gdb/fortran: Fix printing of logical true values for Flang
GDB is not able to print logical true values for Flang compiler.
Actual result:
(gdb) p l
$1 = 4294967295
Expected result:
(gdb) p l
$1 = .TRUE.
This is due to GDB expecting representation of true value being 1.
The Fortran standard doesnt specify how LOGICAL types are represented.
Different compilers use different non-zero values to represent logical
true. The gfortran compiler uses 1 to represent logical true and the
flang compiler uses -1. GDB should accept all the non-zero values as
true.
This is achieved by handling TYPE_CODE_BOOL in f_val_print and
printing any non-zero value as true.
gdb/ChangeLog:
* f-valprint.c (f_val_print): Handle TYPE_CODE_BOOL, any non-zero
value should be printed as true.
gdb/testsuite/ChangeLog:
* gdb.fortran/logical.exp: Add tests that any non-zero value is
printed as true.
