Jim Grosbach 25749ad5c2 add cmd line option to leave dbgvalues in during post-RA sceduling. Useful 
while debugging what's mishandled about them in the post-RA pass.

Douglas Gregor fa8b4955bb When a failed dynamic_cast<T&> (which is an lvalue) results in a 
throw, it should use invoke when needed. The fixes the
Boost.Statechrt failures that motivated PR7132, but there are a few
side issues to tackle as well.

Bill Wendling 95f6ebcb37 Rename "HasCalls" in MachineFrameInfo to "AdjustsStack" to better describe what 
the variable actually tracks.

N.B., several back-ends are using "HasCalls" as being synonymous for something
that adjusts the stack. This isn't 100% correct and should be looked into.

Dan Gohman 35dd005d22 Lowering of atomic instructions can result in operands being 
used more than once. If ISel had put a kill flag on one of them,
it's not valid to transfer the kill flag to each new instance.

Devang Patel e0a94bfe9f Add support to preserve type info for the variables that are removed by the optimizer.

Jakob Stoklund Olesen 670492c8ee When verifying two-address instructions, check the following: 
- Kill is implicit when use and def registers are identical.
- Only virtual registers can differ.

Add a -verify-fast-regalloc to run the verifier before the fast allocator.

Kevin Enderby 7bc111f5a9 Fix so "int3" is correctly accepted, added "into" and fixed "int" with an 
argument, like "int $4", to not get an Assertion error.

Daniel Dunbar 2493ddfe42 MC/Mach-O/x86_64: Darwin's special "signed_N" relocation types should only be 
used to replace a normal relocation, not a reference to a GOT entry.

Fariborz Jahanian bdb1b0d6cb Implement new default property synthesis rules. Essentially, no longer 
user directive is needed to force a property implementation.
It is decided based on those propeties which are declared in
the class (or in its protocols) but not those which must be
default implemented by one of its super classes. Implements radar 7923851.

Jakob Stoklund Olesen 4d5c1061e3 Simplify the handling of physreg defs and uses in RegAllocFast. 
This adds extra security against using clobbered physregs, and it adds kill
markers to physreg uses.

Chris Lattner ff895c140c Improve error recovery in C/ObjC when the first argument of a function 
declarator is incorrect.  Not being a typename causes the parser to 
dive down into the K&R identifier list handling stuff, which is almost
never the right thing to do.

Before:

r.c:3:17: error: expected ')'
void bar(intptr y);
                ^
r.c:3:9: note: to match this '('
void bar(intptr y);
        ^
r.c:3:10: error: a parameter list without types is only allowed in a function definition
void bar(intptr y);
         ^

After:

r.c:3:10: error: unknown type name 'intptr'; did you mean 'intptr_t'?
void bar(intptr y);
         ^~~~~~
         intptr_t
r.c:1:13: note: 'intptr_t' declared here
typedef int intptr_t;
            ^

This fixes rdar://7980651 - poor recovery for bad type in the first arg of a C function

Providing linkage name for function static variable confuses gdb, so don't do that.

Daniel Dunbar 4707cef758 Revert r103770, "Added basic source locations to Elaborated and DependentName 
types.", it is breaking Clang bootstrap.

Dan Gohman 8d1bc79327 Use regular PassManager instead of FunctionPassManager in opt, since it 
isn't doing lazy streaming. This also fixes a missing doFinalization call.

 2010-05-14 15:36:54 +00:00
Dan Gohman 1603b2e457 Use PassManagerBase, to give clients the option of using either 
FunctionPassManager or regular PassManager.

Daniel Dunbar 148e876ac2 XFAIL the test I added with vg_leak, apparently it is the first and only llc 
-filetype=obj test, and -filetype=obj leaks a few objects. Added a FIXME, we
need to sort out the ownership model for the various MC objects.

Evan Cheng 3e51388e6a Get rid of the bit twiddling to read / set OpActions and ValueTypeActions. The small saving in memory isn't worth the increase in runtime and code complexity in my opinion.

scopes during unqualified name lookup that has fallen out to namespace
scope. Fixes PR7133.
