gdb: fix debug dump of OP_BOOL expressions
Consider this GDB session:
(gdb) set language fortran
(gdb) set debug expression 1
(gdb) p .TRUE.
Dump of expression @ 0x4055d90, before conversion to prefix form:
Language fortran, 3 elements, 16 bytes each.
Index Opcode Hex Value String Value
0 OP_BOOL 79 O...............
1 BINOP_ADD 1 ................
2 OP_BOOL 79 O...............
Dump of expression @ 0x4055d90, after conversion to prefix form:
Expression: `TRUE'
Language fortran, 3 elements, 16 bytes each.
0 OP_BOOL Unknown format
1 BINOP_ADD
2 OP_BOOL Unknown format
3 OP_NULL Unknown format
$1 = .TRUE.
The final dump of the OP_BOOL is completely wrong. After this patch
we now get:
(gdb) set language fortran
(gdb) set debug expression 1
(gdb) p .TRUE.
Dump of expression @ 0x2d07470, before conversion to prefix form:
Language fortran, 3 elements, 16 bytes each.
Index Opcode Hex Value String Value
0 OP_BOOL 79 O...............
1 BINOP_ADD 1 ................
2 OP_BOOL 79 O...............
Dump of expression @ 0x2d07470, after conversion to prefix form:
Expression: `TRUE'
Language fortran, 3 elements, 16 bytes each.
0 OP_BOOL TRUE
$1 = .TRUE.
Much better. I added a test for this into the Fortran testsuite.
gdb/ChangeLog:
* expprint.c (dump_subexp_body_standard): Handle OP_BOOL.
gdb/testsuite/ChangeLog:
* gdb.fortran/debug-expr.exp: Add new tests.
