[LLVMdev] [NVPTX] Eliminate common sub-expressions in a group of similar GEPs
...ons of registers. e.g., it emits the following PTX for
the
first load and similar PTX for other loads.
mov.u32 %r1, %tid.x;
mov.u32 %r2, %tid.y;
mul.wide.u32 %rl2, %r1, 128;
mov.u64 %rl3, a;
add.s64 %rl4, %rl3, %rl2;
mul.wide.u32 %rl5, %r2, 4;
add.s64 %rl6, %rl4, %rl5;
ld.shared.f32 %f1, [%rl6];
The resultant register pressure causes up to 20% slowdown on some of our
benchmarks.
To reduce register pressure, the optimization implemented in this patch
merges
the common subexpression in a group of GEPs, saving many registers used for
pointer arithme...

Rebuild of kernel 2.6.9-67.0.20.EL failure
Hello list.
I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without
modifications.
How did I try it?
Created a (non-root) build environment (not a mock )
Installed the kernel.scr.rpm and did a
rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee
prep-out.log
The build failed at the end:
Processing files: kernel-xenU-devel-2.6.9-67.0.20.EL
