cpplib.h (CPP_N_WIDTH_MD, [...]): Add new constants.
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.
