Okay, can you resummarize? Do you mean that?
gcc -O0:
S1421 0.00 16000
gcc -O0 under valgrind:
S1421 0.00 17208.404325315
clang:
S1421 0.00 17208.404325315
This is all on Darwin, right?
I would certainly tend to suspect an 80-bit-intermediate issue, but, both gcc and clang give 16000 on PowerP...

Hi Hal, I was looking into why this fails with dragonegg, and noticed the
following: if I compile with GCC (-O0) then I get as output:
Running each loop 3125 times...
Loop Time(Sec) Checksum
S421 0.00 32010.620068485
S1421 0.00 16000
S422 0.00 3.7377231414078
S423 0.00 32000.736895702
S424 0.00 32822.36069424
This is the same as the reference output. If I run exactly the same program
under valgrind then I get:
Running each loop 3125 times...
Loop Time(Sec) Checksum
S421 0.00 32010.620068485

PS: Here's how I can reproduce with clang on linux:
clang -S -o tsc.ll -O0 -flto -std=gnu99 tsc.c ; clang -S -o dummy.ll -O0 -flto
-std=gnu99 dummy.c ; opt -std-compile-opts tsc.ll -S -o tsc.1.ll ; opt
-std-compile-opts dummy.ll -S -o dummy.1.ll ; llvm-link tsc.1.ll dummy.1.ll -S
-o total.ll ; opt -std-link-opts total.ll -S -o total.1.ll ; llc total.1.ll ;
gcc -o z total.1.s
