Tobias Grosser	3281f601bb	[ScopInfo] Always derive upper and lower bounds for parameters ... Commit r230230 introduced the use of range metadata to derive bounds for parameters, instead of just looking at the type of the parameter. As part of this commit support for wrapping ranges was added, where the lower bound of a parameter is larger than the upper bound: { 255 < p || p < 0 } However, at the same time, for wrapping ranges support for adding bounds given by the size of the containing type has acidentally been dropped. As a result, the range of the parameters was not guaranteed to be bounded any more. This change makes sure we always add the bounds given by the size of the type and then additionally add bounds based on signed wrapping, if available. For a parameter p with a type size of 32 bit, the valid range is then: { -2147483648 <= p <= 2147483647 and (255 < p or p < 0) } llvm-svn: 295349	2017-02-16 18:39:14 +00:00

Tobias Grosser	f4ee371e60	tests: Drop -polly-detect-unprofitable and -polly-no-early-exit ... These flags are now always passed to all tests and need to be disabled if not needed. Disabling these flags, rather than passing them to almost all tests, significantly simplfies our RUN: lines. llvm-svn: 249422	2015-10-06 15:36:44 +00:00
