New Revision: 1022
Modified:
branches/experimental/toiger/src/virtual-frame-ia32.cc
Log:
Experimental: the code to make a frame mergable is sometimes emitted
between an instruction that sets the processor flags and an
instruction that tests them. The flags must not be affected by the
make mergable code (mov and push is OK, xor is not).
