a proposed script to help with test-suite programs that output _lots_ of FP numbers
Dear all,
As part of working on making test-suite less demanding of exact FP results so my FP-contraction
patch can go back into trunk and stay there, today I analyzed
"MultiSource/Benchmarks/VersaBench/beamformer". I found that the raw output from that program
is 2789780 bytes [i.e. ~2.7 _megabytes_] of floating-point text, which IMO is too much to put
into a patch -- or at least a _civilized_ patch. ;-)
As a result, I wrote the below Python program, which I think should deal with the p...

[LLVMdev] [RFC] AArch64: Should we disable GlobalMerge?
Hi all,
I've started looking at the GlobalMerge pass, enabled by default on
ARM and AArch64. I think we should reconsider that, at least for
AArch64.
As is, the pass just merges all globals together, in groups of 4KB
(AArch64, 128B on ARM).
At the time it was enabled, the general thinking was "it's almost
free, it doesn't affect performance much, we might as well use it".

[LLVMdev] IR Passes and TargetTransformInfo: Straw Man
Andy and I briefly discussed this the other day, we have not yet got
chance to list a detailed pass order
for the pre- and post- IPO scalar optimizations.
This is wish-list in our mind:
pre-IPO: based on the ordering he propose, get rid of the inlining (or
just inline tiny func), get rid of
all loop xforms...
post-IPO: get rid of inlining, or maybe we still need it, only
