2013-01-30[analyzer] Make shallow mode more shallow.Anna Zaks
Redefine the shallow mode to inline all functions for which we have a definite definition (ipa=inlining). However, only inline functions that are up to 4 basic blocks large and cut the max exploded nodes generated per top level function in half. This makes shallow faster and allows us to keep inlining small functions. For example, we would keep inlining wrapper functions and constructors/destructors. With the new shallow, it takes 104s to analyze sqlite3, whereas the deep mode is 658s and previous shallow is 209s. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173958 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-30[analyzer] Use analyzer config for max-inlinable-size option.Anna Zaks

2013-01-30Don't warn about Unicode characters in -E mode.Jordan Rose
People use the C preprocessor for things other than C files. Some of them have Unicode characters. We shouldn't warn about Unicode characters appearing outside of identifiers in this case. There's not currently a way for the preprocessor to tell if it's in -E mode, so I added a new flag, derived from the PreprocessorOutputOptions. This is only used by the Unicode warnings for now, but could conceivably be used by other warnings or even behavioral differences later. <rdar://problem/13107323> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173881 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-30[Frontend] Add an ExternCSystem include entry group.Daniel Dunbar
- The only group where it makes sense for the "ExternC" bit is System, so this simplifies having to have the extra isCXXAware (or ImplicitExternC, depending on what code you talk to) bit caried around. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173859 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-29[Frontend] Make the include dir group independent from the "use sysroot" bit.Daniel Dunbar
- This slightly decouples the path handling, since before the group sometimes dominated the "use sysroot" bit, but it was still passed in via the API. - No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173855 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-29[ubsan] Implement the -fcatch-undefined-behavior flag using a trappingChad Rosier
implementation; this is much more inline with the original implementation (i.e., pre-ubsan) and does not require run-time library support. The trapping implementation can be invoked using either '-fcatch-undefined-behavior' or '-fsanitize=undefined-trap -fsanitize-undefined-trap-on-error', with the latter being preferred. Eventually, the -fcatch-undefined-behavior' flag will be removed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173848 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-28Enable the global module index by default. Introduce theDouglas Gregor
-fno-modules-global-index -cc1 option to allow one to disable the index for performance testing purposes, but with a 10% win in -fsyntax-only time, there is no reason a user would do this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173707 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-24[analyzer] Replace "-analyzer-ipa" with "-analyzer-config ipa".Anna Zaks
The idea is to eventually place all analyzer options under "analyzer-config". In addition, this lays the ground for introduction of a high-level analyzer mode option, which will influence the default setting for IPAMode. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173385 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-23Implement the writer side of the global module index. Douglas Gregor
The global module index is a "global" index for all of the module files within a particular subdirectory in the module cache, which keeps track of all of the "interesting" identifiers and selectors known in each of the module files. One can perform a fast lookup in the index to determine which module files will have more information about entities with a particular name/selector. This information can help eliminate redundant lookups into module files (a serious performance problem) and help with creating auto-import/auto-include Fix-Its. The global module index is created or updated at the end of a translation unit that has triggered a (re)build of a module by scraping all of the .pcm files out of the module cache subdirectory, so it catches everything. As with module rebuilds, we use the file system's atomicity to synchronize. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173301 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth
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.
