Remove TYPE_NOSIGN "char" hack
|
||
|
|
|
||
|
|
init_type (and arch_integer_type) currently use a special hack to set the
|
||
|
|
TYPE_NOSIGN flag if the type name is exactly "char". This commit moves the
|
||
|
|
hack up to the callers of those routines.
|
||
|
|
|
||
|
|
The special case currently can hit only for types created from dwarf2read,
|
||
|
|
but read_base_type actually implements the "char" check itself, so it is
|
||
|
|
redundant to do it in init_type as well. (Note that stabsread.c and the
|
||
|
|
other type readers always pass NULL as name to init_type, so the special
|
||
|
|
case can never hit for those.)
|
||
|
|
|
||
|
|
A few other cases create pre-definded types with a hard-coded name of "char";
|
||
|
|
the commit simply moves setting the TYPE_NOSIGN flag to those places.
|
||
|
|
|
||
|
|
No functional change intended.
