Douglas Gregor 981a0c4613 When providing a code completion for an Objective-C message send, drop 
the parameter names from the completions, e.g., provide

  withString:(NSString *)

instead of

  withString:(NSString *)string

since the parameter name is, by convention, redundant with the
selector piece that precedes it and the completions can get
unnecessarily long.

Douglas Gregor 99129efdd3 Improve code completion for initializer lists in constructors. Instead 
of prioritizing just by initialization order, we bump the priority of
just the *next* initializer in the list, and leave everything else at
the normal priority. That way, if one intentionally skips the
initialization of a base or member (to get default initialization),
we'll still get ordered completion for the rest.

Chris Lattner f58382ed87 two changes: 1) make AliasSet hold the list of call sites with an 
assertingvh so we get a violent explosion if the pointer dangles.

2) Fix AliasSetTracker::deleteValue to remove call sites with
   by-pointer comparisons instead of by-alias queries.  Using
   findAliasSetForCallSite can cause alias sets to get merged
   when they shouldn't, and can also miss alias sets when the
   call is readonly.

#2 fixes PR6889, which only repros with a .c file :(

Chris Lattner 263f804699 LICM does get dead instructions input to it. Instead of sinking them 
out of loops, just delete them.

Chris Lattner 6ac0659a1c use moveBefore instead of remove+insert, it avoids some 
symtab manipulation, so its faster (in addition to being
more elegant)

Chris Lattner 11f8ad8211 optimize LICM::hoist to use moveBefore. Correct its updating 
of AST to remove the hoisted instruction from the AST, since it
is no longer in the loop.

 2010-08-29 18:03:33 +00:00
Chris Lattner 1a1ed69435 fix some bugs (found by inspection) where LICM would not update 
LICM correctly.  When sinking an instruction, it should not add
entries for the sunk instruction to the AST, it should remove
the entry for the sunk instruction.  The blocks being sunk to
are not in the loop, so their instructions shouldn't be in the
AST (yet)!

Chris Lattner cc9cbc66a3 rework the ownership of subloop alias information: instead of 
keeping them around until the pass is destroyed, keep them
around a) just when useful (not for outer loops) and b) destroy
them right after we use them.  This should reduce memory use
and fixes potential bugs where a loop is deleted and another
loop gets allocated to the same address.

Chris Lattner bc1a65ac6c apparently unswitch had the same "Feature". Stop its 
claims that it preserves domfrontier if it doesn't really.

 2010-08-29 17:23:19 +00:00
Chris Lattner d6f46b8af8 now that loop passes don't use DomFrontier, there is no reason 
for the unroller to pretend it supports updating it.  It still
has a horrible hack for DomTree.

This has the side effect of reversing the order of most of
IVUser's results.

Dan Gohman 002ff89cbd Optionally rerun dedicated-register filtering after applying 
other filtering techniques, as those may allow it to filter
out more obviously unprofitable candidates.

Chris Lattner 0c4deab098 Stop explicitly scheduling domfrontier before the loop passes, 
since none of them use it.  With this, we now only run 
domfrontier (an N^2 analysis) 3 times at clang -O3: once for 
"early" per-function cleanup, once at the start of the
per-function pipeline to support SRoA, and once late because
the EHPrepare class uses it.

EHPrepare needs to stop using it, this is silly and wasteful.

Chris Lattner f94f6bb0ba licm preserves the cfg, it doesn't have to explicitly say it 
preserves domfrontier.  It does preserve AA though.

Chris Lattner abe61ef3b4 now that it doesn't use the PromoteMemToReg function, LICM doesn't 
require DomFrontier.  Dropping this doesn't actually save any runs
of the pass though.

Chris Lattner 1dc98b47b5 completely rewrite the memory promotion algorithm in LICM.

Bob Wilson d0c054886c Remove NEON vaddl, vaddw, vsubl, and vsubw intrinsics. Instead, use llvm

Bob Wilson 0e7a398936 Translate NEON vaddl, vaddw, vsubl, and vsubw builtins to llvm add/sub 
with zext/sext operations, instead of to llvm intrinsics.  (We can also
get rid of the clang builtins and handle these entirely in the arm_neon.h
header if there is a way to express vector sext/zext in C.)
