[ScopInfo] Simplify inbounds assumptions under domain constraints Without this simplification for a loop nest: void foo(long n1_a, long n1_b, long n1_c, long n1_d, long p1_b, long p1_c, long p1_d, float A_1[][p1_b][p1_c][p1_d]) { for (long i = 0; i < n1_a; i++) for (long j = 0; j < n1_b; j++) for (long k = 0; k < n1_c; k++) for (long l = 0; l < n1_d; l++) A_1[i][j][k][l] += i + j + k + l; } the assumption: n1_a <= 0 or (n1_a > 0 and n1_b <= 0) or (n1_a > 0 and n1_b > 0 and n1_c <= 0) or (n1_a > 0 and n1_b > 0 and n1_c > 0 and n1_d <= 0) or (n1_a > 0 and n1_b > 0 and n1_c > 0 and n1_d > 0 and p1_b >= n1_b and p1_c >= n1_c and p1_d >= n1_d) is taken rather than the simpler assumption: p9_b >= n9_b and p9_c >= n9_c and p9_d >= n9_d. The former is less strict, as it allows arbitrary values of p1_* in case, the loop is not executed at all. However, in practice these precise constraints explode when combined across different accesses and loops. For now it seems to make more sense to take less precise, but more scalable constraints by default. In case we find a practical example where more precise constraints are needed, we can think about allowing such precise constraints in specific situations where they help. This change speeds up the new test case from taking very long (waited at least a minute, but it probably takes a lot more) to below a second. llvm-svn: 296456

Record assumptions first and add them later There are three reasons why we want to record assumptions first before we add them to the assumed/invalid context: 1) If the SCoP is not profitable or otherwise invalid without the assumed/invalid context we do not have to compute it. 2) Information about the context are gathered rather late in the SCoP construction (basically after we know all parameters), thus the user might see overly complicated assumptions to be taken while they would have been simplified later on. 3) Currently we cannot take assumptions at any point but have to wait, e.g., for the domain generation to finish. This makes wrapping assumptions much more complicated as they need to be and it will have a similar effect on "signed-unsigned" assumptions later. llvm-svn: 266068

Record wrapping assumptions early Utilizing the record option for assumptions we can simplify the wrapping assumption generation a lot. Additionally, we can now report locations together with wrapping assumptions, though they might not be accurate yet. llvm-svn: 266069

Optimistic assume required invariant loads to be invariant Before this patch we bailed if a required invariant load was potentially overwritten. However, now we will optimistically assume it is actually invariant and, to this end, restrict the valid parameter space as well as the execution context with regards to potential overwrites of the location. llvm-svn: 270416
