Hi Jakub,
Thank you for taking this on (this patch and the Fortran ones), it is really
appreciated and will improve gfortran's IEEE conformance.
- "Implement __builtin_issignaling”: is approved for the tiny Fortran part
- "libgfortran: Use __builtin_issignaling in libgfortran”: was approved by
Thomas
- I will have to look at the next two patches (ieee_value and ieee_class) in
the next few days. I think we can make adjustments to the runtime library as
well.
Related: there are several tests in our testsuite that have {
dg-require-effective-target issignaling }
This is checked by check_effective_target_issignaling in
gcc/testsuite/lib/target-supports.exp, and probes the support for the
issignaling macro in <math.h>. I think it would make sense to adjust those
tests to run on a wider range of targets, using the new built-in.
