No. The compiler on FreeBSD/amd64 is capable of generating both 64 and
32 -bit binaries, so decision should be done at runtime. I.e. I want
something like this:
#define SUBTARGET_OVERRIDE_OPTIONS \
if ( !TARGET_64 ) {
real_format_for_mode[XFmode - QFmode] \
= &ieee_extended_intel_96_round_53_format; \
real_format_for_mode[TFmode - QFmode] \
= &ieee_extended_intel_96_round_53_format; \
}
see gcc/config/i386/i386.h for TARGET_64 definition.
