Chris Lattner ff9fbcaa8a if we die in IR generation of a compound statement, include 
it in the stack trace, giving us stuff like:

Stack dump:
0.	Program arguments: clang t.c -emit-llvm 
1.	<eof> parser at end of file
2.	t.c:1:5: LLVM IR generation of declaration 'a'
3.	t.c:1:9: LLVM IR generation of compound statement ('{}')
4.	t.c:2:3: LLVM IR generation of compound statement ('{}')
Abort

Chris Lattner eae6cb6154 rename PrettyStackTraceDecl -> PrettyStackTraceActionsDecl. 
Introduce a new PrettyStackTraceDecl.
Use it to add the top level LLVM IR generation stuff in 
Backend.cpp to stack traces.  We now get crashes like:

Stack dump:
0.	Program arguments: clang t.c -emit-llvm 
1.	<eof> parser at end of file
2.	t.c:1:5: LLVM IR generation of declaration 'a'
Abort

for IR generation crashes.

Chris Lattner bcfe4f7b7b When the parser is live, print out the location and spelling of its current token. 
For example:

Stack dump:
0.	Program arguments: clang t.cpp 
1.	t.cpp:4:8: current parser token: ';'
2.	t.cpp:3:1: parsing struct/union/class body 'x'
Abort

It is weird that the parser is always "underneath" any parse context 
actions, but the parser is created first.

Owen Anderson ad503987a8 Be more careful about choosing restore points when doing restore folding. This fixes some subtle miscompilations.

Chris Lattner 8d0fe8cd90 Daniel wanted the stack printed upside down. Perhaps he 
feels a kinship to machine stacks that grow down.  Now we get
stuff like this:

Stack dump:
0.	Program arguments: clang clang_crash_Iw2Osj.mi 
1.	/Developer/SDKs/MacOSX10.5.sdk/usr/lib/gcc/i686-apple-darwin9/4.0.1/include/xmmintrin.h:624:1: parsing function body '_mm_cvtpi16_ps'
2.	/Developer/SDKs/MacOSX10.5.sdk/usr/lib/gcc/i686-apple-darwin9/4.0.1/include/xmmintrin.h:624:1: in compound statement ('{}')

Nate Begeman 359df7420f When allocating stubs, keep track of which Functions are referencing the stub. 
This invalidates the stubs in the resolver map when they are no longer referenced,
and should the JIT memory manager ever pick up a deallocateStub interface, the
JIT could reclaim the memory for unused stubs as well.

Eli Friedman cecc21d2f6 Make IRGen compatible with declaring a function with incomplete 
return/argument types.  (The generated IR isn't ideal, but we can't 
really do better in general.)

Eli Friedman 22fcc24b30 Initial implementation of CodeGen for incomplete function types; fixes 
PR3688.  (The FIXME is a rather big performance issue, but it only 
affects code using this feature, which is relatively rare.)

Chris Lattner 477f990ac5 Include struct context info for parser/sema crashes. This 
gives us:

Stack dump:
0.	using-directive.cpp:26:16: in compound statement ('{}')
1.	using-directive.cpp:26:16: parsing function body 'A::K1::foo'
2.	using-directive.cpp:25:3: parsing struct/union/class body 'A::K1'
3.	using-directive.cpp:5:1: parsing namespace 'A'
4.	clang using-directive.cpp 
Abort

for code like:

namespace A {
...
  class K1 {
    void foo() { <<crash>>

llvm-svn: 66124
 2009-03-05 02:25:03 +00:00
Chris Lattner e332b82320 Include namespace contexts in the virtual stack trace, so we get stuff 
like this:

Stack dump:
0.	using-directive.cpp:9:14: in compound statement ('{}')
1.	using-directive.cpp:9:14: parsing function body 'A::B::f'
2.	using-directive.cpp:7:3: parsing namespace 'A::B'
3.	using-directive.cpp:5:1: parsing namespace 'A'
4.	clang using-directive.cpp 
Abort

for testcase like like:

namespace A {
  short i;
  namespace B {
    long i;
    void f() { <<crash>>

Chris Lattner e268b406ba include objc method decl contexts in stack trace of crash, e.g.:

2.	clang message.m

locations that are the current tok loc.  Note that inline C++ methods
