Summary: When the sample profiles include discriminator information, use the discriminator values to distinguish instruction weights in different basic blocks. This modifies the BodySamples mapping to map <line, discriminator> pairs to weights. Instructions on the same line but different blocks, will use different discriminator values. This, in turn, means that the blocks may have different weights. Other changes in this patch: - Add tests for positive values of line offset, discriminator and samples. - Change data types from uint32_t to unsigned and int and do additional validation.
