[LLVMdev] [NVPTX] Eliminate common sub-expressions in a group of similar GEPs
...at literally computes the pointer address
of
each GEP, wasting tons 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...
