siginfo: si_signo: 11 (SIGSEGV), si_code: 1 (SEGV_MAPERR), si_addr: 0x00000000e41d2718

Starting this bug as a P2 since it has happened in two Tier2
job sets in a row.
Comments
Fix Request(13u) Fix for P1 bug is required to be back ported. Applies cleanly. Pass tier1 set.
18-05-2021
Fix Request (11u). Low risk, fixes zeroing out the upper half of a pointer in an intrinsic. Review approval: https://mail.openjdk.java.net/pipermail/jdk-updates-dev/2020-October/004017.html.

Yes, that is why string_indexof_char was also fixed.
21-10-2020
This seems to have been a pre-existing issue (to JDK-8173585) that showed up due to that patch using the existing string_indexof_char method as a template for stringL_indexof_char.

Changeset: 365f19c8 Author: Sandhya Viswanathan <sviswanathan@openjdk.org> Date: 2020-10-21 16:24:30 +0000 URL: https://git.openjdk.java.net/jdk/commit/365f19c8
21-10-2020
I just finished running dsig/GenerationTests.java test multiply runs (to besure) on our systems and confirmed Sandhya's proposed fix: bsfl(ch, tmp); + addptr(result, ch); - addl(result, ch); It always fails with addl() and always passed with addptr().
20-10-2020
This issue was filed as a result of JDK-8173585, but JDK-8173585 was disabled by JDK-8254792, so nominally the segv should have gone away.
20-10-2020
Raising priority because this also shows up with other tests (JDK-8255039).
20-10-2020
If you look on si_addr: 0x00000000e41d2718 which case memory map it looks like R8 =0x00000007e41d2700 is an oop: [B with upper 32-bits zeroed. It looks like the code cut uppers 32-bits.
