This test case currently fails on s390x, and probably other
platforms where the last line of a backtrace does not contain
and " at <source location>" specification.
The problem with the existing normalization lines
// normalize-stderr-test "\s*\d{1,}: .*\n" -> ""
// normalize-stderr-test "\s at .*\n" -> ""
is that \s matches all whitespace, including newlines, so the
first (but not second) of these regexes may merge multiple
lines. Thus the output differs depending on which of these
matches on the last line of a backtrace.
As the whitespace used in backtraces is just normal space
characters, change both regexes to just match at least one
space character instead:
// normalize-stderr-test " +\d{1,}: .*\n" -> ""
// normalize-stderr-test " + at .*\n" -> ""
This greatly simplifies how hard it is to set a custom bug report url; previously tools had to copy
the entire hook implementation.
- Switch clippy to the new hook
This also adds a `extra_info` callback so clippy can include its own version number, which differs
from rustc's.
- Call `install_ice_hook` in rustfmt
