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 --- gcc/target.h | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'gcc/target.h') diff --git a/gcc/target.h b/gcc/target.h index 7e144dec19a..effd93345dd 100644 --- a/gcc/target.h +++ b/gcc/target.h @@ -798,6 +798,13 @@ struct gcc_target enum machine_mode, struct secondary_reload_info *); + /* Functions specific to the C family of frontends. */ + struct c { + /* Return machine mode for non-standard suffix + or VOIDmode if non-standard suffixes are unsupported. */ + enum machine_mode (*mode_for_suffix) (char); + } c; + /* Functions specific to the C++ frontend. */ struct cxx { /* Return the integer type used for guard variables. */ -- cgit v1.2.1
