The fix for PR 78757 was slightly too cautious, and covered only the case of functions returning pointers to characters.

2016-12-20Use the middle-end boolean_type_nodeJanne Blomqvist2-4/+4
Use the boolean_type_node setup by the middle-end instead of redefining it. boolean_type_node is not used in GFortran for any ABI-visible stuff, only internally as the type of boolean expressions. There appears to be one exception to this, namely the caf_get* and caf_send* calls which have boolean_type_node arguments. However, on the library side they seem to use C _Bool, so I suspect this might be a case of a argument mismatch that hasn't affected anything so far. The practical effect of this is that the size of such variables will be the same as a C _Bool or C++ bool, that is, on most targets a single byte. Previously we redefined boolean_type_node to be a Fortran default logical kind sized variable, that is 4 or 8 bytes depending on compile options. This might enable slightly more compact code, in case the optimizer determines that the result of such a generated comparison expression needs to be stored in some temporary location rather than being used immediately. Regression tested on x86_64-pc-linux-gnu. 2016-12-20 Janne Blomqvist <jb@gcc.gnu.org> * trans-types.c (gfc_init_types): Don't redefine boolean type node. From-SVN: r243830
