llvm-svn: 109443
 2010-07-26 21:33:22 +00:00
Dan Gohman 0eb9c124a7 It's not necessary to call flush() on a raw_ostream immediately prior 
to deleting it.

Dan Gohman c0539d2eb6 Use an export file. Plugins must export llvm::Registry symbols. 
Also, don't link in all the clang libraries statically.

Sebastian Redl ae8cbb7220 Make sure that implicit qualification and derived-to-base conversions of xvalues preserve xvalue-ness. Unfortunately I have no idea how to test this property; there doesn't seem to be a syntactical construct that triggers such a conversion and still allows the distinction between prvalues and xvalues to be made.

Douglas Gregor 67ca40c419 Eliminate the "minimal" and printing parser actions, which only ever 
worked for C anyway. Also kills the -cc1 options -parse-noop and
-parse-print-callbacks.

Benjamin Kramer f5c4b49278 Wrap bit mangling logic for DiagMappings in its own class so it doesn't leak 
into other code. Make it an array instead of a constant-length vector.

llvm-svn: 109379

llvm-svn: 109378
 2010-07-25 18:23:53 +00:00
Douglas Gregor b412e174db Remove the vast majority of the Destroy methods from the AST library, 
since we aren't going to be calling them ever.

Douglas Gregor 5b11d49a7c Make ASTContext always use the BumpPtrAllocator. 
llvm-svn: 109375
 2010-07-25 17:53:33 +00:00
Douglas Gregor f2430ba223 Start removing the use of smart pointers from the Parse/Sema 
interaction, by effectively defaulting to
DISABLE_SMART_POINTERS. We're embracing the model where all AST nodes
are ASTContext-allocated and live as long as the ASTContext lives.

John McCall 268b576b72 Mangle enum constant expressions. Fixes rdar://problem/8204122 
llvm-svn: 109315
 2010-07-24 01:17:35 +00:00
Chris Lattner 938533db60 turn down the logical bitwise confusion warning to not warn 
when the RHS of the ||/&& is ever 0 or 1.  This handles a variety of
creative idioms for "true" used in C programs and fixes many false 
positives at the expense of a few false negatives.  This fixes
rdar://8230351.

Devang Patel 268ad093a7 Untangle filename/dirname confusion. Store constructed strings on the side. Avoid use of Path.makeAbsolute(). 
DW_TAG_compile_unit uses two attributes DW_AT_name and DW_AT_comp_dir. Their expected values are:

$ clang foo.c -g
  DW_AT_name - foo.c
  DW_AT_comp_dir - `pwd`

$ clang one/two/foo.c -g
  DW_AT_name - one/two/foo.c
  DW_AT_comp_dir - `pwd`

$ clang /tmp/one/foo.c -g
  DW_AT_name - /tmp/one/foo.c
  DW_AT_comp_dir - empty

Douglas Gregor f5275a8339 Put a newline at the end of the padded buffers used for the 
precompiled preamble. This will suppress the -pedantic "no newline at
end of file" warning.

llvm-svn: 109301
 2010-07-24 00:42:07 +00:00
Douglas Gregor 6481ef1f9c Once we've built (or reused) a precompiled preamble, create the 
appropriately-padded main file buffer (that has spaces in the extra
"reserved" space) and thread that buffer through to the parsing
function. This still does nothing.

John McCall 2ca705eb13 Support catching Objective C pointers in C++ under the non-fragile NeXT runtime. 
Diagnose attempts to do this under the GNU or fragile NeXT runtimes.

Fariborz Jahanian 72cdffa401 Return type of a setter call caused by 
use of property-dot syntax using 'super' as receiver
is 'void'. This fixes a bug in generating correct
API for setter call. Fixes radar 8203426.

llvm-svn: 109297
 2010-07-24 00:34:08 +00:00
Douglas Gregor 536f091f95 Be careful; even though we had a proper name at the beginning of 
Sema::ActOnDeclarator doesn't mean that the Decl we ended up creating
has a useful name. <rdar://problem/8229910>

llvm-svn: 109296
 2010-07-24 00:10:38 +00:00
Douglas Gregor 4dde74988e Once we've built a precompiled preamble, keep track of the details of 
that preamble (the preamble text, preamble file, reserved main file
size). Check these details when we try to rebuild the precompiled
preamble, and when nothing has changed, re-use the precompiled
preamble.

This code is still very much a WIP, and can't even properly be tested
because we have no way to use the precompiled preamble yet. "Trust me"

Tom Care cba9f517ac Added an path-sensitive unreachable code checker to the experimental analyzer checks. 
- Created a new class to do post-analysis
- Updated several test cases with unreachable code to expect a warning
- Added some general tests

John McCall ad5d61e227 Revise cleanup IR generation to fix a major bug with cleanups (PR7686) 
as well as some significant asymptotic inefficiencies with threading
multiple jumps through deep cleanups.

Devang Patel 28f167699a There is no need to use separate dir name for AT_comp_dir attribute. Using absolute path for filename allows clients to query complete file location info from gdb breakpoints. Save constructed full file name.

Eli Friedman d4c75cddde Fix for PR7694: make sure to pass in a RecordType to CheckBaseClassAccess; 
fixes crashes on both valid and invalid code.  The diagnostic here could
potentially be improved, but it's good enough as-is.

llvm-svn: 109243
 2010-07-23 18:15:17 +00:00
Douglas Gregor 5cc2c8b9c3 Vectors are not integer types, so the type system should not classify 
them as such. Type::is(Signed|Unsigned|)IntegerType() now return false
for vector types, and new functions
has(Signed|Unsigned|)IntegerRepresentation() cover integer types and
vector-of-integer types. This fixes a bunch of latent bugs.

Patch from Anton Yartsev!
