Fix function call regression in new evaluator

The internal AdaCore test suite revealed a bug in the new evaluator.
A hunk of evaluate_funcall was not correctly transcribed.  This was
not caught in my original testing because the feature in question was
apparently not tested in gdb.

This patch fixes the oversight.  The idea here is that ordinary
function calls should use the function's formal parameter types as the
expected types of subexpressions.

Regression tested on x86-64 Fedora 32.

bfd: don't silently wrap or truncate PE image section RVAs

In PE images section addresses get expressed as addresses relative to
the image base. Therefore the VA of a section must be no less than the
image base, and after subtraction of the image base the resulting value
should fit in 32 bits. (The issue is particularly obvious to notice when
sections, perhaps because of ELF assumptions, get placed at VA 0 by
default. Debugging info sections as well as .comment, when input files
are ELF, are a good example. All such sections need proper mentioning in
the linker script to avoid this warning.)

There are a number of test cases which previously produced bogus images,
yet still declared the test a success. Like done for other tests
already, force a zero image base for these. This then also allows (and
requires) dropping again xfail-s which 39a7b38fac0e ("Fix linker tests
to work with 16-bit targets") had added to ld-scripts/default-script*.d

testsuite/ld-scripts/map-address.* made by an earlier patch.

For ld-scripts/print-memory-usage.* I suppose xcoff could be dropped
from the exclusion list by suppressing garbage collection, just like
already done in e.g. (as seen in the diff here) ld-scripts/data.*, but I

in-tree caller of this was from dump_prefix_expression, which is only
called when expression debugging is enabled.  Implementing this would

Because byacc has poor support for C++, a stack of operations is added

for combination into new operations.  This approach avoids the memory
leaks that would result if raw pointers were used in the parsers, at
the cost of parser productions not being type-safe (they can't

3 years agoImplement Ada assignment
Tom Tromey [Mon, 8 Mar 2021 14:27:57 +0000 (07:27 -0700)]
Implement Ada assignment

Assignment is the most complicated Ada expression, because
implementing aggregate assignment involves several specialized
opcodes.

This patch does this implementation by introducing new abstract
classes that are used to represent the various parts of aggregate
assignment.  This makes the code somewhat cleaner, and, by avoiding
the over-use of 'operation' subclasses, avoids the need for dissection
using dynamic_cast (though a few are still needed here).

I believe this patch fixes a latent bug in the handling of
aggregate_assign_from_choices.  That code does:

      if (op == OP_DISCRETE_RANGE)
{
  choice_pos += 1;
  lower = value_as_long (ada_evaluate_subexp (NULL, exp, pos,
      EVAL_NORMAL));
  upper = value_as_long (ada_evaluate_subexp (NULL, exp, pos,
      EVAL_NORMAL));
}

However, I think 'choice_pos' should be used in the calls, rather than
'pos'.

3 years agoImplement Ada resolution
Tom Tromey [Mon, 8 Mar 2021 14:27:57 +0000 (07:27 -0700)]
Implement Ada resolution

Ada has a parser post-pass that implements "resolution".  This process
replaces some opcodes with function calls.  For example, a "+"
operation might be replaced with a call to the appropriate overloaded
function.

This differs from the approach taken for the same problem in C++.
However, in this series I chose not to try to make changes outside of
rewrite the expression data structure.  So, resolution remains.

The new approach to resolution is to introduce an interface class,
that some concrete operations implement.  Then, the Ada code will use
this to resolve the expression tree.  Because new-style expressions
are built as ordinary objects, and don't require rewriting the data
structure in place, in the new code this processing will be done in
the parser.  By the end of the series, some special cases in this area
that exist only for Ada will be removed.
