* This reworks some of the Diagnostic interfaces a bit to change how diagnosticsChris Lattner2008-11-182-9/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | are formed. In particular, a diagnostic with all its strings and ranges is now packaged up and sent to DiagnosticClients as a DiagnosticInfo instead of as a ton of random stuff. This has the benefit of simplifying the interface, making it more extensible, and allowing us to do more checking for things like access past the end of the various arrays passed in. In addition to introducing DiagnosticInfo, this also substantially changes how Diagnostic::Report works. Instead of being passed in all of the info required to issue a diagnostic, Report now takes only the required info (a location and ID) and returns a fresh DiagnosticInfo *by value*. The caller is then free to stuff strings and ranges into the DiagnosticInfo with the << operator. When the dtor runs on the DiagnosticInfo object (which should happen at the end of the statement), the diagnostic is actually emitted with all of the accumulated information. This is a somewhat tricky dance, but it means that the accumulated DiagnosticInfo is allowed to keep pointers to other expression temporaries without those pointers getting invalidated. This is just the minimal change to get this stuff working, but this will allow us to eliminate the zillions of variant "Diag" methods scattered throughout (e.g.) sema. For example, instead of calling: Diag(BuiltinLoc, diag::err_overload_no_match, typeNames, SourceRange(BuiltinLoc, RParenLoc)); We will soon be able to just do: Diag(BuiltinLoc, diag::err_overload_no_match) << typeNames << SourceRange(BuiltinLoc, RParenLoc)); This scales better to support arbitrary types being passed in (not just strings) in a type-safe way. Go operator overloading?! llvm-svn: 59502
* Change the diagnostics interface to take an array of pointers to Chris Lattner2008-11-181-3/+4
| | | | | | | | strings instead of array of strings. This reduces string copying in some not-very-important cases, but paves the way for future improvements. llvm-svn: 59494

* Add a new expression node, CXXOperatorCallExpr, which expresses aDouglas Gregor2008-11-141-1/+3
| | | | | | | | | | | | | | | | | | | function call created in response to the use of operator syntax that resolves to an overloaded operator in C++, e.g., "str1 + str2" that resolves to std::operator+(str1, str2)". We now build a CXXOperatorCallExpr in C++ when we pick an overloaded operator. (But only for binary operators, where we actually implement overloading) I decided *not* to refactor the current CallExpr to make it abstract (with FunctionCallExpr and CXXOperatorCallExpr as derived classes). Doing so would allow us to make CXXOperatorCallExpr a little bit smaller, at the cost of making the argument and callee accessors virtual. We won't know if this is going to be a win until we can parse lots of C++ code to determine how much memory we'll save by making this change vs. the performance penalty due to the extra virtual calls. llvm-svn: 59306
* Easy IRgen improvement for bitfields, don't emit x >> 0.Daniel Dunbar2008-11-131-2/+3
| | | | | | | - Logic such as this quite possibly should be optional builder behavior. llvm-svn: 59213
* Supply finished flag to EmitBlock for common statements which useDaniel Dunbar2008-11-131-9/+6
| | | | | | | | | | landing pads. - Primarily a cleanliness issue instead of a performance issue (this eliminates all blocks w/o predecessors on 176.gcc/expr.c), but this also allows subsequent code to recognize it is unreachable and potentially avoid IRgen. llvm-svn: 59211
* Normalize many BasicBlock names.Daniel Dunbar2008-11-136-24/+24
| | | | | | | | | | - Use dotted notation for blocks related to a particular statement type. - Use .end for landing pads. No functionality change in NDEBUG mode. :) llvm-svn: 59210
* Add IsFinished arg to EmitBlock.Daniel Dunbar2008-11-132-2/+13
| | | | | | | | | | - Indicates that caller is done with the block and it can be dropped if it has no predecessors. Useful for callers who need to make landing pads but which may not be reached. No functionality change. llvm-svn: 59207
* For if blocks with no else, name the join block ifend instead of theDaniel Dunbar2008-11-131-6/+5
| | | | | | | | more confusing ifelse. Use dotted names for if blocks (if.then vs ifthen). llvm-svn: 59201

* Rename ?: operator blocks to cond.true and cond.false (I don't knowDaniel Dunbar2008-11-121-2/+2

* Lower ?: into select when the selected values are cheap and side-effect-free.Chris Lattner2008-11-121-0/+37

* emit better codegen for ||/&&, shrinking expr.ll by another 240 lines.Chris Lattner2008-11-121-19/+31
