URL: https://github.com/llvm/llvm-project/commit/0e9881745834863a6f5a3a05588886bb3eb75cdf DIFF: https://github.com/llvm/llvm-project/commit/0e9881745834863a6f5a3a05588886bb3eb75cdf.diff LOG: libclc: frexp: fix implementation regarding denormals (#134823) Devices not supporting denormals can compare them true against zero. It leads to result not matching the CTS expectation when either supporting or not denormals. For example for 0x1.008p-140 we get {0x1.008p-140, 0} while the CTS expects {0x1.008p-1, -139} when supporting denormals, or {0, 0} when not supporting denormals (flushed to zero).
