The results now produced by flang(-new) for Fujitsu Fortran test 0676_0160 are better than the desired results of the test.
The test uses the SUM intrinsic function to compute the sum of 100 complex numbers. These values are all identical. The new results from the SUM intrinsic function match the value of 100 times this value exactly. The expected value used by the test does not, and perhaps it reflects the result of a compiler using a less accurate summation method than flang is now using.
Should have been reported as below.

Hi Sergei,
It seems your patch below breaks build of several SPEC CPU2017 benchmarks on 32-bit ARM.
Could you please investigate? Please let me know if you need any assistance in reproducing build failures.
Thanks,

Hi there,
I can only locate the error message like "/tmp/cc4i9dn1.s:151930: Error: conditional branch out of range".
But failed to reproduce this when cross build, is there anywhere to get the build option for reproducing?
Thanks.

Function multi versioning is a nice feature for developers to target certain architecture features easily. [1][2]
