It seems that -fplugin-arg-dragonegg-llvm-ir-optimize=2 provides a small offsetting reduction in compile time to compensate for the increased compile time from -fplugin-arg-dragonegg-enable-gcc-optzns at -O3 -ffast-math. It also appears that with -fplugin-arg-dragonegg-llvm-ir-optimize=2, the addition of -fplugin-arg-dragonegg-enable-gcc-optzns slows compilation by 24% with -O3 -ffast-math (which is very close to the 23% increase in compile time seen without -fplugin-arg-dragonegg-llvm-ir-optimize=2). We should rebenchmark pb05 with -O2 -ffast-math to see if -fplugin-arg-dragonegg-enable-gcc-optzns has the same impact on compile times. IMHO, if -fplugin-arg-dragonegg-enable-gcc-optzns has less effect at -O2, it would might make sense to default -fplugin-arg-dragonegg-enable-gcc-optzns on in dragonegg. That is, if the compile time regressions are mainly at -O3 that would be tolerable because run-time of the resulting binaries should be more important there.

[LLVMdev] -fplugin-arg-dragonegg-enable-gcc-optzns status
Hi Jack,> Here are the complete benchmarks rerun against gcc 4.5.4 built with...thanks for these great numbers. It is interesting to see that dropping the LLVM IR optimization level to 2 makes no difference to the run-times. As a radical experiment I just committed a patch to dragonegg (commit 132846) that disables all heavy LLVM optimizations when the GCC optimizers are enabled. A few small cleanups are run on each function, but otherwise only LLVM codegen (and codegen optimizations) are done. I did some measurements and this results in very fast compile times. But how does it impact run-time? Can you please benchmark run times with -fplugin-arg-dragonegg-enable-gcc-optzns and this patch applied (plus don't use the -fplugin-arg-dragonegg-llvm-ir-optimize option since that turns on heavy LLVM IR optimizations again). If it has no impact on run-times then that would suggest that LLVM's IR level optimizers are not doing any useful optimization: GCC already got everything. If it does have an impact then that suggests that LLVM is picking up stuff that GCC missed. I can't way to see! Thanks a lot, Duncan.> > Using built-in specs. > COLLECT_GCC=gfortran-fsf-4.5 > COLLECT_LTO_WRAPPER=/sw/lib/gcc4.5/libexec/gcc/x86_64-apple-darwin11.0.0/4.5.4/lto-wrapper > Target: x86_64-apple-darwin11.0.0 > Configured with: ../gcc-4.5.4/configure --prefix=/sw --prefix=/sw/lib/gcc4.5 --mandir=/sw/share/man --infodir=/sw/lib/gcc4.5/info --enable-languages=c,c++,fortran,objc,obj-c++,java --with-gmp=/sw --with-libiconv-prefix=/sw --with-ppl=/sw --with-cloog=/sw --with-mpc=/sw --with-system-zlib --x-includes=/usr/X11R6/include --x-libraries=/usr/X11R6/lib --program-suffix=-fsf-4.5 --enable-lto --enable-checking=release > Thread model: posix > gcc version 4.5.4 20110608 (prerelease) (GCC) > > x86_64 darwin > > A) gcc 4.5.4svn using -msse3 -ffast-math -O3 -fno-tree-vectorize > B) gcc 4.5.4svn/dragonegg using -msse3 -ffast-math -O3 -fno-tree-vectorize -fplugin-arg-dragonegg-enable-gcc-optzns > C) gcc 4.5.4svn/dragonegg using -msse3 -ffast-math -O3 -fno-tree-vectorize > D) gcc 4.5.4svn/dragonegg using -msse3 -ffast-math -O3 -fno-tree-vectorize -fplugin-arg-dragonegg-enable-gcc-optzns -fplugin-arg-dragonegg-llvm-ir-optimize=2 > E) gcc 4.5.4svn/dragonegg using -msse3 -ffast-math -O3 -fno-tree-vectorize -fplugin-arg-dragonegg-llvm-ir-optimize=2 > > Run Time (seconds) > Benchmark A) stock B) gcc 4.5.4/ C) gcc 4.5.4/ D) gcc 4.5.4/ E) gcc 4.5.4/ > gcc 4.5.4 dragonegg/optzns dragonegg dragonegg/optzns/ dragonegg/optimize=2 > optimize=2 > > ac 9.58 9.11 12.28 9.12 12.73 > aermod 20.99 16.18 17.86 16.30 17.89 > air 6.06 6.58 7.69 6.51 7.64 > capacita 35.76 39.86 46.10 39.58 45.89 > channel 2.03 2.04 1.96 2.04 1.96 > doduc 28.16 28.50 30.34 28.53 30.42 > fatigue 8.12 7.09 10.34 7.06 10.25 > gas_dyn 10.16 9.92 11.67 9.96 11.81 > induct 20.14 20.76 48.75 20.78 48.75 > linpk 15.43 15.41 15.64 15.41 15.64 > mdbx 11.41 11.72 12.11 11.72 12.07 > nf 27.90 28.52 29.26 28.42 29.13 > protein 38.65 38.72 41.31 38.75 39.49 > rnflow 27.22 28.18 31.81 28.15 31.98 > test_fpu 11.49 11.23 11.57 11.17 11.52 > tfft 1.91 1.95 2.15 1.95 2.16 > > Mean 12.72 12.60 14.73 12.59 14.72 > > Compile Time (seconds) > Benchmark A) stock B) gcc 4.5.4/ C) gcc 4.5.4/ D) gcc 4.5.4/ E) gcc 4.5.4/ > gcc 4.5.4 dragonegg/optzns dragonegg dragonegg/optzns/ dragonegg/optimize=2 > optimize=2 > > ac 0.86 0.44 0.31 0.41 0.28 > aermod 31.13 25.81 20.94 25.44 20.87 > air 1.74 1.48 0.81 1.46 0.78 > capacita 0.86 0.74 0.44 0.71 0.42 > channel 0.35 0.32 0.23 0.30 0.23 > doduc 3.08 2.63 1.63 2.60 1.58 > fatigue 1.04 1.05 0.89 0.90 0.70 > gas_dyn 0.94 0.94 0.75 0.84 0.62 > induct 3.30 2.52 1.84 2.36 1.66 > linpk 0.33 0.28 0.20 0.28 0.20 > mdbx 1.09 1.02 0.60 0.99 0.59 > nf 0.41 0.40 0.28 0.40 0.28 > protein 1.56 1.28 0.98 1.21 0.82 > rnflow 1.75 1.70 1.24 1.61 1.13 > test_fpu 1.38 1.41 1.05 1.31 0.95 > tfft 0.31 0.28 0.19 0.28 0.19 > > Executable Size (bytes) > Benchmark A) stock B) gcc 4.5.4/ C) gcc 4.5.4/ D) gcc 4.5.4/ E) gcc 4.5.4/ > gcc 4.5.4 dragonegg/optzns dragonegg dragonegg/optzns/ dragonegg/optimize=2 > optimize=2 > > ac 26344 30896 26704 30896 26824 > aermod 1145924 1043816 1052056 1027680 1031880 > air 57404 57700 53532 53556 53532 > capacita 40864 41008 37064 41008 37064 > channel 22448 22664 22664 22664 22664 > doduc 127340 124108 120124 124372 120484 > fatigue 61152 65352 65664 61256 61568 > gas_dyn 647864 58768 59024 54672 54960 > induct 162360 180440 175312 168304 163176 > linpk 18112 18848 18864 18848 18896 > mdbx 53464 57652 49516 57652 49516 > nf 22560 23784 24080 23784 24080 > protein 74320 74440 74816 70344 66624 > rnflow 66040 71488 71648 67416 67616 > test_fpu 52624 58224 58320 54128 54256 > tfft 18416 18456 18600 18456 18600 > >
