Daniel Dunbar fdda3501a0 Darwin x86_32: Ignore padding bit-fields when looking for "single 
element" structures.

llvm-svn: 71266
 2009-05-08 21:04:47 +00:00
Dan Gohman 2e55cc5a4a Fold trunc casts into add-recurrence expressions, allowing the 
add-recurrence to be exposed. Add a new SCEV folding rule to
help simplify expressions in the presence of these extra truncs.

Bill Wendling fa03b0084a Compute the offsets of the compile units. We need this so that when we emit a 
concrete instance of an inlined function, we can get the actual address of the
abstract instance inside of the compile unit.

This isn't currently used, but will be by a future check-in.

Dan Gohman c05bb947c4 Fix another bug in r71252. This code supports GetElementPtr 
constant exprs as well as instructions.

Daniel Dunbar 4861346c44 Darwin x86_32: Improve bit-field handling for returning records. 
- This turns out to be a no-op now that most of the handling for
   everything else is in place.

 2009-05-08 20:55:49 +00:00
Bill Wendling 9ee6a31bb8 Fix typo. 
llvm-svn: 71260
 2009-05-08 20:49:29 +00:00
Dan Gohman 5122d6152e Add memoization for getSCEVAtScope results for instructions 
which are not analyzed with SCEV techniques, which can require
brute-forcing through a large number of instructions. This
fixes a massive compile-time issue on 400.perlbench (in
particular, the loop in MD5Transform).

llvm-svn: 71259
 2009-05-08 20:47:27 +00:00
Dan Gohman b81f47d191 Make the SCEV* form of getSCEVAtScope public, to allow ScalarEvolution 
clients to use it.

separate function.

Daniel Dunbar 85f4028f2e Darwin x86_32: Ignore arrays of empty structures inside records. 
- This eliminates 5/1000 failures on return-types-32, on the current
   ABITest config.

Fariborz Jahanian fe9e3940eb Refactoring of my last patch. 
llvm-svn: 71248
 2009-05-08 20:20:55 +00:00
Dan Gohman c3a3cb47d2 Implement several new SCEV folding rules for UDiv SCEVs. 
This fixes an old FIXME, and is needed by some upcoming changes.

llvm-svn: 71247
 2009-05-08 20:18:49 +00:00
Daniel Dunbar 51c4bc320e ABITest: Move default set of test args into common makefile. 
Also, tweak default list of bit-fields to try.

llvm-svn: 71246
 2009-05-08 20:10:52 +00:00
Dan Gohman bd953333f8 Add a getExitBlock utility function to LoopInfo which returns the 
exit block of a loop, if there is exactly one, similar to
getExitingBlock.

patch by Mikael Lepistö!

llvm-svn: 71226
 2009-05-08 17:32:47 +00:00
Chris Lattner c48091f141 fix RewriteStoreUserOfWholeAlloca to use the correct type size 
method, fixing a crash on PR4146.  While the store will 
ultimately overwrite the "padded size" number of bits in memory,
the stored value may be a subset of this size.  This function
only wants to handle the case where all bits are stored.

Chris Lattner a02cb80f99 "This patch fixes message sends to super in categories for the GNU runtime. This used to work, but I broke it when I modified the code to emit the same thing as GCC for message sends to super in classes." 
Patch by David Chisnall!

llvm-svn: 71220
 2009-05-08 15:39:58 +00:00
Chris Lattner 5b9241b2a6 Fix the atomics sema code to convert operands to the argument types 
of the underlying _N builtin, not the the type of the pointee of the
actual type.  This ensures that atomics involving pointers end up
using the correct integer type when they are resolved, avoiding
aborts in codegen.

Chris Lattner dc04654697 reimplement __sync_* builtins to be variadic and to follow the same 
semantic rules that gcc and icc use.  This implements the variadic
and concrete versions as builtins and has sema do the 
disambiguation.  There are probably a bunch of details to finish up
but this seems like a large monotonic step forward :)
