Jim Grosbach 56f471726c Clean up LEApcrel instuction(s) a bit. It's not really a Pseudo, so don't mark 
it as such. Add some encoding information.

Dan Gohman 7e6b393e66 Factor out the code for purging a SCEV from all the various memoization maps. 
Some of these maps may merge in the future, but for now it's convenient to have
a utility function for them.

Dan Gohman 7ee1bbb76c Merge the implementations of isLoopInvariant and hasComputableLoopEvolution, and 
memoize the results. This improves compile time in code which highly complex
expressions which get queried many times.

Argyrios Kyrtzidis af84ec0a96 Introduce option -Wargument-larger-than[=N] which warns about function definitions if they take by-value 
or return by-value any POD that is larger than some threshold (default is 64 bytes).

Implements rdar://8548050.

Sean Callanan afe16a71f7 Added support for constant strings of the form @"this-is-a-string". 
They are replaced with calls to the CoreFoundation function 
CFStringCreateWithBytes() by a portion of the IRForTarget pass.

Dan Gohman 534749bf70 Make SCEV::getType() and SCEV::print non-virtual. Move SCEV::hasOperand 
to ScalarEvolution. Delete SCEV::~SCEV. SCEV is no longer virtual.

Dale Johannesen 0659c8f157 These tests are looking for library function names that 
appear to differ on Linux.  Try to make them pass on Linux.
Would be good for a Linux person to review this.

Douglas Gregor b4a7c0385d Do not produce "purely informative" code completion results for 
Objective-C message sends, which have only whitespace in their
TypedText chunk. Such results have no purpose.

Bob Wilson 881b45ccdf Change ARMGlobalMerge to keep BSS globals in separate pools. 
This completes the fixes for Radar 8673120.

llvm-svn: 119566
 2010-11-17 21:25:39 +00:00
Bob Wilson 4c8ab19c22 Fix ARMGlobalMerge pass to check if globals are entirely within range. 
It is generally not sufficient to check if the starting offset is in range
of the maximum offset that can be efficiently used for the target.

 2010-11-17 21:25:36 +00:00
Bob Wilson 59182fb4b5 Change the symbol for merged globals from "merged" to "_MergedGlobals". 
This makes it more clear that the symbol is an internal, compiler-generated
name and gives a little more description about its contents.

 2010-11-17 21:25:33 +00:00
Bob Wilson f796d4b469 Fix the ARMGlobalMerge pass to look at variable sizes instead of pointer sizes. 
It was mistakenly looking at the pointer type when checking for the size of
global variables.  This is a partial fix for Radar 8673120.

functions of ScalarEvolution, in preparation for memoization and
other optimizations.

Dan Gohman 1ee6d24072 Reference ScalarEvolution by name rather than directly in LICM, 
to avoid an unneeded dependence.

Duncan Sands 39d77131a1 Before replacing a phi node with a different value, it 
needs to be checked that this won't break LCSSA form.
Change the existing checking method to a more direct one:
rather than seeing if all predecessors belong to the loop,
check that the replacing value is either not in any loop or
is in a loop that contains the phi node.

Dan Gohman d3a32ae4c8 Verify SCEVAddRecExpr's invariant in ScalarEvolution::getAddRecExpr 
instead of in SCEVAddRecExpr's constructor, in preparation for an
upcoming change.

Rafael Espindola f92614c578 Don't warn about -w not being used in a link. Necessary to get sane 
results in the gdb testsuite.

Dan Gohman ed75631743 Fix ScalarEvolution's range memoization to avoid using a 
default ctor with ConstantRange.

llvm-svn: 119550
 2010-11-17 20:23:08 +00:00
Jim Ingham a80ef35902 Add a ThreadPlanAssemblyTracer that takes just a thread (since that's how we call it from ThreadPlanBase...)

Evan Cheng 7f8ab6ee8b Remove ARM isel hacks that fold large immediates into a pair of add, sub, and, 
and xor. The 32-bit move immediates can be hoisted out of loops by machine
LICM but the isel hacks were preventing them.

Instead, let peephole optimization pass recognize registers that are defined by
immediates and the ARM target hook will fold the immediates in.

Other changes include 1) do not fold and / xor into cmp to isel TST / TEQ
instructions if there are multiple uses. This happens when the 'and' is live
out, machine sink would have sinked the computation and that ends up pessimizing
code. The peephole pass would recognize situations where the 'and' can be
toggled to define CPSR and eliminate the comparison anyway.

2) Move peephole pass to after machine LICM, sink, and CSE to avoid blocking
important optimizations.

Duncan Sands c89ac07e7a Move some those Xor simplifications which don't require creating new 
instructions out of InstCombine and into InstructionSimplify.  While
there, introduce an m_AllOnes pattern to simplify matching with integers
and vectors with all bits equal to one.

Argyrios Kyrtzidis 14a96625b8 Don't warn for parentheses for the '&&' inside '||' for cases like: 
assert(a || b && "bad");

since this is safe. This way we avoid a big source of such warnings which in this case are practically useless.

Note that we don't handle *all* cases where precedence wouldn't matter because of constants since
this is a bit costly to check, and IMO clarifying precedence with parentheses is good for
readability in general.
