Replace the -code-completion-dump option with -code-completion-at=filename:line:column which performs code completion at the specified location by truncating the file at that position and enabling code completion. This approach makes it possible to run multiple tests from a single test file, and gives a more natural command-line interface. llvm-svn: 82571

// Note: the run lines follow their respective tests, since line/column
// matter in this test.
Implement code completion within a function call, triggered after the opening parentheses and after each comma. We gather the set of visible overloaded functions, perform "partial" overloading based on the set of arguments that we have thus far, and return the still-viable results sorted by the likelihood that they will be the best candidate. Most of the changes in this patch are a refactoring of the overloading routines for a function call, since we needed to separate out the notion of building an overload set (common to code-completion and normal semantic analysis) and then what to do with that overload set. As part of this change, I've pushed explicit template arguments into a few more subroutines. There is still much more work to do in this area. Function templates won't be handled well (unless we happen to deduce all of the template arguments before we hit the completion point), nor will overloaded function-call operators or calls to member functions. llvm-svn: 82549

void f(float x, float y);
void f(int i, int j, int k);
struct X { };
void f(X);
namespace N {
struct Y {
Y(int = 0);
operator int() const;
};
Separate the code-completion results for call completion from the results for other, textual completion. For call completion, we now produce enough information to show the function call argument that we are currently on. llvm-svn: 82592

Fix FileCheck --check-prefix lines. Various tests had sprung up over the years which had --check-prefix=ABC on the RUN line, but "CHECK-ABC:" later on. This happened to work before, but was strictly incorrect. FileCheck is getting stricter soon though. Patch by Ron Ofir. llvm-svn: 188174

// RUN: %clang_cc1 -fsyntax-only -code-completion-patterns -code-completion-at=%s:19:9 %s -o - | FileCheck -check-prefix=CHECK-CC1 %s
Make -code-completion-patterns only cover multi-line code completions. Plus, tweak a few completion patterns to better reflect the language grammar. llvm-svn: 104905

When pretty-printing tag types, only print the tag if we're in C (and therefore not creating ElaboratedTypes, which are still pretty-printed with the written tag). Most of these testcase changes were done by script, so don't feel too sorry for my fingers. llvm-svn: 98149

// CHECK-CC1: f(N::Y y, <#int ZZ#>)
When code-completion after a "," is building an overload set, note that there is one more argument (the one following the comma) and make the candidate non-viable if the function cannot accept any argument in that position. llvm-svn: 82625
