returning a scalar value in a function whose return type is a single-

Eli Friedman 2d9c47ea6c PR9615: make sure we destroy any temporaries returned by operator->. 
I'm pretty sure this is the right fix, but I would appreciate it if someone
else would double-check.

Eli Friedman b85c0caf7d Attempt to fix breakage from r128782 reported by Francois Pichet on 
llvm-commits.  (Not sure why it only breaks on Windows; maybe it has
something to do with the iterator representation...)

Eric Christopher ee066fc4f3 Assorted bugfixes in object file handling: 
- Adds support for sniffing PE/COFF files on win32 (.exe and .dll)
   which are COFF files that have an MS-DOS compatibility stub on
   the front of them.

 - Fixes a bug in the COFFObjectFile's support for the Microsoft COFF
   extension for long symbol names, wherein it was attempting to parse
   the leading '/' in an extended symbol name reference as part of the
   integer offset.

 - Fixes bugs in COFFObjectFile and ELFObjectFile wherein section
   and symbol iterators were being returned with uninitialized bytes;
   the type DataRefImpl is a union between 2 32-bit words (d.a and d.b)
   and a single intptr_t word (p). Only p was being initialized, so in
   32-bit builds the result would be iterators with random upper 32-bit
   words in their DataRefImpls. This caused random failures when
   seeking around in object files.

Richard Smith 13f68cf53e clang has had full and tested support for C++0x trailing-return-type and auto type deduction since r126166. Update the website to reflect this, and add a __has_feature test. 
trailing-return-type codegen is not tested yet (name mangling in particular).

Lenny Maiorani fca2e9618a Refactoring the security checker a little bit so that each CallExpr check doesn't get called for each CallExpr. Instead it does a switch and only runs the check for the proper identifier. Slight speed improvement (probably significant on very large ASTs), and should make it easier and more clear to add more checks for other CallExpr's later.

Eli Friedman 17bf4922c9 PR9446: RecursivelyDeleteTriviallyDeadInstructions can delete the instruction 
after the given instruction; make sure to handle that case correctly.
(It's difficult to trigger; the included testcase involves a dead 
block, but I don't think that's a requirement.) 

While I'm here, get rid of the unnecessary warning about
SimplifyInstructionsInBlock, since it should work correctly as far as I know.

Eli Friedman 8baa2c7ad9 Don't assume something which might be a constant expression is an instruction. 
Based on PR9429, but no testcase because I can't figure out how to trigger it
anymore given other changes to the relevant code.

Benjamin Kramer 50a281a871 While SimplifyDemandedBits constant folds this, we can't rely on it here. 
It's possible to craft an input that hits the recursion limits in a way
that SimplifyDemandedBits doesn't simplify the icmp but ComputeMaskedBits
can infer which bits are zero.

No test case as it depends on too many other things. Fixes PR9609.

Oscar Fuentes f2ab92833a Handle changing of LLVM_ENABLE_FFI. 
If someone first configure build with LLVM_ENABLE_FFI=1 and then turn it
off, the build will fail in lib/ExecutionEngine/Interpreter because
Interpreter will try still to #include <ffi/ffi.h>, but there are no
include_directories(${FFI_INCLUDE_DIR}) now.

This patch unset()'s HAVE_FFI_H and HAVE_FFI_FFI_H from cache file if
LLVM_ENABLE_FFI=0. This forces CMake to update config.h.

Chandler Carruth f20ec92331 Apply a bug-fix patch from Marcin Kowalczyk to the source locations for 
a couple of operator overloads which form interesting expressions in the
AST.

I added test cases for both bugs with the c-index-test's token
annotation feature. Also, thanks to John McCall for confirming that this
is the correct solution.

Jakob Stoklund Olesen ca26e0acbb Use InterferenceCache in RegAllocGreedy. 
llvm-svn: 128765
 2011-04-02 06:03:38 +00:00
Jakob Stoklund Olesen 91cbcaf957 Add an InterferenceCache class for caching per-block interference ranges. 
When the greedy register allocator is splitting multiple global live ranges, it
tends to look at the same interference data many times. The InterferenceCache
class caches queries for unaltered LiveIntervalUnions.

 2011-04-02 06:03:35 +00:00
Jakob Stoklund Olesen 36171288ce Use basic block numbers as indexes when mapping slot index ranges. 
This is more compact and faster than using DenseMap.

Cameron Zwarich 6fe5c29430 Do some peephole optimizations to remove pointless VMOVs from Neon to integer 
registers that arise from argument shuffling with the soft float ABI. These
instructions are particularly slow on Cortex A8. This fixes one half of
<rdar://problem/8674845>.

Cameron Zwarich 8c7bbc09e2 Add a RemoveFromWorklist method to DCI. This is needed to do some complicated 
transformations in target-specific DAG combines without causing DAGCombiner to
delete the same node twice. If you know of a better way to avoid this (see my
next patch for an example), please let me know.
