Dan Gohman d131e18dd0 Add a testcase for the GlobalOpt inbounds fix. 
llvm-svn: 81168
 2009-09-07 23:04:59 +00:00
Chris Lattner ec72b9bbcf describe undef semantics in some more detail.

 2009-09-07 22:52:39 +00:00
Dan Gohman 02e363ed52 Add inbounds to these getelementptrs, now that GlobalOpt requires this, 
to preserve the meaning of these tests.

Dan Gohman 161429fe7e Don't commit stores with addresses that have indices that are not 
compile-time constant integers or that are out of bounds for their
corresponding static array types. These can cause aliasing that
GlobalOpt assumes won't happen.

llvm-svn: 81165
 2009-09-07 22:44:55 +00:00
Dan Gohman 82e747580f Don't commit addresses of aggregate values. This avoids problems with 
an aggregate store overlapping a different aggregate store, despite
the stores having distinct addresses.

llvm-svn: 81164
 2009-09-07 22:42:05 +00:00
Dan Gohman beee35a277 Fix GlobalOpt to avoid committing a store if the address getelementptr 
is missing the inbounds flag. This is slightly conservative, but it
avoids problems with two constants pointing to the same address but
getting distinct entries in the Memory DenseMap.

llvm-svn: 81163
 2009-09-07 22:40:13 +00:00
Dan Gohman 19244eaa4a Preserve the InBounds flag when evaluating a getelementptr instruction 
into a getelementptr ConstantExpr.

Daniel Dunbar d6b6c59729 Use -output-prefix in bugpoint tests so that outputs go in temp directory (and 
we don't race on them).

llvm-svn: 81155
 2009-09-07 19:26:18 +00:00
Daniel Dunbar a53337f731 Add -output-prefix option to bugpoint (to change the default output name). 
llvm-svn: 81154
 2009-09-07 19:26:11 +00:00
Daniel Dunbar 7fcfc4fc31 Don't depend on Tcl behavior of redirecting stderr for all commands in a 
pipeline.

llvm-svn: 81153
 2009-09-07 19:26:02 +00:00
Daniel Dunbar 0367b0f136 Avoid Tcl substitution, introduced %llvmgcc_only for this one little test 
(%llvmgcc includes a '-w' argument, and this test looks for warnings).

Anders Carlsson 85ec4ffaf5 Check that the destination type of a static_cast expression is a complete type.

Duncan Sands cd32ecf44f Using a signal handler that does nothing should be

Daniel Dunbar 8feee907e4 Update unittests for MDNode uniquing disable. 
llvm-svn: 81142
 2009-09-07 04:19:02 +00:00
Daniel Dunbar 10fcf3354b Disable MDNode uniquing. 
- Hopefully this unbreaks some llvm-gcc bootstraps.

Daniel Dunbar d027a92431 Use a SetVector for tracking some Obj-C metadata, to ensure deterministic 
output.
 - Also, cleanup code to output inline asm references.

Anton Korobeynikov d2c19c74d6 Do not create calls via PLT in compilation callback - this is higly platform 
dependent. Hopefully, this will fix PR3801.

llvm-svn: 81132
 2009-09-06 20:21:48 +00:00
Duncan Sands 4827538f82 Do not try to override non-virtual methods, especially 
when the new method gives the same result as the original
(as far as I can see).  This will hopefully pacify icc.

Anders Carlsson faf1ced5ee Reapply 81096, now with a fix. Spot the bug: 
for (unsigned i = numargs; i < NumArgs; ++i)
        Args[0] = 0;

 2009-09-06 12:41:19 +00:00
Benjamin Kramer 2b37efaf53 More MSVC warning fixes: 
1. DUPMAX is defined in regcomp.c, no need to redefine it in regutils.
2. MSVC doesn't like snprintf, use _snprintf instead.

Daniel Dunbar 86c6a6ef0f Fix a possible crash call setIsInBounds. 
- I think there are more instances of this, but I think they are fixed in Dan's
   incoming patch. This one was preventing me from doing a bugpoint reduction
   though.
