test index.

Makefile.

Daniel Dunbar 811e62c8c1 ABITest: Fix a bug in generating test values for structures w/ no 
non-padding fields.

llvm-svn: 71273
 2009-05-08 22:48:39 +00:00
Daniel Dunbar b997f3bcc3 x86_64 ABI: Ignore padding bit-fields during classification. 
- {return-types,single-args}-{32,64} pass the first 1k ABI tests with
   bit-fields enabled.

llvm-svn: 71272
 2009-05-08 22:26:44 +00:00
Daniel Dunbar 4752783057 Darwin x86_32: When coercing a "single element" structure, make sure 
to use a wide enough type. This might be wider than the "single
element"'s type in the presence of padding bit-fields.
 - Darwin x86_32 now passes the first 1k ABI tests with bit-field
   generation enabled.

llvm-svn: 71270
 2009-05-08 21:30:11 +00:00
Bill Wendling 8881780832 Mirror how Fast ISel determines if a region.end intrinsic is the end of an 
inlined function or the end of a function. Before, this was never executing the
"inlined" version of the Record method.

This will become important once the inlined Dwarf writer patch lands.

llvm-svn: 71268
 2009-05-08 21:14:49 +00:00
Fariborz Jahanian 3e68a1facc Fixes a bug in my last patch. Order of types reversed. 
llvm-svn: 71267
 2009-05-08 21:10:00 +00:00
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.

llvm-svn: 71264
 2009-05-08 21:03:19 +00:00
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.

llvm-svn: 71263
 2009-05-08 21:03:15 +00:00
Dan Gohman c05bb947c4 Fix another bug in r71252. This code supports GetElementPtr 
constant exprs as well as instructions.

llvm-svn: 71262
 2009-05-08 20:58:38 +00:00
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.

llvm-svn: 71261
 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.

llvm-svn: 71258

separate function.

 2009-05-08 20:26:55 +00:00
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.

llvm-svn: 71250
 2009-05-08 20:21:04 +00:00

 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.

llvm-svn: 71245
 2009-05-08 20:07:23 +00:00
Ted Kremenek 3a0516b25a retain checker: Track the number of times a tracked object is sent 
'autorelease'. This isn't used yet to flag errors.

Fariborz Jahanian b2ab73d93c More type checking for properties, accessors and 
use of dot-syntax expression. This is to match gcc's.

Chris Lattner f1d9b91434 Fix PR4152: asm constraint validation happens before dag combine, so we 
need to work a bit to combine things like (x+c1+c2) into x+c3.
