getBitRangeFromMask()

static SmallString< 32 > getBitRangeFromMask ( uint32_t  Mask, unsigned  BaseBytes  )

static

Print a string describing the reserved bit range specified by Mask with offset BaseBytes for use in error comments.

Mask is a single continuous range of 1s surrounded by zeros. The format here is meant to align with the tables that describe these bits in llvm.org/docs/AMDGPUUsage.html.
