Douglas Gregor 2f6358b100 Teach c-index-test to reparse the source file a few times when testing 
clang_getCursor() via -cursor-at=??? and CINDEXTEST_EDITING is set in
the environment. This mirrors how we test code completion and
source-loading in the presence of this environment variable.

Douglas Gregor 936a5b44ee When loading a precompiled preamble, use the file ID of the 
precompiled preamble as the "main" source file's file ID within the
source manager. This makes compiling with a precompiled preamble
produce the same source locations as when compiling without the
precompiled preamble; prior to this change, we ended up with different
file IDs for source locations within the precompiled preamble
vs. those after the precompiled preamble, even for entities (e.g.,
preprocessing entities) in the same file.

Nico Weber ebd45a004d Fix bug in r120299 spotted by dgregor.

Nick Lewycky 2965d3e3cd Make @llvm.invariant.start not be readonly, so that it has side-effects. This 
unbreaks test/Transforms/InstCombine/invariant.ll which was broken by r120382.
This is a fix-forward to do what I think Chris intended.

Jim Ingham f48169bb4f Moved the code in ClangUserExpression that set up & ran the thread plan with timeouts, and restarting with all threads into a utility function in Process. This required a bunch of renaming. 
Added a ThreadPlanCallUserExpression that differs from ThreadPlanCallFunction in that it holds onto a shared pointer to its ClangUserExpression so that can't go away before the thread plan is done using it.

Fixed the stop message when you hit a breakpoint while running a user expression so it is more obvious what has happened.

Jakob Stoklund Olesen d4900a644c Stub out a new LiveDebugVariables pass. 
This analysis is going to run immediately after LiveIntervals. It will stay
alive during register allocation and keep track of user variables mentioned in
DBG_VALUE instructions.

When the register allocator is moving values between registers and the stack, it
is very hard to keep track of DBG_VALUE instructions. We usually get it wrong.
This analysis maintains a data structure that makes it easy to update DBG_VALUE
instructions.

Chris Lattner b438ef236c remove the pointless check of MemoryUseIntrinsic from 
is trivially dead, since these have side effects.  This makes the
(misnamed) MemoryUseIntrinsic class dead, so remove it.

Chris Lattner 9d179d911d clean up handling of 'free', detangling it from everything else. 
It can be seriously improved, but at least now it isn't intertwined
with the other logic.

llvm-svn: 120377
 2010-11-30 01:28:33 +00:00
Nick Lewycky c4f482b1b7 Add a default clause to avoid this GCC warning:

Chris Lattner 43e3a98675 clean up DSE tests, removing some poorly reduced and useless old test, 
merging more into other larger .ll files, filecheckizing along the way.

Chris Lattner 90c4947df7 enhance basicaa to return "Mod" for a memcpy call when the 
queried location doesn't overlap the source, and add a testcase.

llvm-svn: 120370
 2010-11-30 00:43:16 +00:00
Bill Wendling 62718de2b9 Add correct encoding for "bl __aeabi_read_tp". However, the asm matcher isn't 
able to match this yet.

llvm-svn: 120369
 2010-11-30 00:34:08 +00:00
Chris Lattner 9a146372b5 Teach basicaa that memset's modref set is at worst "mod" and never 
contains "ref".

Enhance DSE to use a modref query instead of a store-specific hack
to generalize the "ignore may-alias stores" optimization to handle
memset and memcpy.

llvm-svn: 120368

Sean Callanan 348b5897f9 Added a feature where registers can be referred to 
using special $-variables from expressions.

(lldb) expr $rip

These variables are available for reading and
writing.

Jim Grosbach 027bd47e3e Rename BX/BRIND/etc patterns to clarify which is actually the BX instruction 
and which are pseudos.

llvm-svn: 120366
 2010-11-30 00:24:05 +00:00
Bill Wendling 85a8a72d85 Add some encoding for the adr instruction. Labels still need to be finished. 
llvm-svn: 120365

Owen Anderson e22c7322b8 Correct Thumb2 encodings for a much wider range of loads and stores. 
llvm-svn: 120364
 2010-11-30 00:14:31 +00:00
Chris Lattner c3c754f750 my previous patch would cause us to start deleting some volatile 
stores, fix and add a testcase.

llvm-svn: 120363
 2010-11-30 00:12:39 +00:00
Jim Grosbach 49408cef39 Make a few more ARM pseudo instructions actually use the PseudoInst base class.

Chris Lattner d4f1090948 two changes to DSE that shouldn't affect anything: 
1. Don't bother trying to optimize:

lifetime.end(ptr)
store(ptr)

as it is undefined, and therefore shouldn't exist.

2. Move the 'storing a loaded pointer' xform up, simplifying
  the may-aliased store code.

Bob Wilson 318ce7cb3f Fix the encoding of VLD4-dup alignment. 
The only reasonable way I could find to do this is to provide an alternate
version of the addrmode6 operand with a different encoding function.  Use it
for all the VLD-dup instructions for the sake of consistency.

llvm-svn: 120358
 2010-11-30 00:00:42 +00:00
Bob Wilson 0b27b68164 Rename VLDnDUP instructions with double-spaced registers 
in an attempt to make things a little more consistent.

llvm-svn: 120357
 2010-11-30 00:00:38 +00:00
Bob Wilson 431ac4ef50 Add support for NEON VLD3-dup instructions. 
The encoding for alignment in VLD4-dup instructions is still a work in progress.
