RFR 8202379: ARM32 is broken after JDK-8201543 (Modularize C1 GC barriers)

[Boris Ulasevich]

Hi,

   I believe the fix is not complete. I see SIGILL on ARM32 RPi (cross 
ARM32 build on Raspberry Pi) with simple command line: 
./jdk-b49938/bin/java -Xcomp -XX:+TieredCompilation -version

   I reproduced the issue starting from r49906 (8201543: Modularize C1 
GC barriers) with r49938 fix (8202379: ARM32 is broken after JDK-8201543 
(Modularize C1 GC barriers)).

# hg update -r49906
# hg diff -r49937:49938 > build_fix
# patch -p1 < build_fix
# make CONF=linux-arm-normal-server-release

   I did not dig deeper yet.

regards,
Boris
