libcpp/ChangeLog:
* include/cpplib.h (CPP_N_WIDTH_MD, CPP_N_MD_W, CPP_N_MD_Q): Add new constants. * expr.c (interpret_float_suffix): Process 'w', 'W', 'q' and 'Q' suffixes. Return CPP_N_MD_W for 'w' or 'W' suffixes and CPP_N_MD_Q for 'q' or 'Q' suffixes. gcc/ChangeLog: * targhooks.h (default_mode_for_suffix): New function declaration. * targhooks.c (default_mode_for_suffix): New default target hook. * target.h (struct c): New structure in the targetm struct. (mode_for_suffix): New target hook as part of struct c. target-def.h (TARGET_C_MODE_FOR_SUFFIX): Define as default_mode_for_suffix. (TARGET_C): New define. * c-lex.c: Include "target.h". (interpret_float): Use targetm.c.mode_for_suffix to determine the mode for a given non-standard suffix. Makefile.in (c-lex.o): Depend on $(TARGET_H). * config/i386/i386.c (ix86_c_mode_for_suffix): New static function. (TARGET_C_MODE_FOR_SUFFIX): Define to ix86_c_mode_for_suffix. * doc/extend.texi (Floating Types): New node. Document __float80 and __float128 types. Document 'w', 'W', 'q' and 'Q' suffixes. testsuite/ChangeLog: * gcc.dg/const-float80.c : New test. * gcc.dg/const-float128.c : New test. * gcc.dg/const-float80-ped.c : New test. * gcc.dg/const-float128-ped.c : New test. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@126244 138bc75d-0d04-0410-961f-82ee72b054a4
