[LLVMdev] [x86] Prefetch intrinsics and prefetchw
...1)
tail call void @llvm.prefetch(i8* %7, i32 1, i32 3, i32 1)
The generated x86_64 code for the first 4 calls, where the read/write parameter
is 0 (read) is exactly as expected:
(Generated with clang -O2 -S -march=btver2 test.c)
prefetchnta foo(%rip)
prefetcht2 foo(%rip)
prefetcht1 foo(%rip)
prefetcht0 foo(%rip)
The question is what should be expected when the r/w parameter is 1 (write).
Currently the backend generates:
prefetchnta foo(%rip)
prefetcht2 foo(%rip)
prefetcht1 foo(%rip)
prefetchw foo(%rip)
However, a different possibility would be for the r/w parameter to take
precedence over...

[GE users] Apple Leopard has dtrace -- anyone used the SGE probes/scripts yet?
Hi,
Chris (cc) and I try to get the SGE master monitor work with Apple Leopard
dtrace. Unfortunately we are stuck with the error msg below.
Anyone having an idea what could be the cause? What I can rule out as
cause is function inlining for the reasons explained below.
Background information on SGE master monitor implementation is under
