Chris Lattner deee7a3c0b restrict the && -> & warning to cover a case daniel noted. 
Don't warn about "logically bool" expressions on the RHS,
even if they fold to a constant.

Jakob Stoklund Olesen 8b1bb8cfbd Last COPY conversion. 
llvm-svn: 108387
 2010-07-14 23:58:21 +00:00
Bob Wilson 0b9aafddc5 Remove restriction on NEON alignment values. Some of the NEON ld/st 
instructions use different values (e.g., 2-byte or 4-byte alignment).
Also fix ARMInstPrinter to print these alignments as bits instead of bytes.

 2010-07-14 23:54:43 +00:00
Jakob Stoklund Olesen 9b449d5a92 Use TargetOpcode::COPY instead of X86-native register copy instructions when 
lowering atomics. This will allow those copies to still be coalesced after
TII::isMoveInstr is removed.

llvm-svn: 108385
 2010-07-14 23:50:27 +00:00
Bob Wilson 5d2c1218f1 Remove the entire docs directory from Apple-style builds. 
This fixes a "usr_junk" verification failure when installing into /usr.

Sebastian Redl 85b2a6a430 Add a callback interface that allows interested parties to get notified whenever PCHReader deserializes a type or decl (and possibly other things in the future). Have PCHWriter implement these callbacks as noops and register to receive them if we're chaining PCHs. This will allow PCHWriter to track the IDs of these things, which it needs to write the dependent files. WIP

Bob Wilson 6f4f3612cc Try to get embedded build of llvmCore to pass verification. 
Simplify some things in the process.

Sean Callanan 7618f4ebaf Fixes to the IR generator in the expression parser 
to correctly unfold constant-folded global variables.
Also added code to JIT the expression.  Simple 
expressions are now JIT compiled successfully.

Daniel Dunbar 6f2e839693 CodeGen/ObjC/NeXT: Fix Obj-C message send to match llvm-gcc when choosing 
whether to use objc_msgSend_fpret; the choice is target dependent, not Obj-C ABI
dependent.
 - <rdar://problem/8139758> arm objc _objc_msgSend_fpret bug

llvm-svn: 108379

Owen Anderson 37d91d84af Add instcombine transforms to optimize tests of multiple bits of the same value into a single larger comparison. 
llvm-svn: 108378
 2010-07-14 23:33:51 +00:00
Sebastian Redl 8b41f30064 There is another implementation of PCHReaderListener around. Update it to the new interface.

Douglas Gregor eebe72199e When determining whether an overload set with explicit template 
arguments only resolves to a single specialization, make sure to look
through using declarations. Fixes PR7641.

Benjamin Kramer 8d5609b604 Pass StringRefs by value. 
llvm-svn: 108375
 2010-07-14 23:19:41 +00:00
Douglas Gregor 5f0e252f63 When there are extra or missing template parameter lists in a template 
definition, we're likely going to end up breaking the invariants of
the template system, e.g., that the depths of template parameter lists
match up with the nesting template of the template. So, make sure we
mark such ill-formed declarations as invalid or don't even build them
at all.

Devang Patel 29168baf4b Make it a .ll test case.

 2010-07-14 23:12:52 +00:00
Dan Gohman f10cd5c6cb Make the order in which variables are described in debug information 
independent of the order that isel happens to visit the dbg_declare
intrinsics. This fixes a bug in which the formal arguments were
being printed in reverse order, now that fast isel is going bottom up.

llvm-svn: 108369

Chris Lattner 769aedd523 fix indentation

 2010-07-14 23:04:59 +00:00
Bob Wilson f1a6d7abc3 Remove some broken code to check the DISABLE_EDIS flag (edis is now in the 
DIRS list, so it does no good to filter it from PARALLEL_DIRS), and replace
it with a check to disable building the shared library version of edis when
the flag is set.  Disabling it entirely does not work because MC uses it now.

Dan Gohman 1513217e27 Just use getParent() instead of getModuleFromVal when the value is a Function.

Dan Gohman efb8dbb3f1 Rename WriteConstantInt to WriteConstantInternal, to avoid confusion. 
llvm-svn: 108357
 2010-07-14 20:57:55 +00:00
Sebastian Redl 409183ff7c Increase the max PCH level for declarations to 7. Add a FromPCH flag to types. 
llvm-svn: 108354
 2010-07-14 20:26:45 +00:00
Owen Anderson 2cfe91379b Extend SimplifyCFG's common-destination folding heuristic to allow a single 
"bonus" instruction to be speculatively executed.  Add a heuristic to
ensure we're not tripping up out-of-order execution by checking that this bonus
instruction only uses values that were already guaranteed to be available.

This allows us to eliminate the short circuit in (x&1)&&(x&2).

Daniel Dunbar 9765b9817d Driver: When re'execing clang, use path to the main executable instead of 
looking up Clang in the normal search paths (which may end up finding the wrong
clang).

Fariborz Jahanian 56a9d54de8 Don't error when doing default property synthesis 
and some are already synthesized by user declaration.

Sebastian Redl 75fbb3b5e5 Make PCHReader cope with PCH files containing more than one predefines buffer.

Jim Grosbach a90af1ba38 Improve 64-subtraction of immediates when parts of the immediate can fit 
in the literal field of an instruction. E.g.,
long long foo(long long a) {
  return a - 734439407618LL;
}

Douglas Gregor 9f1570d993 Only filter out names reserved for the implementation (e.g., __blah or 
_Foo) from code-completion results when they come from a system
header.

Dan Gohman 042523340b Delete fast-isel's trivial load optimization; it breaks debugging because 
it can look past points where a debugger might modify user variables.

Duncan Sands 7a68cd094b Rather than using an ifdef on the target to zero out fields, 
just use memset to zero the entire struct.
