distinction between primary and secondary build targets, and (2) make
it independent of the default behaviour of gcc (iow, what gcc does
when you specify neither -m32 nor -m64).
As a result, an out-of-the-box build on ppc64-linux now builds a
system which is basically for 64-bit PowerPC, but also has the ability
to run 32-bit ppc-linux binaries (exactly the same arrangement as you
get when building on amd64-linux).
There are various twists and turns. multiple-architectures.txt is
updated all the gory details.
This will break amd64 builds until such time as
<tool>/tests/{amd64,x86}/Makefile.am are fixed up (shortly).

program more uniformly measures the speed of FP +/-/* load/store
across different architectures.

x86 isms in tinycc.c, (2) giving it a fixed, preprocessed input file
to chew on, and (3) just compiling to a .o with no attempt to link.

(use "make perf" to run) that executes test programs and times their
slowdowns under various tools. It works a lot like the vg_regtest script.
It's a bit rough around the edges -- eg. you can't currently directly
compare two different versions of Valgrind, which would be useful -- but it
is a good start.
There are currently two test programs in perf/. More will be added as time
goes on. This stuff will be built on so that performance changes can be
tracked over time.
