Some of this seems to be maybe the upstream rust change
we diagnosed last time around? Where the old-style "DISR"
stuff got mutated (probably also by me)?
I have a patch that improves some of it.
I'm still looking into some other failures.

Well, the trigger for the FAIL is the gdb commit mentioned above.
If the cause of the FAIL is this (
https://github.com/rust-lang/rust/issues/65204 ) rustc bug (I'm guessing this
is what you're referring to), we can add xfails , as we did in commit
a50faaf620 "[gdb/testsuite] Add XFAILs in gdb.rust/simple.exp for incorrect
DWARF".

--- Comment #8 from Tom Tromey <tromey at sourceware dot org> ---
Consider the NonZeroOptimized enum from your executable
<2><42c2>: Abbrev Number: 11 (DW_TAG_union_type)
<42c3> DW_AT_name : (indirect string, offset: 0x2f62):
NonZeroOptimized
<42c7> DW_AT_byte_size : 24
<42c8> DW_AT_alignment : 8
<3><42c9>: Abbrev Number: 9 (DW_TAG_member)
<42ca> DW_AT_name : (indirect string, offset: 0x26ea):
RUST$ENCODED$ENUM$0$Empty
<42ce> DW_AT_type : <0x42d5>
<42d2> DW_AT_alignment : 8
<42d3> DW_AT_data_member_location: 0
This means that slot 0 of the value is the discriminant, where 0
means it is the empty enum "Empty", and nonzero means it is the value.
However when we look at the type of the member:
<2><42d5>: Abbrev Number: 8 (DW_TAG_structure_type)
<42d6> DW_AT_name : (indirect string, offset: 0x2704): Value
<42da> DW_AT_byte_size : 24
<42db> DW_AT_alignment : 8
<3><42dc>: Abbrev Number: 9 (DW_TAG_member)
<42dd> DW_AT_name : (indirect string, offset: 0x67c): __0
<42e1> DW_AT_type : <0x44f2>
<42e5> DW_AT_alignment : 8
<42e6> DW_AT_data_member_location: 0
Now we can drill down some more to see what the special __0 member's
type looks like:
<3><44f2>: Abbrev Number: 8 (DW_TAG_structure_type)
<44f3> DW_AT_name : (indirect string, offset: 0x84c0b): String
<44f7> DW_AT_byte_size : 24
<44f8> DW_AT_alignment : 8
<4><44f9>: Abbrev Number: 9 (DW_TAG_member)
<44fa> DW_AT_name : (indirect string, offset: 0x2dac7): vec
<44fe> DW_AT_type : <0x450b>
<4502> DW_AT_alignment : 8
<4503> DW_AT_data_member_location: 0
Oops, it is a 24 byte structure type.
This seems wrong to me, I'd expect a pointer type here instead,
or a sequence of $0$nnn$mmm$... values to select such a field.
Perhaps this is another case where that rust bug you linked to causes
problems? Though you say it worked before. I can't try an older
gdb right now, but I hope to get to it eventually. I wonder if it
worked by accident or if assuming the whole 24 bytes is 0 is ok.

To my surprise I was able to reproduce this with rust 1.12.
I don't know why I didn't see that when doing the variant
part work :(

As requested by TomT, setting target milestone to 10.1 because this is a
regression (came from the variant rewrite).

I think this one fails because gdb finds the underlying
enum type rather than the type it ought to find.
However, that's because both types appear in the DWARF
with the same name.
I probably won't try to fix this one, as it is a consequence
of this strange DWARF.

FWIW with rust 1.12 I get these FAILs:

At least the last one isn't a bug, but maybe the others are.
I have patches for a number of them.

--- Comment #13 from Tom Tromey <tromey at sourceware dot org> ---
Note with 1.12, the name referenced in comment #8 is
<2><894>: Abbrev Number: 14 (DW_TAG_union_type)
<895> DW_AT_name : (indirect string, offset: 0x1415):
NonZeroOptimized
<899> DW_AT_byte_size : 24
<3><89a>: Abbrev Number: 13 (DW_TAG_member)
<89b> DW_AT_name : (indirect string, offset: 0x13eb):
RUST$ENCODED$ENUM$0$0$0$0$0$0$Empty
<89f> DW_AT_type : <0x8a5>
<8a3> DW_AT_data_member_location: 0
... which is what I would expect, this is the "drill down"
situation I mentioned there.
So, I think your compiler just has a bug here.
I've fixed the other 1.12 regressions though.
Thank you for pointing this all out.

Fix variant part regressions with older Rust compiler
Older Rust compilers used special field names, rather than DWARF
features, to express the variant parts of Rust enums. This is handled
in gdb through a quirk recognizer that rewrites the types.
Tom de Vries pointed out in PR rust/26197 that the variant part
rewrite regressed this code. This patch fixes the problems:
* Univariant enums were not handled properly. Now we simply call
alloc_rust_variant for these as well.
* There was an off-by-one error in the handling of ordinary enums.
* Ordinary enums should have the size of their member types reset to
match the size of the enclosing enum. (It's not clear to me if this
is truly necessary, but it placates a test, and this is just legacy
handling in any case.)
Tested with Rust 1.12.0, 1.14.0, 1.19.0, 1.36.0, and 1.45.0 on x86-64
Fedora 32. There were some unrelated failures with 1.14.0 and 1.19,0;
but considering that these are fairly old releases, I don't plan to
look into them unless someone complains.
Note that this patch will not fix all the issues in the PR. In that
PR, Tom is using a somewhat unusual build of Rust -- in particular it
uses an older (pre-DWARF variant part) LLVM with a newer Rust. I
believe this compiler doesn't correctly implement the old-style name
fallback; the details are in the bug.

--- Comment #16 from Tom Tromey <tromey at sourceware dot org> ---
I'm inclined to close this on the theory that this patch takes
things as far as possible.
However, I thought I'd ask first -- can you try it and see how
it fares?
I'd still expect some failures I guess, given the analysis.

I checked out commit 9852ceef -- which came before the variant part rewrite.
This version didn't work for these tests either:
(gdb) print str_some
$1 = <error reading variable>
(gdb) print str_none
$2 = <error reading variable>
(gdb) print custom_some
$3 = <error reading variable>
(gdb) print custom_none
$4 = <error reading variable>
Then I checked out the version before a1520ad8fc (see comment #6).
However, this one crashes trying to load the executable, which
maybe is why that patch exists? (I don't remember the context any more.)
Do you know of a version that passes these tests with this executable
or rust compiler version?

I've checked out a1520ad8fc^ and built it.
I'm observing the same as you, that is:
...
UNTESTED: gdb.rust/union.exp: could not run to breakpoint
UNTESTED: gdb.rust/modules.exp: could not run to breakpoint
UNTESTED: gdb.rust/simple.exp: could not run to breakpoint
UNTESTED: gdb.rust/traits.exp: could not read
/home/vries/gdb_versions/devel/build/gdb/testsuite/outputs/gdb.rust/traits/traits
with readelf
UNTESTED: gdb.rust/rust-style.exp: could not run to breakpoint
UNTESTED: gdb.rust/methods.exp: could not run to breakpoint
...
Which means that my assessment in comment 6 was wrong: this is not a regression
starting at that commit.

I've tried the you mentioned, commit 9852ceef, and get:

Ok, I see. The test accepts the bug:
set xfail_pattern " = <error reading variable>"
gdb_test_multiple "print str_some" "" {
-re "\[\r\n\]*(?:$pass_pattern)\[\r\n\]+$gdb_prompt $" {
pass $gdb_test_name
}
-re "\[\r\n\]*(?:$xfail_pattern)\[\r\n\]+$gdb_prompt $" {
xfail $gdb_test_name
}
}
I suppose we could just update the xfail pattern then.

Author: Tom Tromey <tromey@adacore.com>
Date: Mon Aug 17 10:45:49 2020 -0600
Update xfail pattern in gdb.rust/simple.exp
In PR rust/26197, Tom de Vries notes that the variant part rewrite
caused some regressions for the Rust compiler he has. This compiler
is unusual in that it combines a relatively recent rustc with a
relatively old LLVM -- so variant parts are not emitted using DWARF.
Most of the bugs in that PR were already fixed by earlier patches, but
some lingered. After some research we found that some of these never
did work -- which is consistent with the investigations we did into
the debug info -- but instead were xfail'd. This patch updates the
xfails to cope with the new output. (After this, just one failure
remains.)
Tom de Vries tested this using his rustc and suggested a fix that
appears in this version.

I suppose we could test rustc version (using --version --verbose), getting the
rustc and paired llvm version, and xfail or not based on that.

Sorry about the delay. Yeah, that would work.
Maybe just checking the LLVM version is enough.

I re-debugged this and the patch I'm about to submit has a slightly
better description of what's wrong -- namely that the rust compiler
emits two types with the same name, and gdb picks the wrong one.
This is fixed by using a later version of LLVM.

Avoid running one Rust test against older LLVM
LLVM 8.0 introduced some changes to let the Rust compiler emit DWARF
variant parts. Before this change, the compiler would emit two types
with the same name, and unfortunately gdb happens to pick the wrong
one. So, this patch disables the test when using an older version of
LLVM.
