So the gist of my changes is really just:
- Bool matchIRExpr ( MatchInfo* mi, IRExpr* p, IRExpr* e );
+ Bool matchIRExpr ( MatchInfo* mi, const IRExpr* p, const IRExpr* e );

Interestingly enough, VEX register allocator v2 also benefits from register

For Memcheck on perf/bz2:

Unfortunately performance measurements do not confirm this as a good idea.

At the end only %r11 was removed from the list in getRegUsage_AMD64Instr()
because it's used overall as a temporary register for destination address.

Thank you for the patch. Indeed, it unbreaks the build.
"some complaints" is an euphemism here :-)
Valgrind build was effectively broken on two thirds of supported OSes :-)

Diane, your patch does not apply to Valgrind SVN trunk.
1. It is malformed. Line 48 seems to be split somehow.
2. After correcting item 1 manually, 2 hunks in
coregrind/m_syswrap/syswrap-linux.c
fail to apply

Based on your comment #2, I prepared a patch myself.
Compared to yours, it uses completely different approach.
I will defer to the community to judge which one suits better.
