> Hi @offamitkumar this is a bit surprising because the matcher header is only included if COMPILER2 is defined https://github.com/openjdk/jdk/blob/master/src/hotspot/cpu/s390/compiledIC_s390.cpp#L32 and this should not be the case in minimal JVM , but if this somehow works on your side, then fine :-) !

I have finished tier1 on minimal build, will see if this issue gets reproduced by any of the tests.
