Re: [Linaro-TCWG-CI] gdb-14-branchpoint-2123-g4e417d7bb1c: FAIL: 3 regressions on aarch64

[Christophe Lyon <christophe.lyon@linaro.org>]

Hi Tom.

As you may have noticed, your patch below caused regressions in the
libstdc++ testsuite on aarch64:
FAIL: libstdc++-prettyprinters/debug.cc print redirected
FAIL: libstdc++-prettyprinters/simple.cc print redirected
FAIL: libstdc++-prettyprinters/simple11.cc print redirected

For instance, the log contains:
$24 = Traceback (most recent call last):
  File "/home/tcwg-buildslave/workspace/tcwg_gnu_5/abe/snapshots/gcc.git~master/libstdc++-v3/testsuite/../python/libstdcxx/v6/printers.py",
line 2279, in to_string
got: $24 = Traceback (most recent call last):
FAIL: libstdc++-prettyprinters/debug.cc print redirected

Do you know if this is a problem in GDB, or if the testcase needs an
adjustment like recently for another one?

Thanks,

Christophe
