r110903 introduced a dependency from Frontend to every library that
declared an Action by introducing Action references that previously
resided in the driver in the file ExecuteCompilerInvocation.cpp.
This patch moves ExecuteCompilerInvocation to a new library named
FrontendTool which is intended to bear these dependencies.

declarator. Here, we can only see a few things (e.g., cvr-qualifiers,
nested name specifiers) and we do not want to provide other non-macro
completions. Previously, we would end up in recovery mode and would
provide a large number of non-relevant completions.

than old data, and (2) keep the remapped files alive until the

nested-name-specifiers. Also includes fixes to the generation of
nested-name-specifier result in the non-cached case; we were producing
lame results for namespaces and namespace aliases, which (1) didn't
always have nested-name-specifiers when we want them, and (2) did not
have the necessary "::" as part of the completion.

the usage type of each declaration result, then compare those types to
the preferred type of the completion. This provides parity in the
priority calculation between the code-completion results produced
directly from Sema and those cached by ASTUnit.
For the standard Cocoa.h (+ others) example, there's a penalty of 3-4
hundredeths of a second when caching the global results (for ~31,000
results), because we need an ASTContext-agnostic representation of
types for the comparison, and therefore we use... strings. Eventually,
we'd like to implement a more efficient ASTContext-agnostic encoding
of types.
llvm-svn: 111165
type class, so that we can adjust priorities appropriately when the
preferred type for the context and the actual type of the completion
are similar.
This gets us one step closer to parity of the cached completion
results with the non-cached completion results.

declarations (in addition to macros). Each kind of declaration maps to
a certain set of completion contexts, and the ASTUnit completion logic
introduces the completion strings for those declarations if the actual
code-completion occurs in one of the contexts where it matters.
There are a few new code-completion-context kinds. Without these,
certain completions (e.g., after "using namespace") would need to
suppress all global completions, which would be unfortunate.
Note that we don't get the priorities right for global completions,
because we don't have enough type information. We'll need a way to
compare types in an ASTContext-agnostic way before this can be
implemented.

when the CXTranslationUnit_CacheCompletionResults option is given to
clang_parseTranslationUnit(). Essentially, we compute code-completion
results for macro definitions after we have parsed the file, then
store an ASTContext-agnostic version of those results (completion
string, cursor kind, priority, and active contexts) in the
ASTUnit. When performing code completion in that ASTUnit, we splice
the macro definition results into the results provided by the actual
code-completion (which has had macros turned off) before libclang gets
those results. We use completion context information to only splice in
those results that make sense for that context.
With a completion involving all of the macros from Cocoa.h and a few other
system libraries (totally ~8500 macro definitions) living in a
precompiled header, we get about a 9% performance improvement from
code completion, since we no longer have to deserialize all of the
macro definitions from the precompiled header.
Note that macro definitions are merely the canary; the cache is
designed to also support other top-level declarations, which should be
a bigger performance win. That optimization will be next.
Note also that there is no mechanism for determining when to throw
away the cache and recompute its contents.

a -cc1 option. The Darwin linker complains about mixed visibility when linking
gcc-built objects with clang-built objects, and the optimization isn't really
that valuable. Platforms with less ornery linkers can feel free to enable this.
