Description
ctw/maven2/avalon-composition/avalon-composition-impl/1_2_5/avalon-composition-impl-1_2_5_jar/org_apache_avalon_composition_util_StringHelper failed crashing the VM during HS23b05 JDK8b13 PIT. Not reproducible with -Xint. It's a compiler issue. However, reproducible both with -client and -server. Initially assigning C1 subcategory for this CR.

To reproduce,

1. ssh -luadmin to sc14160083
2. /export/local/common/jdk/baseline/solaris-amd64/bin/java -Xcomp -server -d64 -Xverify:all -XX:+CompileTheWorld -XX:CompileTheWorldStartAt=42 -XX:CompileTheWorldStopAt=43 -XX:LogFile=hotspot_42.log -XX:MaxPermSize=384M -Xmx512M -Xbootclasspath/p:/net/sqenfs-1.us.oracle.com/export1/comp/vm/testbase/ctw/full/maven2/avalon-composition/avalon-composition-impl/1.2.5/avalon-composition-impl-1.2.5.jar

Distance is too large for one short branch in string_indexofC8(). Note, it does not fail always because different REX prefixes are generated for different input registers.

I added verification code in debug VM by reducing allowed distance (by 32 bytes) for short branches. It can be used in a large hand written assembler code.

Distance is too large for next conditional branch in MacroAssembler::string_indexofC8()

    jccb(Assembler::noOverflow, RELOAD_SUBSTR); // OF == 0
