* defs.h: Move definitions of TARGET_*_BIT after include of tm.h.
The old way (using #undef in tm.h) was ugly and asking for trouble, because it makes it possible for some file to use the wrong definition. Move definition of HOST_CHAR_BIT after definition of TARGET_CHAR_BIT. * config/alpha/tm-alpha.h, config/h8300/tm-h8300.h, config/h8500/tm-h8500.h, config/z8k/tm-z8k.h: Don't undef TARGET_*_BIT before defining them.

* defs.h: Move definitions of TARGET_*_BIT after include of tm.h.
|
||||
The old way (using #undef in tm.h) was ugly and asking for
|
||||
trouble, because it makes it possible for some file to use the
|
||||
wrong definition. Move definition of HOST_CHAR_BIT after definition
|
||||
of TARGET_CHAR_BIT.
|
||||
* config/alpha/tm-alpha.h, config/h8300/tm-h8300.h,
|
||||
config/h8500/tm-h8500.h, config/z8k/tm-z8k.h: Don't undef TARGET_*_BIT
|
||||
before defining them.
|
||||
|
||||
* mdebugread.c: Change the builtin_type_* in this file to
|
||||
mdebug_type_* and make them static. Use TYPE_CODE_ERROR for
|
||||
complex and float decimal.
