Justin Bogner 880a1f20ab [FuzzMutate] Fix getWeight of InstDeleterIRStrategy ... The comment states the following, for calculating the Line variable: > Draw a line starting from when we only have 1k left and increasing > linearly to double the current weight. However, the value was not calculated as described. Instead, it would result in a negative value, which resulted in the function always returning 0 afterwards. ``` // Invariant: CurrentSize <= MaxSize - 200 // Invariant: CurrentWeight >= 0 int Line = (-2 * CurrentWeight) * (MaxSize - CurrentSize + 1000); // {Line <= 0} ``` This commit fixes the issue and linearly interpolates as described. Patch by Loris Reiff. Thanks! Differential Revision: https://reviews.llvm.org/D96207		2021-06-08 11:14:33 -07:00
