[RFA/testsuite/ada] Test "set print array-indexes" with Ada arrays

[Joel Brobecker <brobecker@adacore.com>]

[-- Attachment #1: Type: text/plain, Size: 807 bytes --]

Hello,

Given the larger range of possible arrays that can be defined in Ada
compared to C, I wanted to add a new testcase for this recently added
feature using Ada code. It turned out to be a good idea, because I found
one bug. I can't look into it yet, but I created a PR. I'm still waiting
for the PR number to arrive, but here is the testcase. I will replace
the "????" by the actual PR number as soon as I receive my confirmation
email. In the meantime, I can use this testcase as the testcase for an
upcoming patch.

2005-10-05  Joel Brobecker  <brobecker@adacore.com>

        * gdb.ada/arrayidx/p.adb: New file.
        * gdb.ada/arrayidx.exp: New testcase

Tested on x86-linux. There are 12 PASSes, 2 FAILs, and 4 KFAILs.
The patch I'm about to submit will fix the 2 FAILs.

OK to commit?

# because the underlying value of the first enumeration is zero, the
# debugger ends up printing this index even when "array-indexes" are
# off, just because the index of the first element is not an enumerated
# type, and its value is not one.
