Hi, I'm trying to turn on a flag (-inline-generic-switch-cost) introduced in r301649 which improved the inline cost heuristic for switch. In my experiment for LLVM test suite and spec2000/2006 in AArch64, +17.82% performance and -8% code size reduce was observed in spec2000/vertex with O3 LTO. No significant code size / performance regression was found in O3/O2/Os. Before we turn this flag on by default, I want this change to be tested on other targets as well as for other app...

Are there any results for the SPEC2000 benchmarks using llvm with and without LTO? It would be interesting to know how the current LTO in llvm compares to the results being seen in current gcc trunk with their LTO... http://gcc.gnu.org/ml/gcc/2009-10/msg00155.html It would appear that the gcc LTO implementation is finally showing resu...

Dear guys, I am writing some scripts to allow me to compile the programs in SPEC2000 using llvm-gcc. I have been successfull with almost all of them, but need some help with 254.gap. I am producing a .bc file using llvm-gcc, and then a .s using llc. Then I use gcc to produce an executable. In this last phase, I am getting: /usr/bin/ld: Undefined symbols: _SyLibname _SyMemory _S...

Hello, I want to run SPEC2000 benchmark in LLVM to check correctness of a llvm module which I wrote. How to run SPEC2000 benchmark in LLVM? Unnikrishnan C -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

Dear guys, I've got SPEC2000, and now I am trying to run the tests with it. What I am doing to test it is to configure the test with --enable-spec2000=<directory>, and then I call "make TEST=nightly report.html". I would like to test only the files on SPEC, so I would like to know if any of you guys has an exam...

It appears that lnt has the capability to run the SPEC2000/2006/2017(maybe) tests from looking at the options and from poking around in the mailing list archives. Or does it? I experimented a bit and cannot get it to work right. However, it isn't really documented anywhere so maybe I didn't set it up properly. Plus there's all the menti...

Dear guys, I've put the puzzle solver running on LLVM 2.1. Well, at least partially, for it is failing three of SPEC2000 benchmarks. I will try to debug it now. The results are not as good as before. I mean, the puzzle solver is still the same, but the default allocator is producing very good code now. Even though, the puzzle solver produces faster code for half the benchmarks. It does not use instruction folding...

...o.kr/group/mailing.freebsd.hackers/browse_thread/thread/9dd9b232a5ab6a52 Apparently, people have asked how it compares to LLVM, both architecturally and performance-wise. And there are some replies from the libFirm developers in the thread mentioned above. BTW, on the project page there are some SPEC2000 performance comparisons with GCC, LLVM-GCC and Intel Compilers. It would be interesting to hear an opinion regarding those issues from the LLVM developers as well, I guess. Anyone willing to comment? In any case, this library contains a lot of interesting and related things and worse looking at...

Hi, in a thread this afternoon about compiling the Fortran SPEC2000 to LLVM bytecode, Chris mentioned that it should be possible to compile to LLVM with the gfortran front end, although no one has necessarily tried it. I was surprised (and happy) to hear this, as under the impression that it would require a "complete rewrite of the gfortran backend" [1]....
