This is step 2 towards fixing #77548.
In the codegen and codegen-units test suites, the `//` comment markers
were kept in order not to affect any source locations. This is because
these tests cannot be automatically `--bless`ed.
Replace old GDB and LLDB pretty-printers with new ones
which were originally written for IntelliJ Rust.
New LLDB pretty-printers support synthetic children.
New GDB/LLDB pretty-printers support all Rust types
supported by old pretty-printers, and also support:
Rc, Arc, Cell, Ref, RefCell, RefMut, HashMap, HashSet.
Bug #52452 notes some debuginfo test regressions when moving to gdb
8.1. This series will also cause versions of gdb before 8.2 to fail
when a recent LLVM is used -- DW_TAG_variant_part support was not
added until 8.2.
This patch updates one of the builders to a later version of Ubuntu,
which comes with gdb 8.2. It updates the relevant tests to require
both a new-enough LLVM and a new-enough gdb; the subsequent patch
arranges to continue testing the fallback mode.
The "gdbg" results are removed from these tests because the tests now
require a rust-enabled gdb.
If you read closely, you'll see that some of the lldb results in this
patch still look a bit strange. This will be addressed in a
subsequent patch; I believe the fix is to disable the Python
pretty-printers when lldb is rust-enabled.
If the rust-enabled lldb was built, then use it when running the
debuginfo tests. Updating the lldb submodule was necessary as this
needed a way to differentiate the rust-enabled lldb, so I added a line
to the --version output.
This adds compiletest commands to differentiate between the
rust-enabled and non-rust-enabled lldb, as is already done for gdb. A
new "rust-lldb" header directive is also added, but not used in this
patch; I plan to use it in #54004.
This updates all the tests.
- Now "make check-stage2-T-aarch64-linux-android-H-x86_64-unknown-linux-gnu" works (#21773)
- Fix & enable debuginfo tests for android (#10381)
- Fix & enable more tests for android (both for arm/aarch64)
- Enable many already-pass tests on android (both for arm/aarch64)
