Yes. TARGET_HARD_FLOAT is defined as
#define TARGET_HARD_FLOAT ((target_flags & MASK_SOFT_FLOAT) == 0)
The -mhard-float option will clear the MASK_SOFT_FLOAT bit in
target_flags.
Yes, this option works when I use it in GDB like this,
(gdb) run -mhard-float
../../gcc-dfp-cvs-Aung-10/gcc/testsuite/gcc.dg/dfp/qiyao/varargs-1.expand -o
vararg-1.exe
and TARGET_HARD_FLOAT becomes *TRUE*. Thanks.
The default setting of the MASK_SOFT_FLOAT bit in target_flags depends
upon the default processor.
The condition is not always false. The value depends on exactly how
you have configured the compiler and exactly what options you pass.
