265752ae8f Ding dong, the DoesntAccessMemoryFns and 
OnlyReadsMemoryFns tables are dead!  We
get more, and more accurate, information
from gcc via the readnone and readonly
function attributes.

6690b9499b Fix handling of overflow in loop calculation by adding new UDiv SCEV. This SCEV 
is disabled in the sense that it will refuse to create one from a UDiv
instruction, until the code is better tested.

67d3119773 This resolves a regression of BasicAA which failed to find any memory information for overloaded intrinsics (PR1600). This resolves that issue, and improves the matching scheme to use a BitVector rather than a binary search.

071a2c6a5e Don't assume it's safe to transform a loop just because it's dominated by any 
comparison. Fixes bug 1598.

df17fa8ef9 For PR1319: 
Remove && from the end of the lines to prevent tests from throwing run
lines into the background. Also, clean up places where the same command
is run multiple times by using a temporary file.

cfa86314dd Changes to fix problems with "make check". Apparently you can redefine 
functions and Tcl's just tickled with that. The fix is to give the "new"
test system a different interface function name.

6ac77d03a8 Convert test cases to new llvm.exp version of llvm_runtest and fix tests 
that it found to be broken.

llvm-svn: 36008
 2007-04-14 19:10:21 +00:00
Reid Spencer
56b310ae49 Make the llvm-runtest function much more amenable by eliminating all the 
global variables that needed to be passed in. This makes it possible to
add new global variables with only a couple changes (Makefile and llvm-dg.exp)
instead of touching every single dg.exp file.

82293f34de For PR411: 
Update these tests to not use the same name even though the type of the
value differs. After PR411 hits, type planes will be gone and it will be
illegal for a name to be used twice, regardless of type.

6a31ec1259 For PR761: 
Remove "target endian/pointersize" or add "target datalayout" to make
the test parse properly or set the datalayout because defaults changes.

For PR645:
Make global names use the @ prefix.

For llvm-upgrade changes:
Fix test cases or completely remove use of llvm-upgrade for test cases
that cannot survive the new renaming or upgrade capabilities.
