The information for QUIET_NAN_NEGATED is in the > qnan_msb_set field of struct real_format, I suppose. I had a look at this option, but see two problems: * qnan_msb_set is stored per-format, so we'd have to introduce something like __LIBGCC_SF_QUIET_NAN_NEGATED__, __LIBGCC_DF_QUIET_NAN_NEGATED__, ..., which seems ugly. * Even worse, there are a couple of formats/targets that do use fp-bit.c, don't yet define QUIET_NAN_NEGATED, but have qnan_msb_set = false: qnan_msb_set uses fp-bit mips_single_format false x spu_single_format false x mips_double_format false x mips_extended_format false x mips_quad_format false x vax_f_format false 00 vax_d_format false 00 vax_g_format false 00 arm_half_format false ? So such a change would mean a change of behavior for spu and arm targets. Given those issues, I'd rather leave -DQUIET_NAN_NEGATED in libgcc/config/mips/t-{fd, t}pbit, at least for now. > How does your code replace the "#if __LDBL_MANT_DIG__ == 113" condition > that stops tp-bit.c being built for o32 multilibs that don't have TFmode? > > (The best way would I think be configure tests in libgcc that cause > tp-bit.c only to be built at all for the relevant multilibs for this > target.) As discussed, this is the route I've chosen: I'm determining double_type_size and long_double_type_size in libgcc/configure.ac, substitute the result in libgcc/Makefile, and evaluate it in libgcc/config/{mips/tpbit, rx/t-rx}. Bootstrapped without regressions on x86_64-unknown-linux-gnu. Bootstraps on i386-pc-solaris2.10, sparc-sun-solaris2.11, alpha-dec-osf5.1b, mips-sgi-irix6.5, and i386-apple-darwin9.8.0 still running. Ok for mainline if they pass? Thanks.
