14 years agoAdd a couple more heuristics to neuter machine cse some more.
Evan Cheng [Wed, 10 Mar 2010 02:12:03 +0000 (02:12 +0000)]
Add a couple more heuristics to neuter machine cse some more.

1. Be careful with cse "cheap" expressions. e.g. constant materialization. Only cse them when the common expression is local or in a direct predecessor. We don't want cse of cheap instruction causing other expressions to be spilled.
2. Watch out for the case where the expression doesn't itself uses a virtual register. e.g. lea of frame object. If the common expression itself is used by copies (common for passing addresses to function calls), don't perform the cse. Since these expressions do not use a register, it creates a live range but doesn't close any, we want to be very careful with increasing register pressure.

Note these are heuristics so machine cse doesn't make register allocator unhappy. Once we have proper live range splitting and re-materialization support in place, these should be evaluated again.

Now machine cse is almost always a win on llvm nightly tests on x86 and x86_64.

simplify EmitSectionOffset to always use .set if it is
available, the only thing this affects is that we produce
.set in one case we didn't before, which shouldn't harm
anything.  Make EmitSectionOffset call EmitDifference
instead of duplicating it.

Fix a crash compiling 254.gap for Thumb2.  The Thumb2 add/sub with 12-bit
immediate instructions cannot set the condition codes, so they do not have
the extra cc_out operand.  We hit an assertion during tail duplication
because the instruction being duplicated had more operands that expected.
