I'm not quite sure I understand the expected status of this patch: are
all the "expected" failures tagged as XFAIL?
I think that's the idea.
If yes, then there's a problem because I see lots of unresolved on
aarch64/arm
XFAIL: gfortran.dg/c-interop/cf-descriptor-5.f90 -O0 pr92482 (test
for bogus messages, line 10)
PASS: gfortran.dg/c-interop/cf-descriptor-5.f90 -O0 (test for
excess errors)
UNRESOLVED: gfortran.dg/c-interop/cf-descriptor-5.f90 -O0
compilation failed to produce executable
I think that's the usual result for 'dg-do run' tests if the compilation
failed (be it due to errors or due to effective-target-*).

If I read https://gcc.gnu.org/onlinedocs/gcc/Floating-Types.html
correctly, we should use _Float128 for the following errors
"The _Float128 type is supported on all systems where __float128 is
supported or where long double has the IEEE binary128 format."
Applies to:
For

On a normal x86-64 system, I get XPASS for:
gfortran.dg/PR100914.f90
gfortran.dg/c-interop/typecodes-array-float128.f90
The ! { dg-do run { xfail { { x86_64*-*-* i?86*-*-* } && longdouble128 } } }
does not help as it just checks whether 'sizeof(long double)==16',
which seemingly passes also on x86-64 with 80bit long double.
