commit r17-2165-g6cc7df8e83417dd495ff124cb6e6560b300ca17e Author: Eric Botcazou <[email protected]> Date: Sat Jul 4 10:03:34 2026 +0200 Remove left-overs of WIDEST_HARDWARE_FP_SIZE This removes the single remaining use of WIDEST_HARDWARE_FP_SIZE in GCC, which has been anectodal for a long time, and all the associated bits. gcc/ * config/aarch64/aarch64.h (WIDEST_HARDWARE_FP_SIZE): Delete. * config/alpha/alpha.h (WIDEST_HARDWARE_FP_SIZE): Likewise. * config/i386/i386.h (WIDEST_HARDWARE_FP_SIZE): Likewise. * config/ia64/vms.h (WIDEST_HARDWARE_FP_SIZE): Likewise. * config/pa/pa.h (WIDEST_HARDWARE_FP_SIZE): Likewise. * config/rs6000/rs6000.h (WIDEST_HARDWARE_FP_SIZE): Likewise. * config/s390/s390.h (WIDEST_HARDWARE_FP_SIZE): Likewise. * config/sparc/sparc.h (WIDEST_HARDWARE_FP_SIZE): Likewise. * config/visium/visium.h (WIDEST_HARDWARE_FP_SIZE): Likewise. * doc/tm.texi.in (WIDEST_HARDWARE_FP_SIZE): Likewise. * doc/tm.texi: Regenerate. * system.h (WIDEST_HARDWARE_FP_SIZE): Poison. gcc/ada/ * gcc-interface/decl.cc (gnat_to_gnu_entity): Use the precision of longest_float_type_node to compute the maximum size of FP types.
