect compile time onsome ObjC tests (which use a lot of partial diagnostics I assume). I have to come up with a way to keep them inline without including Diagnostic.h everywhere. Now adding a new diagnostic requires a full rebuild of e.g. the static analyzer which doesn't even use those diagnostics. This reverts commit 6496bd10dc3a6d5e3266348f08b6e35f8184bc99.

The previous name was inaccurate as this token in fact appears at the end of every preprocessing directive, not just macro definitions. No functionality change, except for a diagnostic tweak. llvm-svn: 126631

2010-11-19Several PPCallbacks take an SourceLocation + IdentifierInfo, ratherCraig Silverstein1-10/+7
than a Token that holds the same information all in one easy-to-use package. There's no technical reason to prefer the former -- the information comes from a Token originally -- and it's clumsier to use, so I've changed the code to use tokens everywhere. Approved by clattner llvm-svn: 119845

2010-07-13Modify the pragma handlers to accept and use StringRefs instead of ↵Argyrios Kyrtzidis1-3/+3
IdentifierInfos. When loading the PCH, IdentifierInfos that are associated with pragmas cause declarations that use these identifiers to be deserialized (e.g. the "clang" pragma causes the "clang" namespace to be loaded). We can avoid this if we just use StringRefs for the pragmas. As a bonus, since we don't have to create and pass IdentifierInfos, the pragma interfaces get a bit more simplified. llvm-svn: 108237
