Pass void_context_p to parse_expression
An earlier patch pointed out that nothing in GDB sets void_context_p when parsing an expression. This patch fixes this omission. "print" and "call" differ in that the former will print a value that has void type, while the latter will not. AdaCore has had a patch for a long time that uses this distinction to help with overload resolution. In particular, in a "call" context, a procedure will be chosen, while in a "print" context, a zero-argument function will be chosen instead. Regression tested on x86-64 Fedora 32. gdb/ChangeLog 2021-01-08 Tom Tromey <tromey@adacore.com> * parse.c (parse_expression): Add void_context_p parameter. Use parse_exp_in_context. * printcmd.c (print_command_1): Change voidprint to bool. Pass to parse_expression. (print_command, call_command): Update. * expression.h (parse_expression): Add void_context_p parameter. gdb/testsuite/ChangeLog 2021-01-08 Tom Tromey <tromey@adacore.com> * gdb.ada/voidctx/pck.adb: New file. * gdb.ada/voidctx/pck.ads: New file. * gdb.ada/voidctx/voidctx.adb: New file. * gdb.ada/voidctx.exp: New file.
