Tobias Grosser	0905a23806	CodeGen: Recreate old ivs with the original type To avoid overflows we still use a larger type (i64) while calculating the value of the old ivs. However, we truncate the result to the type of the old iv when providing it to the new code. A corresponding test case is added to the polly test suite. Also, a failing test case is fixed. This fixes PR12311.

Tobias Grosser	d6adda3071	CodeGen: Full support for isl_pw expressions in modified access functions. This also adds support for modifiable write accesses (until now only read accesses where supported). We currently do not derive an exact type for the expression, but assume that i64 is good enough. This will be improved in future patches. Contributed by: Yabin Hu <yabin.hwu@gmail.com> llvm-svn: 153319	2012-03-23 08:21:22 +00:00

CodeGen: Recreate old ivs with the original type

To avoid overflows we still use a larger type (i64) while calculating the value
of the old ivs.  However, we truncate the result to the type of the old iv when
providing it to the new code.

A corresponding test case is added to the polly test suite. Also, a failing test
case is fixed.

This fixes PR12311.
