[rvm-research] Bytecode merge is disabled for aload in Baseline compiler

Hi, I'm a newbee who tries to understand how a basic JIT compiler works.
During digging the baseline compiler codes for ia32, I cannot understand
the following quetion:

In org.jikesrvm.compilers.baseline.BaselineCompiler, emit_aload() method
comments out bcodes.peekNextOpcode(), which technically disables the
possibility to merge with getfield. Meanwhile emit_iload(), emit_lcmp()
allows merges. Is there any consideration for this regression?



Regards.
Lingyu Zhu.
