The following patch is result of libsanitizer/merge.sh
from c425db2eb558c263 (yesterday evening).
Bootstrapped/regtested on x86_64-linux and i686-linux (together with
the follow-up 3 patches I'm about to post).
BTW, seems upstream has added riscv64 support for I think lsan/tsan,
so if anyone is willing to try it there, it would be a matter of
copying e.g. the s390*-*-linux* libsanitizer/configure.tgt entry
to riscv64-*-linux* with the obvious s/s390x/riscv64/ change in it.
Merged from revision b638b63b99d66786cb37336292604a2ae3490cfd.
The patch successfully bootstraps on x86_64-linux-gnu and
ppc64le-linux-gnu. I also tested ppc64-linux-gnu that exposed:
https://reviews.llvm.org/D80864 (which is fixed on master).
Abidiff looks happy and I made UBSAN and ASAN bootstrap on
x86_64-linux-gnu.
I'm planning to do merge from master twice a year, once now and
next time short before stage1 closes.
I am going to install the patches as merge from master is obvious
and I haven't made anything special.
libsanitizer/ChangeLog:
* MERGE: Merge from master.
