Hi,
I've run a build for spec cpu2006 with -O3 -ftree-parallelize-loops=16
and interestingly there were some fails that I will investigate later.
So I'm just reporting these, and asking for somebody who could fix
the link options for autopar. I'm attaching a patch, not sure it will build.
Before going in the depths of the build machinery, I'm asking if
somebody could help with this.
Benchmarks ICEing:
400.perlbench
401.bzip2
403.gcc
445.gobmk
456.hmmer
458.sjeng
462.libquantum
464.h264ref
471.omnetpp
473.astar
483.xalancbmk
416.gamess
434.zeusmp
435.gromacs
436.cactusADM
437.leslie3d
444.namd
447.dealII
453.povray
454.calculix
459.GemsFDTD
465.tonto
470.lbm
481.wrf
482.sphinx3
Not ICEing, but failing on the link step, can't find the libgomp functions:
429.mcf
433.milc
450.soplex
For these a patch like this would be needed to automatically link the
gomp and pthread libs.
