2009-04-18Don't emit name-lookup tables for functions or methods in the PCH filesDouglas Gregor

2009-04-18rewrite the goto scope checking code to be more efficient, simpler,Chris Lattner
produce better diagnostics, and be more correct in ObjC cases (fixing rdar://6803963). An example is that we now diagnose: int test1(int x) { goto L; int a[x]; int b[x]; L: return sizeof a; } with: scope-check.c:15:3: error: illegal goto into protected scope goto L; ^ scope-check.c:17:7: note: scope created by variable length array int b[x]; ^ scope-check.c:16:7: note: scope created by variable length array int a[x]; ^ instead of just saying "invalid jump". An ObjC example is: void test1() { goto L; @try { L: ; } @finally { } } t.m:6:3: error: illegal goto into protected scope goto L; ^ t.m:7:3: note: scope created by @try block @try { ^ There are a whole ton of fixme's for stuff to do, but I believe that this is a monotonic improvement over what we had. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69437 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-18Lazy deserialization of function bodies for PCH files. For the CarbonDouglas Gregor
"Hello, World!", this takes us from deserializing 6469 statements/expressions down to deserializing 1 statement/expression. It only translated into a 1% improvement on the Carbon-prefixed 403.gcc, but (a) it's the right thing to do, and (b) we expect this to matter more once we lazily deserialize identifiers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69407 91177308-0d34-0410-b5e6-96231b3b80d8

from a PCH file. It turns out that "Hello, World!" is bringing in 19% of all of the statements in Carbon.h, so we need to be lazy. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69393 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-17tweak redefinition of a typedef a bit to fix a couple of problems:Chris Lattner
1. We had logic in sema to decide whether or not to emit the error based on manually checking whether in a system header file. 2. we were allowing redefinitions of typedefs in class scope in C++ if in header file. 3. there was no way to force typedef redefinitions to be accepted by the C compiler, which annoys me when stripping linemarkers out of .i files. The fix is to split the C++ class typedef redefinition path from the C path, and change the C path to be a warning that normally maps to error. This causes it to properly be ignored in system headers, etc. and gives us a way to control it. Passing -Wtypedef-redefinition now turns the error into a warning. One behavior change is that we now diagnose cases where you redefine a typedef in your .c file that was defined in a header file. This seems like reasonable behavior, and the diagnostic now indicates that it can be controlled with -Wtypedef-redefinition. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69391 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-17Fix two embarrassing PCH bugs:Douglas Gregor
1) Accidentally used delete [] on an array of statements that was allocated with ASTContext's allocator 2) Deserialization of names with multiple declarations (e.g., a struct and a function) used the wrong mangling constant, causing it to view declaration IDs as Decl*s. 403.gcc builds and links properly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69390 91177308-0d34-0410-b5e6-96231b3b80d8
