* Lazy loading of builtins for precompiled headers.Douglas Gregor2009-04-221-8/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PCH files now contain complete information about builtins, including any declarations that have been synthesized as part of building the PCH file. When using a PCH file, we do not initialize builtins at all; when needed, they'll be found in the PCH file. This optimization translations into a 9% speedup for "Hello, World!" with Carbon.h as a prefix header and roughly a 5% speedup for 403.gcc with its prefix header. We're also reading less of the PCH file for "Hello, World!": *** PCH Statistics: 286/20693 types read (1.382110%) 1630/59230 declarations read (2.751984%) 764/44914 identifiers read (1.701029%) 1/32954 statements read (0.003035%) 5/6187 macros read (0.080815%) down from *** PCH Statistics: 411/20693 types read (1.986179%) 2553/59230 declarations read (4.310316%) 1093/44646 identifiers read (2.448148%) 1/32954 statements read (0.003035%) 21/6187 macros read (0.339421%) llvm-svn: 69815

* Lazy deserialization of macro definitions for precompiled headers.Douglas Gregor2009-04-211-10/+23
| | | | | | | | | | | | | | | This optimization improves performance on the Carbon-prefixed "Hello, World!" example by 57%. For reference, we're now about 2.25x faster than GCC PCH. We're also pulling in far less of the PCH file: *** PCH Statistics: 411/20693 types read (1.986179%) 2553/59230 declarations read (4.310316%) 1093/44646 identifiers read (2.448148%) 1/32954 statements read (0.003035%) 21/6187 macros read (0.339421%) llvm-svn: 69755
* Don't bother writing a visible-declarations record for the translationDouglas Gregor2009-04-211-3/+5
| | | | | | | unit into the PCH file, since we won't be performing name lookup into it anyway. Reduces the size of the Carbon.h PCH file by ~200k. llvm-svn: 69739
* Lazy deserialization of the declaration chains associated withDouglas Gregor2009-04-211-13/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | identifiers from a precompiled header. This patch changes the primary name lookup method for entities within a precompiled header. Previously, we would load all of the names of declarations at translation unit scope into a large DenseMap (inside the TranslationUnitDecl's DeclContext), and then perform a special "last resort" lookup into this DeclContext when we knew there was a PCH file (see Sema::LookupName). Now, when we see an identifier named for the first time, we load all of the declarations with that name that are visible from the translation unit into the IdentifierInfo's chain of declarations. Thus, the explicit "look into the translation unit's DeclContext" code is gone, and Sema effectively uses the same IdentifierInfo-based name lookup mechanism whether we are using a PCH file or not. This approach should help PCH scale with the size of the input program rather than the size of the PCH file. The "Hello, World!" application with Carbon.h as a PCH file now loads 20% of the identifiers in the PCH file rather than 85% of the identifiers. 90% of the 20% of identifiers loaded are actually loaded when we deserialize the preprocessor state. The next step is to make the preprocessor load macros lazily, which should drastically reduce the number of types, declarations, and identifiers loaded for "Hello, World". llvm-svn: 69737

* Write the identifier table into the PCH file as an on-disk hash tableDouglas Gregor2009-04-201-18/+98
| | | | | | | | | | | that also includes the contents of the IdentifierInfo itself (the various fields and flags, along with the chain of identifiers visible at the top level that have that name). We don't make any use of the hash table yet, except that our identifier ID -> string mapping points into the hash table now. llvm-svn: 69625
